Hair testing is increasingly recognized as an effective method for detecting drug and alcohol consumption. Hair captures a long-term record of alcohol and drug use by embedding biomarkers within the hair fiber during growth. A sample collected near the scalp can reveal a drug history of up to three months. Hair collection is straightforward, resistant to tampering, and simple to transport.
To obtain the ideal sample for both screening and confirmation, a 1.5-inch section of roughly 200 hair strands (similar to the thickness of a #2 pencil) yielding 100mg is necessary. For EtG, additional testing, and panels exceeding 10, a 150mg specimen is advised. Using a jeweler’s scale to weigh the sample is recommended. If scalp hair is unavailable, a similar amount of body hair can be used. When discussing head hair, we refer only to scalp hair. Body hair encompasses all other types of hair (such as facial, axillary, etc.).
Process Overview
The four crucial stages in the laboratory processing of a drug test are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the first entry of a sample into a laboratory's records. This step ensures the sample is sealed and shipped correctly, assigns a LAN (Laboratory Accessioning Number) randomly, and completes any missing data entry not covered by an electronic chain of custody system.
Screening provides a preliminary and rapid evaluation for drug presence. Although a cost-effective method for ruling out drug usage in most cases, a positive screen must be verified to be valid in legal situations. All presumptive positive samples detected in Screening require further confirmation.
For samples testing positive in the Screening phase, additional hair from the original sample is used for Extraction. Drugs are extracted at much lower concentrations from hair than from samples such as urine or oral fluids, which is why hair testing is one of the most challenging methods.
Positive results from Screening are confirmed using methods like GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleaned before confirmation if needed. The comprehensive laboratory procedure, from Accessioning to Confirmation, is evaluated based on both CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.

Note: Although commonly called "hair follicle tests," it's important to note that the analysis is performed on the hair strand, not the follicle beneath the scalp.
