Hair analysis is recognized as an effective tool for identifying drug and alcohol consumption. Hair strands offer an extensive historical record of alcohol and drug usage by capturing biomarkers within the strands of growing hair. When hair is clipped close to the scalp, it can deliver a detection period extending up to around three months for alcohol and drugs. Collecting hair is straightforward, moderately resistant to tampering, and convenient for shipping.
A sample measuring 1.5 inches and consisting of approximately 200 hair strands (akin to the thickness of a #2 pencil) closest to the scalp yields 100mg of hair, which is the ideal amount for both screening and confirming results. For tests involving EtG, additional panels, or more than 10, a sample of 150mg is advised. It's suggested to measure the hair sample using a jeweler’s scale. If scalp hair is not available, a similar amount of body hair can be utilized. "Head hair" specifically refers to scalp hair, whereas "body hair" encompasses all other types (such as facial or axillary hair).
Process Overview
Key stages in the lab processing of a drug test include Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is initially processed into the laboratory's system. This step ensures the sample was properly sealed and dispatched, allocates a random LAN (Laboratory Accessioning Number), and concludes any extra data entry not included in an electronic chain of custody protocol.
Screening represents an initial rapid assessment for substances of abuse. While it offers a cost-effective method to exclude drug use for most samples, a positive result requires confirmation to be valid in a legal setting. Samples presenting a preliminary positive result during Screening necessitate further confirmation.
If a sample tests presumptively positive during Screening, more hair is taken from the original sample and readied for Extraction. In this phase, substances are extracted from hair at much lower concentrations compared to other methods (such as urine or oral fluid), leading to hair drug analysis being the most intricate method to execute.
Confirmation of a positive screen is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples testing presumptively positive undergo washing before confirmation, as required. The comprehensive lab process from Accessioning through to Confirmation is examined under both CAP (College of American Pathologists) Hair standards and ISO/IEC 17025 accreditation.
