At Any Lab Test Now, a medical-testing facility replete with a CLIA-certified laboratory, patients typically wait for no more than 15 minutes to see a staffer and receive a blood, DNA, STD, or drug test. The tests don't require prescriptions or doctors' approvals, and patients usually receive the confidential results within 48 hours. They can decide how they’d like to receive the results—whether by pickup, email, snail mail, or fax from the future.
