Hair testing stands as an effective method for identifying drug and alcohol consumption. Hair captures extended histories of alcohol and drug exposure by embedding biomarkers within the strands as they grow. When collected near the scalp, hair samples can offer up to a roughly 90-day detection period for drugs and alcohol. Collection is straightforward, resistance to tampering is higher, and transportation is uncomplicated.
A sample consisting of 1.5 inches from about 200 hair strands (around the width of a #2 pencil) nearest the scalp will yield 100mg of hair, which is optimal for screening and confirmation tests. For EtG, additional tests, or tests exceeding 10 panels, a sample size of 150mg is preferable. It's suggested to weigh the sample using a jeweler's scale. In cases where scalp hair isn't available, a comparable quantity of body hair may be used. Reference to head hair involves scalp hair exclusively. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The procedure utilized by labs to process a drug test includes: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves incorporating a sample into the lab's system. This step includes ensuring proper sealing and shipping of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing any remaining data entry not covered by an electronic chain of custody system.
Screening is a preliminary fast check for controlled substances. Although it is an economical method to exclude drug use on most samples, a positive result necessitates confirmation for legal admissibility. Any samples hinted to be positive in Screening necessitate a secondary verification.
Should a sample show a presumptive positive in Screening, additional hair is extracted from the initial sample for further preparation in the Extraction phase. During this phase, drugs are isolated from hair at concentrations significantly lower than those in other processes (e.g., urine or oral fluid), which is why hair drug testing is considered the most challenging methodology to execute.
Positive Screening results are confirmed via GC/MS, GC/MS/MS, or LC/MS/MS. All preliminarily positive samples undergo washing before confirmation as required. The entire lab processing from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.

Note: Often termed as "hair follicle tests", the actual analysis is conducted on the hair strand, not the follicle beneath the scalp.
