Within a minute, I received a text back saying, "please come in." When I entered the lab office, I did not see other patients and understood why I had to text them from my car first. I thought that was very thoughtful but probably necessary to do at a place like this where possible Corona patients visit. Fortunately, I was negative. :)

The facility has a decent sized waiting room and offers digital check in at one of the three stations in the waiting room. Checking in on the kiosk was seamless. I was called to the back a little earlier than my scheduled time and the nurse (Madison) did her thing because I have "deep" veins and it's typically an ordeal to have blood drawn but one try and BOOM all done and done pain free! I am coming back here every time I need labs done and asking for Madison.

Had to drop off something from the previous visit. The young worker with glasses and braces said it wasn't in the system and had to be emailed. Which i had to go through my online portal to find the order my doctor had sent to them. Also berated me about their system check in which ask questions about visits. However i reiterated I'm not here for a visit I'm just dropping said bag off. She then told me to wait. Another person comes to the desk and calls my name minutes later, proceeds to look at my records in her system and immediately print the lab order and say thanks that's all. There are some rude and incompetent people in the world. But if you're going to work in a field dealing with people and a company's computer system you should know how to review charts and be somewhat kind atleast.

The second time they needed to enter the orders and they had no clue what they were doing and unfortunately missed entering a basic CBC even though they drew the right tube for it so they never ran the test. Now I will have to have my blood drawn again! Also - I have great veins and it took them three sticks to get two vials of blood. This has never happened before and I am in my 60'd.

I've gotten my blood taken plenty of times, part of it is because its my job, other parts is because of check ups, blood drawns and what have you. The first person who took my sons blood was horrendous. She missed my son's vein, then started to fish the needle around. My son is 8 and on the thin side. I thought that needle was going to come out of his arm the way she was pushing and shoving it. Finally she gave up and pulled the needle out. She was going to try again and I told her no,and that i had never seen anyone move a needle that much in someone's arm. She got snippy and asked if I wanted someone else to do it. I said yes and she went to get her co worker. As she was on the other room she said that it was because my son had small veins and hadn't had alot of water. Then the other person came up, stuck the needle in and found the vein immediately. She left the needle in as she got the vials of blood she needed. No fuss, no mess. As she was filling things out she was mutterinv "oh, God!" Like I was bothering her. My next action after this is to find her manager and log a complaint.
