LabTest MD, Atlanta

LabTest MD’s team screens patients for allergies, STDs, paternity status, and even steroid use—overall, it offers more than 2,000 medical tests. A CLIA-certified lab processes each one and typically releases the results in 72 hours or less. As at a doctor’s office, test results are confidential; however, unlike at a doctor’s office, patients have complete control over which tests they undergo.
