I and my wife have to get labs often, and we always go to Quest Diagnostics in Mariposa, CA. The staff is wonderful there..... helpful, kind, knowledgeable, and very professional. We would recommend this business to anyone! JB Perez read more

Just super nice, super efficient and skilled personnel and service at the Mariposa location. Every single time.

We came in on a Thursday for labs. The website said they were open until four, and we scrambled to get there and made it at 3:45. We were turned away because they weren't taking any more patients for the day. So we come back in the following Monday at 11 AM, and there's a sign on the door saying they're closed for lunch from 11:30 to 12:30. So basically they're not open until four and their lunch isn't when they say it is. The employees seem to think they have a buffer zone around their business hours during which they don't have to serve patients. If you have to use this lab, call ahead before you drive all the way in to make sure they're actually there and actually seeing patients when you will be there. Their stated hours are not their actual hours. read more
