Normally I'd never write a review for LabCorp, but years of dealing with their condescending…read moreemployees sent my temper boiling over this afternoon. In terms of speed of service, these guys have typically always been fine, in my experience. I've never made an appointment, have always been a walk-in, and am seen almost immediately. Very little wait time. No issue with cleanliness, either. The issue is, 100%, the disgruntled jerks they seem to exclusively hire. Whoever is behind the counter at any given time (usually an older white woman with glasses) is never, ever pleasant. Not even decent. Just these grumbling, unhappy people who foist their bad day -- which seems to be every day -- onto patients. And I get it -- just sitting in there this afternoon you had one guy who comes in, obliviously crashes right into the table next to the door, and doesn't move it back, and a patient who had to be told twice which room to go into. People don't listen and they have rotten attitudes. But unless they've demonstrated rudeness or stupidity, there's no reason to treat people poorly. So when I walked up this afternoon and saw a sign that read the following, I read it as, "this place is appointment-only except during a short period in the morning": "Effective 9/25 until further notice: Due to unforeseen event [typo on their part], San Leandro location will be appointment only with accepting walk-ins when time permits from 7:00-8:30 am." I'm an English major and a content marketer, meaning, I write for a living. Anyone with a basic grasp of English would likely read this as I stated above: appointment-only location except during this short window in the morning, if time permits. Well apparently their phlebotomist, the middle-aged Asian woman who always wears her hair in a ponytail, thinks their poor, typo-riddled writing is so sublime that confusion on my part was just me being either too lazy or stupid to read the whole sign. Because when I asked her if they're appointment-only, she snidely remarked that if I'd read the whole sign, I'd see that they're only appointment-only in the morning. Apparently, what they meant to write was that they're appointment-only from 7:00-8:30 am, with the ability to squeeze in walk-ins during that window only as time permits. Not hard to write unless you're more focused on making everyone around you as miserable as you. I was extremely close to reading the phlebotomist the riot act, but I don't need to get myself banned from a LabCorp so close to my house, which I need regularly. So I just made sure to give her back her attitude in spades the entire visit and wasn't nearly as nice to her as I usually am. She seemed to be picking up what I was putting down because she tried to be nicer in the end. Way too late to play that game with me.

I was surprised that it was a full house this morning around 8am but I learned it's best to come on a Tues/Wed/Thurs based on advice. Jessie provided thorough care. She's tactful and extremely entertaining. Loved her vibes! She was gentle even when my vein needed a reboot, the pain was tolerable without being too scary. I wish I could say it's super easily available to make an appointment but it's not. However, walk in's usually come and go pretty quickly. Today was just an extraordinary day. Record-breaking for me in fact. But Jessie and the front desk staff member were really professional and friendly throughout the entire process. I'm grateful that my questions were answered willfully. Scarred for life from a Crunch Fitness customer service experience. So it gives me a lot of appreciation for excellent customer service. Thank you and take good care!

I went with an appointment at 9:45am on a Thursday I could have been in and out but I waited to have my blood drawn laying down so I waited 10 mins for the bed since there's only one.

Very unprofessional and disrespectful experience…read more I had a 12:40 PM appointment on September 2, 2026, and had already been waiting for a while. I briefly stepped away to make a phone call and did not hear my name being called. When I returned, I asked whether they had called my name. A staff member then asked another colleague whether she had called my name. During that exchange, the staff member stated, "these people, man." She said it loudly and within my hearing. I had already been waiting beyond my scheduled appointment time, and briefly stepping away and missing my name being called did not warrant a derogatory comment from a staff member. If there was an issue, it could have simply been communicated to me professionally. Patients deserve to be treated with dignity and respect. Referring to a patient as "these people" while speaking to coworkers is inappropriate and unprofessional, especially in a healthcare setting.

I have arrived at 6:45, the wait time that I was given was 19 minutes with the option to wait in the car and receive a text when it's my turn. I have been waiting an hour and a half. They have been letting people walk-in, appointment-less, and it is official that they ignored my check in! This is very annoying and irresponsible on their behalf. I had to wait in lone for another 10 minutes before another employee came out to let people in. Immediately, I walked up to her and politely demanded she let me in.

You have earned this review another star Overall cleanliness, decent. Plenty of parking. Customer service- Juhmer has exceptional customer service skills.

I told them I tend to faint when giving blood and need to lie down, but they said they 'don't do that' and had me sit in a chair instead. To make small talk I asked the tech why they decided to become a phlebotomist and she said it was because she had a shopping addiction. Nice. She tries twice to get my vein but cannot find it and I'm starting to feel woozy. Then, she goes to get help and leaves me sitting with the needle partially in my arm. I pass out and they get upset at me and then have me leave. To be honest, I cried after that appointment. It was humiliating and I'm never going back to this location.
