Labcorp

Infinite times better than Quest.

Quest was a doozy, tried calling ahead with no luck to speaking with someone (i wanted to double check it was okay to show up without a physical copy of lab order), showed up and they're backed up on appointments so walk-ins aren't really advised. Overall just a bad vibe, maybe it didn't help seeing all the negative reviews... Sat for 20 minutes and someone comes out and states that they're understaffed and backed up so there's no guarantees for walk-ins.
I got my doctor to change my lab order to Labcorp the same day and got everything done within an hour.
Called in, spoke to an actual human that was incredibly helpful. Came in and was greeted by two wonderful receptionists, had to thank them profusely for actually being there to assist with check in (compared to Quest's kiosk with no one at the desk to help with questions).

I absolutely had to emphasize the difference between LabCorp and Quest. Super happy i was able to maneuver around the Quest roadblock.

Great service Great and friendly workers/technicians this location is the best. Had to drive all the way after denied service in the Castro Valley location but they are the best.

The staff was very nice. My husband and I both had appointments we checked in at our car and we were out before our first appointment time. The lady that took my blood was excellent it didn't even hurt and I'm not usually easy to get a vein she did it the first try with no pain. Normally it is a painful for me to give blood. Excellent job.
