i do not have health insurance. sometimes i need some lab work just to check out my cholesterol levels of other blood levels. so i can go to this business and get whatever blood test i want to get without a doctor's order or seeing a doctor first (pay cash out of pocket), and then having to see the doctor again to explain it. you just walk in and get the lab done. they can send it to you very quickly in email or longer by snail mail. the costs are about 1/4 or what it costs at other labs or hospitals. it is good to check on your own lab sometimes. no doctor required. nothing wrong with doctors, but why not just go with the results already in hand cheaper than even the doctor can do it for?!!
