Hair testing has gained recognition as an effective method for identifying drug and alcohol usage. The hair captures a comprehensive history of drug and alcohol presence by embedding markers in its growing fibers. By collecting hair near the scalp, it can offer a detection period of up to roughly 90 days for alcohol and drugs. Hair collection is straightforward, relatively tamper-resistant, and easy to send.
A section of 1.5 inches consisting of around 200 hair strands (similar to a #2 pencil size) nearest to the scalp will provide 100mg of hair, which is the perfect amount for both screening and validation. For EtG add-ons or assessments beyond 10 panels, a 150mg sample is advised. Using a jeweler’s scale for weighing the hair sample is suggested. If scalp hair can't be used, a comparable quantity of body hair may be collected instead. The term head hair specifically refers to scalp hair, while body hair includes all other hair types (such as facial, axillary, etc.).
Process Overview
The key stages in processing a drug test result in the lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first stage where a sample is entered into a laboratory’s system. This stage checks that the sample was sealed and sent correctly, assigns a unique LAN (Laboratory Accessioning Number), and enters any additional data not included in an electronic chain of custody system.
Screening serves as an initial rapid check for drug abuse. Although screening is a cost-efficient way to negate drug use in most samples, a positive screen must be validated for legal acceptability. Any samples that show a presumptive positive in Screening must undergo a secondary confirmation.
Should a sample indicate a presumptive positive during Screening, extra hair is retrieved from the original sample for the Extraction process. Here, drugs are isolated from hair at substantially lower concentrations than other methods (like urine or oral fluid), establishing hair drug screening as a notably challenging procedure.
Confirmation of any positive screening outcome utilizes GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation as necessary. The complete lab process from Accessioning to Confirmation undergoes evaluation under both the CAP (College of American Pathologists) Hair designation and accreditation according to ISO/IEC 17025 standards.
