Hair tests are increasingly considered an effective means for identifying drug and alcohol use. Hair captures a long-term record of alcohol and drug consumption by embedding biomarkers within the fibers of the hair as it grows. When sampled near the scalp, hair can offer a detection timeframe of up to roughly 3 months for alcohol and drugs. Hair is easy to gather, challenging to alter, and convenient to transport.
A 1.5-inch section of around 200 hair strands (approximately the thickness of a #2 pencil) closest to the scalp yields 100mg, the optimal sample size for both screening and verification. For EtG, additional tests, and those beyond 10 panels, a sample of 150mg is advised. We suggest using a jeweler’s scale to measure the specimen. If scalp hair is not available, an equivalent quantity of body hair can be used. In our context, head hair refers specifically to scalp hair, while body hair encompasses all other hair types (e.g., facial, axillary).
Process Overview
The laboratory processing of a drug test consists of four main phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first step where a sample is processed into a lab's system. This includes ensuring the sample was properly sealed and dispatched, assigning it a random LAN (Laboratory Accessioning Number), and completing any additional data entry not automated by an electronic chain of custody system.
Screening involves a preliminary swift assessment for drugs of abuse. It is a cost-efficient method to exclude drug usage in most samples, but any positive results from Screening must be confirmed to be valid in legal settings. Any samples suspected to be positive in Screening necessitate a further confirmation.
Should a sample be presumed positive during the Screening phase, additional hair is extracted from the initial sample and prepared for Extraction. In Extraction, drugs are isolated from hair at much lower concentrations than alternative methods (like urine or oral fluids), which makes hair drug screening one of the most challenging methodologies.
Any positive screening outcome is verified through GC/MS, GC/MS/MS, or LC/MS/MS. Presumably positive samples undergo washing before confirmation if necessary. The entire lab procedure from Accessioning through Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the standards set by ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: While often termed as "hair follicle tests", the analysis is performed on the hair strand itself and not the follicle beneath the scalp.
