Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair contains a long-term record of alcohol and drug use by embedding biomarkers in the strands as they grow. When harvested close to the scalp, hair offers a detection period of up to roughly three months for alcohol and other substances. Hair is straightforward to gather, challenging to tamper with, and simple to transport.
A 1.5-inch section comprising around 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, an ideal quantity for both screening and verification. For EtG, additional tests, or analyses exceeding 10 panels, 150mg of the sample is advised. We suggest using a jeweler’s scale to weigh the specimen. If scalp hair cannot be obtained, the equivalent amount of body hair can be used. When discussing head hair, we solely mean scalp hair, whereas body hair refers to any other types (facial, axillary, etc.).
Process Overview
The laboratory handling of a drug test result involves four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers the initial handling of a sample within a laboratory’s system. This step ensures that the sample is properly sealed and shipped, assigns a unique LAN (Laboratory Accessioning Number), and completes any extra data entry not facilitated by an electronic chain of custody mechanism.
Screening performs a preliminary rapid check for drug abuse. While Screening is a budget-friendly way to eliminate drug usage in the majority of samples, a positive screen must be verified to hold up in court. Samples that are tentatively positive in Screening require a secondary validation.
If Screening indicates a presumptive positive, additional hair is collected from the specimen and readied for Extraction. At this point, drugs are isolated from hair at significantly lower concentrations than through other techniques (such as urine or oral fluid), underscoring why hair drug screening is a challenging methodology to carry out.
Confirmation of any positive results from Screening is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples receive washes prior to confirmation as required. The whole laboratory operation from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Note: Though commonly known as "hair follicle tests", the analysis is performed on the hair strand rather than the hair follicle below the scalp.
