    I walked in without an appointment 2 days before Thanksgiving at 2 pm to have some blood drawn for a metabolic panel.

    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.

    Arrived before 9am. Express check in using kiosk, iID and insurance card. Short wait. Courteous…read morestaff. Efficient service. Swift results

    Labcorp - No, what you think this sign means isn't actually what it means, per the snotty phlebotomist.

    I like this location because they don't usually have a long wait time. However, they have…read moredisappointed me because today, they totally ignored my check in. 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. She did, she was very helpful and apologized for the inconvenience. I could tell that she actually cares about her job. Thank you, Bianca for taking the time to listen and servicing me. You have earned this review another star Overall cleanliness, decent. Plenty of parking. Customer service- Juhmer has exceptional customer service skills. The older Asian lady is very rude all the time, she's always giving attitude, and is rough when withdrawing blood. Unlike Juhmer, she has left my arms bruised several times. Bianca is super nice, caring, and gentle.

    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.
