    Excessive bleeding from a blown vein. Swollen in just mins after the visit.
    Maripily M.

    Been using Quest for years. Quest tends to have the most unpleasant rude staff at times. They don't uphold to their policy. I've heard of ppl being turned away or made to wait bc they weren't in the lobby. Sometimes the lobby is full, others, ppl have immune compromise so they can't really wait in a room full of ppl. They call your name for a split second then quickly shut the door and skip your name. When asked even after being called for a second and being by the door at times why they would put you back in the lobby to wait until they decide to call you is absurd. Their policy is 15 mins grace period even if you are late and upon checking in they need to call you. Not make you wait and wait. Blowing your vein and causing a blood leak is not cool either! Perhaps they need to get more training and empathy classes. I mean everyone else in a professional field has to take those classes. Maybe it's time!

    Check-in was easy at the kiosk. I was called in a little early and finished in just a few minutes. Staff was very polite and professional.

    Automated Phone system to make an appointment took forever and the wait time once you arrive is a joke.

    Linda, who drew my blood, was very friendly and talked to me during the process so I wasn't nervous at all.

    My wife came in today for scheduled bloodwork for my son. He had an appointment for 3:30 PM, and…read moreupon arrival, they checked in and were put in queue as it showed on the screen in the lobby. Given a Friday afternoon, it was crowded, but saw my son's name on the list confirmed they would be seen in order. As they waited, a lady came in and got the attention from the staff, and asked for a walk in, claiming she had an appointment. She didn't but they somehow gave her a spot. As my wife waited, seemingly longer, they noticed that my son's name was no longer on the monitor queue. Other customers were being called in, including some that arrived after them. My wife finally got a staff member's attention and told her the situation. The "rude" female insisted that they had no control over what the screen showed. (Odd that you can literally put people on the walk in queue but have no say with actual scheduled customers, BS). Long story short, they ended having to wait until all customers were seen, including walk appointments. After, pleading with the staff member that we were scheduled, they did nothing to help and made us wait until closing. Again, scheduled appointments are confirmed via text and email if you have been here. But no attempt to fix the situation. The worst experience ever at Quest (given we've been here several times and haven't had an issue). The horrible, staff member who would not help, and to top it off, she kept telling customers how busy they were because they were short staffed. That is no excuse when assisting customers. Second, saying that they had no control over the queue when they were clearly able to take walk ins, but mysteriously removed my son from the list. We've been to this location before, but it seems that horrible employees lower the standard of customer service and the overall business. Even worse is that so many people rely on Quest because many private doctor's offices do not handle internal bloodwork; so Quest has this massive contract with nationwide offices to do bloodwork for them. The customers who rely on Quest are our family members, whether sick, elderly, some dealing with major medical issues, yet they might come here and have to deal with the BS that my family dealt with today. Just horrible. Hoping to figure out if there is actual management or staff supervision to bring this issue to.

I checked in using the kiosk machine and it recognized my information as having an appointment. when my name was finally called. I went to the back room and they started asking me questions and stated they did not have an order for me and I would need to Leave. I tried calling right in front of them The Doctor Who referred me and they insisted I step outside. Very frustrating. I was able to call the Dr who set this up and they mentioned all my information was in the Quantom portal. As soon as I had gotten off the phone they called me back in.

The waiting room was full and there was a line out the door. I waited about 30 minutes till an open seat was available to wait inside as it was starting to warm up. We were told they were behind an hour so there was definitely going to be a wait. Everyone was getting impatient, myself included. Many people rescheduled and left but I waited it out. It took about an hour and a half wait from my arrival to be seen. Once I got called back, everything was quick and easy. The technician who drew my blood was friendly, gentle and professional.

The place is small especially the waiting room is packed with people cramped inside not to mention, standing room only. It's outdated, unclean & unsanitary. Front desk staff looked miserable and unfriendly. Waited patiently outside the facility in the hope of getting called soon for my 7:15am appt. Got called in within 20 mins. While waiting outside with 7 other people also waiting, you can't even hear your name called out since there is no intercom or loudspeaker available. Phlebotomist was nice, the only thing positive and with effort around here. Please consider MOVING to a bigger, newer location to accommodate patients' needs efficiently. A Labcorp in Chino Hills sounds nice.
