Hair screening is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair captures enduring evidence of alcohol and drug use by encasing biomarkers within the fibers of hair strands as they grow. When taken near the scalp, hair samples can offer an up to 90-day detection span for alcohol and drugs. Collecting hair is straightforward, challenging to tamper with, and simple to mail.
A 1.5-inch sample consisting of around 200 hair strands (comparable to the diameter of a no. 2 pencil) from the scalp yields 100mg of hair needed for testing and verification. For EtG, additional, and/or tests exceeding 10 panels, 150mg of the sample is preferred. It's advisable to weigh the hair using a jeweler’s scale. If scalp hair isn’t available, an equivalent quantity of body hair is adequate. 'Head hair' refers only to scalp hair, whereas 'body hair' includes all other varieties (facial, axillary, and so on).
Procedure Synopsis
The lab processing of drug test outcomes encompasses four fundamental stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning signifies the preliminary handling of a sample within a lab's framework. This stage assures that the sample was securely sealed and correctly sent, assigns a unique LAN (Laboratory Accessioning Number), and addresses any outstanding data entry missed by an electronic chain-of-custody mechanism.
Screening provides an initial rapid assessment for illicit substances. Though cost-effective for excluding drug use in most samples, a positive screen demands confirmation for legal admissibility. All samples that show a presumptive positive upon Screening necessitate a confirmatory check.
For any Screening-identified presumptive positives, more hair is extracted from the initial sample and readied for Extraction. In this phase, drugs are isolated from hair at markedly lower concentrations compared to methods like urine or oral fluid, rendering hair drug screening among the most arduous methods.
Positive screens receive confirmation using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positives are cleansed as required prior to confirmation. The totality of the lab procedure from Accessioning through Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the accreditation standards of ISO / IEC 17025.
