I have had good experiences with pain free blood draws at the Castro Valley location. However, this…read moreone is awful. I arrived for my appointment and checked in but had to wait over an hour to be seen. 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.

I've been thinking about getting rid of my popcorn ceilings, and apparently there's a good chance…read morethat popcorn ceilings contain asbestos. So in order to know for sure, I just had to take a sample (a few scrapings in a ziploc bag) and drop it in the mail to Forensic Analytical Labs with the custody form. (and thankfully I didn't have any trouble with G-men busting down my door for sending a white, powdery substance in the mail!!) Anyway, the day after I sent it in the mail, they called me to get some credit card info, and the day after that, I had a pdf report emailed to me telling me that the sample contained 5% asbestos, of the chrysotile variety. 5-stars because the cost was only $50 (equal or less than most competition), the report turn-around time was faster than all the other quotes I was given (and they delivered on their promise), and the few people I talked to on the phone were all very helpful!

I've had to use this laboratory as part of an on-going job and I have found them to be arrogant and…read moreuncooperative. I had one batch of a samples rejected because they claimed the same sample number was used twice, when one of the two entries in question was clearly labed "void." Rather than work with the inevitable minor errors made in the field and calling to correct them over the phone, they reject entire batches and make pointed remarks on the chain of custody. I am on the verge of packing my sample up and sending them off to a lab on the east coast that knows the meaning of customer service. ______________________________________________________ 8/24/11: I am happy to say that I did receive a call from a member of the management of this laboratory today. They discussed my concerns in a professional matter and listened to some of the details as to why I felt their customer service was less than desirable. For now, I'm upping my rating one star. I do appreciate the follow up call. I may up it even further if it feels like management has followed through in future interactions with their customer service and and laboratory personnel.

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.

From viewing their website, there's 2-labs, 10101 or 10103 building. No signs on the 10101 building indicating there's a lab. Supposedly this lab opens at 7am, but with no signage, I couldn't figure out where it is. The 10103 building is the main hospital. When I went to the main desk, the security guard was sound asleep (seriously, sound asleep). After waking him, he tells me to go to the lower level. I go to the lower level and see nothing that looks like a lab. I'm getting pissed because I purposely tried to get here before 7am. When I return to the desk, I just start asking random employees who are arriving to work. A nurse ends up helping me. She informs the security guard that I need to first register and than go to the 2nd floor lab. While I'm registering, I ask that person about the 10101 lab. She tells me that it's a separate entity. I'm convinced that this is the one I wanted because to go to the one I'm at now, I have to register as a patient, which is a hassle. The 10103 lab opens at 7:30 am.
