A member asked:

How long do drug test results take?

A doctor has provided 1 answer

Depends on the drug : And purpose of the test. Most drugs used in treatment of common illnesses are routinely tested by hospital labs and results are usually available in four hours or sooner. Tests done for medico-legal purposes require confirmation and may take a day or two. Uncommonly used drugs may need to be sent to a reference lab and take a few days.
