The assessment of hair has emerged as an effective method to uncover drug and alcohol consumption. Hair enables a comprehensive archive of substance use by encapsulating biomarkers in its fibers as it grows. When sampled near the scalp, it can offer a detection period of up to roughly three months for substances. Hair collection is straightforward, relatively tamper-proof, and easy to transport.
A sample of hair measuring 1.5 inches containing roughly 200 strands (comparable to the girth of a #2 pencil) nearest to the scalp yields 100mg, which is the optimal quantity for testing. For EtG, additional tests, and/or analysis exceeding 10 panels, 150mg is advised. We endorse using a jeweler’s scale to measure the sample. If scalp hair is absent, a proportionate quantity of body hair can be used. When mentioning head hair, it refers to scalp hair exclusively, while body hair encompasses any other hair type (facial, axillary, etc.).
Process Overview
The drug testing procedure in a lab encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the preliminary intake of a sample into a laboratory's records. This process verifies the sample's proper sealing and shipping, assigns a unique LAN (Laboratory Accessioning Number), and finalizes any pending data entry absent in an electronic custody chain system.
Screening administers an initial, swift evaluation for substances. Although cost-efficient for discounting drug presence in most instances, a positive screen necessitates confirmation for legal validity. Samples that are prescreen positive in Screening mandate an additional confirmation.
Should Screening yield a presumption of positivity, additional hair is extracted from the original sample for the Extraction phase. Here, the drugs are extracted from hair at significantly lower concentrations than alternative methods (such as urine or oral fluid), which is why hair drug testing poses a considerable challenge.
Positive screening outcomes are verified by means of GC/MS, GC/MS/MS, or LC/MS/MS. All prescreen positive samples undergo cleaning as required before confirmation. The entire lab protocol from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
