Hair analysis is increasingly regarded as a potent means for identifying drug and alcohol consumption. By capturing biomarkers within the fibers of the growing hair strand, hair offers a comprehensive history of alcohol and drug intake. When obtained near the scalp, hair can reveal drug and alcohol use for a duration of up to three months. Hair is straightforward to collect, relatively challenging to tamper with, and convenient to transport.
A sample measuring 1.5 inches, consisting of approximately 200 strands (similar to the diameter of a #2 pencil) closest to the scalp, provides 100mg of hair, which is the optimal amount for testing and confirming results. For tests exceeding 10 panels, EtG, or additional assessments, 150mg of hair is advised. It's recommended to use a jeweler’s scale to weigh the sample. Should scalp hair be absent, an equivalent quantity of body hair may be utilized. 'Head hair' specifies only scalp hair, while 'body hair' encompasses all other hair types, such as facial and axillary hair.
Process Overview
Drug test processing in laboratories involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial entry of a sample into a laboratory’s system. This step includes tasks like ensuring the sample was properly sealed and transported, assigning a Laboratory Accessioning Number (LAN) at random, and completing any remaining data entry not managed by an electronic chain of custody framework.
The Screening stage involves a preliminary check for drug presence. Although Screening is a cost-efficient technique to dismiss drug use across many samples, any positive screen requires confirmation for legal proceedings. Samples with presumptive positive results in Screening necessitate further verification.
If a sample is tentatively positive in Screening, additional hair is taken from the original sample and prepared for Extraction. This phase involves extracting drugs from hair at much lower concentrations than other methods, like urine or oral fluid, which is why hair testing is more complex.
For results confirmation, they are analyzed using techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed before confirmation when necessary. The entire lab process from Accessioning to Confirmation is scrutinized under the CAP’s Hair designation and accredited according to ISO / IEC 17025 standards.
