Part of this is my fault. If you are using an outside lab to do your blood and urine work, don't assume that it will be in-network That being said, I know that I am a hard person to draw blood from as my veins roll inside my system. It is a frustrating experience to undergo a fasting blood draw only to have to technician give up without completing the draw leaving me feeling that I am wasting my time. The ones that were successful in drawing my blood were quite professional and positive. I would suggest to the call center management to set up urine experiences with the technician prepared to receive the sample. Also, there needs to be an understanding that paperwork including bills may need to be sent somewhere other than where the blood draw took place. On the rating score I will give a 4. read more

Terrible lab. Phone is broken. No-one calls back. They don't show up when expected. Really not sure how they are still in business. Stay away. read more

The worst lab I have ever had the misfortune to deal with. Completely incompetent, unreliable, with zero accountability. Continuously miss scheduled appointments 3 days in a row! Then have the audacity to say "YOU cancelled or YOU rescheduled!"DO NOT USE THIS LAB read more

They are not respecting the appointment that they are giving. My appointment was at 10 am but they didn't show up and nobody has the courtesy to call and say they' will be late. I called them and stayed on the line for at least 5-10 minutes and they told me someone will show up before 5 pm. The appointment at 10 am they will show up before 5 pm I have nothing else to do just wait for them you tell me if this is right. read more

Owner is nice but the supervisor is very rude. Not sure what her problem is but from the moment I walked in there's a disgusting vibe in there. Very odd. Grace is her name. read more

This laboratory exhibits poor communication between schedulers and field technicians. I made several calls to the main number to coordinate my needs and sadly no one was able to verify appointments I made just 24 hours prior. Perhaps their 30+ mile radius of service area is unrealistic. read more

WORST SERVICE EVer Believe all the other reviews on how unreliable and disrespectful they are! read more

had a very bad experience with MS Diagnostic Laboratory, LLC at 128 Olive Avenue, Monrovia, CA 91016. They came to take my blood work, but they missed several important tests. Because of their mistake, I had to spend a week working with Medicare to get everything redone, which was a huge inconvenience and caused me a lot of stress. When I called the lab to try to resolve the issue, the staff were extremely unprofessional. They actually hung up on me and then blocked my calls instead of helping me fix the problem. That is not the way any medical business should treat patients. Because of this experience, I cannot recommend this place to anyone. Patients deserve professionalism, accuracy, and respect--unfortunately, I did not receive that here. read more

Sarai the field technician was incompetent. She was so flustered and in such a hurry that she spilled a vial of my blood on the floor and had to draw blood again. Worst experience ever. read more

Disorganized, unreliable and horrendous communication. Terrible customer service for families often dealing with catastrophic illness. They harass people with endless phone calls, but are unreliable on their own end and fail to do their job and pick up samples read more

MS diagnostic is one of the few providers of in home medical testing. I see a lot of complaints about rude home service. I think it's more a matter of a tight schedule, they have a lot of patients to visit. I've used the service many years, and since I live right off the 10 freeway at the 710 freeway I am one of their first stops in the early morning as they are on their way to downtown Los Angeles where the bulk of their clients are. They may not be the most personable service providers, but it sure beats going in person to a crowded lab where you're surrounded by sick patients, and perhaps dozens of employees, some coughing and sneezing, that you are exposed to. One-on-one in your own home is always the best. It is true they are very lacking in providing sample containers for you to fill. They have called me from my street asking if I have samples ready for pick up, I tell them I don't have the plastic containers to fill. I ask them to drop them off and I'll have them ready by the next day. I'm sure they have dozens of empties with them. They always refuse to drop them off when they are in my area, instead having their Monrovia office mail them to me. Often just one container, when most patients need two. It can take a week to get the containers by mail, delaying vital test results. The instructions they mail you with the sample containers are faint, illegible xerox copies. You can't even read their phone number. read more

They won't stop calling me every day I get phone calls and I don't have any thing to do with them I ask them to take my number off there computer and call them but they only will let me leave a voice message when I tried to that the machine said the mail box is full there's issues I think they are making this up why they call a every day it is awful read more

the supervisor grace they do a lot of illegal things. I was only there for 7 months and they let Alot of people go left and right over the time I was there it was over 7 people. They treat their employees like garbage and extremely over work them and keep adding to their day making people work over 10-13 hrs. Super underpaid and do not even pay the legal limit for mileage. Grace is completely insane and so is Montano. Grace talks down to their employees and likes to name call and if you don't do what she says at her time rate she just yells at you for everything and calls you names. They just care about their money and not the sanity of employees DO NOT WORK HERE! M Helpful & Share read more

The worst customer service and employees, the supervisor called my husband Hard stick because they could not find his vein. Rudest people you can come in contact with. I give them a zero rating. And now they don't answer my calls. read more

I can't speak to the accuracy of their lab results, but based on their staff I wouldn't trust them to test my dog poo... unprofessional, uneducated young women that obviously hate their jobs and it comes through in their horrible attitudes, lack of customer service and inability to articulate a thought. GO ELSEWHERE! All these one star reviews aren't by chance... read more

More than 90 minutes late to draw blood. I called at 25 minute late mark and left VM. Received text he was at another stop leaving. Would be here in 25. A hour later was still not there and texted. Said he was 15 minutes away. Non apologetic upon arrival. Flippant. Unfocused. Appears he made a more geographically friendly stop before instead if keeping commitment to come. This is through hospice. read more

This laboratory came to draw my mom's blood did not leave a cup for your urine sample then they keep calling me to see if the urine is ready when I don't even have a cup and then I get a call from the office every two hours asking if the urine is ready when I specifically said the urine wasn't for five straight days bcuz they forgot to leave a urine cup and the day of the urine and pick up Maribel calls me at 6:30am (too early) to pick up when we agreed after 10 AM lack of communication and horrible service attention Grace read more

Please don't wast your time and find other place for blood texting and other diagnostic test. They have very unprofessional stuff, no proper management to received Dr's order and properly scheduled per MD's order. They are scheduling from 9-5 and end of the day calling and telling that " don't have a availability/phlebotomist for scheduled test and rescheduling for next day again from 9-5. All 2 days patient must be seat at home 9-5 pm and waiting for them. You will be lucky if they come. They don't offer home service patient with venous devices like PICC line.No same day delivery of tubes or other necessary items in order to process the lab work. I know it's not STAT LABORATORIES but at list with simple lab test scheduling must be professional. Very unsatisfied. Even 1 star not deserving. read more

Yelp needs to make an update where 0 stars is an option. This lab is completely horrible. Their customer service is horrendous. They don't even allow you to speak before they put you on hold. You're on hold for over 15mns almost every time. The time frame that they provide patients is ridiculous. How is 8-5:30 pm a good timeframe? That means the patient would have to be home all day and they might end up being the last patient on the route, so they just gave up an entire day for this. They lie to protect themselves, they're unreliable, and their manager GRACE is just as bad, if not worse. She has an attitude when speaking to her. I'm sorry but you're in the medical/ customer service field, and you will get angry people calling, you need to learn to keep your composure. What if someone spoke to her mother the way she speaks to people...... The phlebotomist don't even carry enough supplies. You can't even email a top supervisor, not Grace, directly. How will I even feel comfortable emailing the general email to reach upper management? What if they don't even forward it to him. Honestly, patients should stop using them as well as home health agencies. read more

Can I give zero stars? They have been taking my blood every other day for a month and it turns out they have not sent the data to my doctors, nor have my doctors ever heard of them. Obviously scammers. read more

I have a bed bound paraplegia daughter that is confined to bed. I have had MS laboratory bi-weekly for the past 13 years for my daughter. That is a long time and I can honestly say that I have had no problem with the service that we have received. The staff is kind and always on time. When I have called the lab my call is promptly answered. I am quite surprised by the negative reviews on here as I honestly love using their service. read more

Great & fast service! Highly recommend them if you want to do your appointment right in the comfort in your house. They do COVID now as well

This mobile lab is great. I did COVID test outside my house. Very fast & great service!

The worst, lost sample; then within 5 weeks- Did wrong test on another sample, so now never know if my husband had this serious bacteria as he has been on heavy dose of 2 antibiotics since. I agree phlebotomists are competent, but they need a different way to track what they are doing...playing with people's lives Try and find alternate read more

Is there a a 0 stars?? Sadly not, but I have never seen more incompetent, unprofessional, disorganized chop shop. The phlebotomists I met so far are nice but sadly that has nothing to do with how they run this company. The management or the founder should really check in once in a while on their employees and the team overall and do a major purge! They are clueless what's happening within... constantly forgetful about running the correct tests (as ordered by a physician), not organized about the time, basically not organized at all. There is always an excuse. Hey, guess what, I live in LA too. We all have traffic, we all have jobs so plan accordingly and take ginseng in you have memory issues. And yes the only sad reason they are even exist since home care agencies use them, which is a mistake! read more

I need to have a sick relative get two blood draws per month for the next 12 months. First month they showed up on the wrong day both times. Explained to everyone who would listen the importance of blood draws being done on the day the doctor ordered as its dependent on when chemo regime starts. Next month, they arrive on wrong day both times and believe there should be 3 draws, because they had no record of the first draw they took. 3 days in a row I called asking to speak to a supervisor and leaving a message. 2 weeks later and still no return phone call. WORST AND MOST INCOMPETENT organization I've ever had to deal with. They would get a minus 16 if YELP would allow such a score (and that is being generous!) read more

It is offensive to me that a company allegedly intended to serve the home bound disabled community is so disrespectful to its patrons. They can't even tell me whether they will be here to draw my blood in the morning or afternoon. The time estimate I was given was 8 am to 530 pm. They called me Wednesday morning to tell me they would show up some time before 6 pm. I explained I had another appointment that afternoon so could they be more specific. The Lab scheduler got all pissy with me whining "we just got the order" and cant be more specific. So I ask for another day. I suggest Friday. Again, I am told it will be between 830 and 530. Would anyone but the disabled be expected to tolerate that? Shameful. I am going to ask my doctor to stop using them. Yes I am disabled and homebound. But I also run my own business and have a life that involves more than waiting 9 hours for a blood draw. read more

It's always SOOOOOOO hard to get ahold of someone, I have to literally dial the number 20 times for it to ring and then they put me on hold for 15+ minutes and it's a pain because I call frequently read more

Worst diagnostic company around. Read all the reviews to confirm. If you can get away with using ANY other lab, do it! They are morons there, they don't update any info, they don't speak English, they don't listen, they repeatedly call, even tho you try to update your call back number, they are a mess, nobody knows what's going on. Goodluck trying to reach a human there, seems like they are trained not to answer their phones. Worst company I've ever dealt with! Our seniors/veterans deserve better! read more

Horrible is an understatement! The ONLY reason why this company is still in business is because they work with home healths and other similar companies that send their patients to them. Stay away if you can. They will promise to visit within a specific time range, but do not follow through. What if the person has a doctor's appointment? What if they have another important appointment that day? What if they are extremely sick and in dire need of the ordered blood test? What makes you think they have all day to sit at home and wait for you. They don't even call you to say that they're running late. Extremely unprofessional and rude. You're dealing with sick patients who are vulnerable!!!! Shame on you for treating them this way. read more

This place is absolutely horrible. They do not show up when scheduled (either 7 hours late, or at times next day). While other labs provide results same day, or next day, this place takes 5 days at best. Phones are always busy, and impossible to get hold of anyone. I have no idea why home care places use this place, but have to assume that $ are involved. read more

Today my mother was in need of a mobile lab draw MS Labratory was called once they arrived the technician Samantha came in Samantha made eye contact with my mother communicated well with my mother my mother was very comfortable with Samantha's presence Samantha has a great kind gift we were so impressed with Samantha I intern called MS Labratory and spoke with the manager Grace Grace was equally as exceptional as Samantha was. During this global pandemic that is unprecedented for the history of the world...Grace under pressure is all I can say for MS Labratory they are doing a five star outstanding job! MS LABS was one of the only mobile labs to continue service at the peak of the pandemic crisis at the moment of the outbreak. Grace and all of her technicians are truly our new front line heroes. They are sacrificing their lives and the lives of their families and loved ones to service us and our families and our love ones. We can not take this great service and gift for granted especially during these unprecedented times. I am forever grateful to Grace and Samantha and all the care we get and receive from all the technicians at MS Labratory a huge congratulations! An incredible thank you! A huge bravo! Keep up the good work thank you all very much thank you Grace! Amazing grace and staff! Thank you!!!! Ms. T.A. Carter, Los Angeles read more

Excellent service, from answering the phone right away and emails. Their technician was professional caring, and had a very light hand, making the blood draw painless. I highly recommend this awsome, affordable service! read more

The worst company I've ever dealt with in my life. Nobody in charge! What company has their scheduler call clients before 7:00am in the morning to ask if they can schedule an appointment for that same day? M&S labs. You're Fired! read more

The most incompetent people work here, I give them 2 hours room to come and visit me at home, they still can not keep the time, this place is a big NO NO, a joke, I am amazed how the hell they still stay in buissnes. Make yourself a favor and find another lab. Somebody should shot down this place. read more

It is always a pleasure working with professionals. They always send technicians on time for patients to get services, great communication from the entire group. read more

MS Diagnostic Laboratory is an "Ambulance Chasing" type of company! They go after any patient that is in need of home medical care, EVEN WHEN they are not authorized by your Doctor or Medical advisor! They obtain personal medical records without the patient's permission, and then send you texts, phone call and even personal visits to take blood for diagnostic purposes....WITHOUT THE KNOWLEDGE OR PERMISSION OF YOU MEDICAL DOCTOR OR ADVISOR! and then they bill medicare for that service. THIS IS A COMPANY THAT MUST BE STOPPED!! I personally have told them by both Phone and Text that I am already under the care of another medical Diagnostic company that had been arranged through my Doctors office, BUT THEY STILL SHOWED UP AT MY FRONT DOOR FOR UNNEEDED AND DUPLICATIVE BLOODWORK!! Be aware, that if you allow them to take and test blood samples when you ALREADY have another medical lab doing the same thing, Medicare could choose NOT to pay them, - and then they bill the patient directly, making the patient the scapegoat for their reimbursement! BEWARE OF THIS COMPANY........EVERYTHING THEY DO IS EITHER ILLEGAL or at the very least ........HIGHLY QUESTIONABLE!! read more

Good is an understatement. Excellent is the word I would use for the service I received. Thank you for all the assistances you've provided!

The lab employees are very rude and not very professional. They give lab reports late they miss their appointments and the constantly loose orders. Bell is extremely rude!!!! She hung up the phone on me because she didn't know the answer to my question. They do not even deserve a one star. read more

If you're looking for a place that will come to you, MS Diagnostic Laboratory might be the answer...my dad had a stroke a few years ago, he is on a blood thinner and requires weekly blood draws..it is so much more convenient to have someone come out to our house every week instead of having to take him to the lab ..everyone is friendly and professional..I highly recommend this place read more
