I have been coming to this Lab Corp for years, and it never fails on giving great service. Every time I go I am always attended by the same young lady. She is always friendly and she is there to help you in any question you may have. Lab Corp has all the tests you can think of and they are very convenient having a lot of locations all over the Houston Area. Appointments are appreciated, but walk-ins are always welcomed. The wait time in line is not that long. Don’t go during lunch time, because they will not be there. The main reason why I give Lab Corp 3 stars is because when it comes time to pay they put your debit or credit card on file so they can take it out depending on your insurance. So you won’t know how much they will take out. I don’t like that, I want to know how much I am going to be charged. So what I do is I tell them I don’t want to be billed automatically. You can request for the bill to arrive at your house.
