How long does it take to get hair analysis results after the sample reaches the laboratory?
A. Obviously, accuracy comes before speed. In addition, hair comes to the laboratory in solid form and requires additional and manual sample preparation as part of the testing process. APL’s turnaround time from receipt of the hair sample in the laboratory is approximately 24 – 72 hours. Occasionally, the laboratory will require some additional time to work with a difficult sample. If a retest is requested by a client, that sample will be subjected to more sensitive analysis and will require approximately one week of laboratory time.
