Hair testing is increasingly regarded as an effective method for identifying drug and alcohol consumption. By trapping biomarkers within the fibers of the growing hair strand, hair offers a retrospective view of alcohol and drug use. A sample taken near the scalp affords a detection period of roughly 3 months for alcohol and drugs. Collecting hair is straightforward, challenging to tamper with, and convenient to transport.
A sample of 1.5 inches consisting of approximately 200 hair strands, roughly equivalent to a #2 pencil's width, near the scalp provides 100mg of hair, which is the optimal amount for both screening and confirmation. For tests involving EtG, add-ons, and/or more than 10 panels, a specimen of 150mg is advised. It's recommended to measure the specimen using a jeweler’s scale. If scalp hair is not accessible, the same quantity of body hair may be collected. "Head hair" refers exclusively to scalp hair, while "Body hair" includes all other types of hair (such as facial and axillary hair).
Process Overview
There are four principal steps in the laboratory processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the preliminary processing of a specimen into a lab's system, ensuring the sample was properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing missing data entry not provided by an electronic chain of custody system.
Screening performs an initial evaluation for drugs of abuse. Although Screening is a cost-efficient method to dismiss drug usage in most cases, a positive screen needs confirmation to be validated legally. Any samples considered presumptively positive during Screening require further confirmation.
If a sample is deemed presumptively positive in the Screening phase, additional hair is extracted from the initial specimen for Extraction. At this point, drugs are separated from hair at a significantly lower concentration than in other methods (e.g., urine or oral fluid), which positions hair drug screening as the most challenging method to execute.
Positive screening results undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed before confirmation as necessary. The complete laboratory process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the accreditation according to ISO / IEC 17025 standards.
