Hair testing is acknowledged as an effective method for identifying drug and alcohol usage. Hair captures long-term evidence of such substances by embedding biomarkers within the hair shaft. When sampled near the scalp, hair can reveal drug and alcohol usage history up to a 90-day period. Hair collection is straightforward, difficult to tamper with, and simple to dispatch.
A sample size of 1.5 inches, made up of approximately 200 hair strands (comparable to a #2 pencil's thickness), equates to 100mg, the optimal volume for both screening and confirmation. For multiple panel tests exceeding 10 panels and EtG, 150mg is advised. It is recommended to weigh the specimen using a jeweler’s scale. If scalp hair isn't available, an equivalent mass of body hair can be collected. Head hair strictly denotes scalp hair, while body hair encompasses every other hair type (including facial and axillary hair).
Process Overview
The laboratory process for processing a drug test encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning incorporates the initial integration of a sample into the laboratory's database, which involves confirming the sample's proper sealing and shipment, generating a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data required outside of an electronic chain of custody system.
Screening offers a preliminary analysis for drug presence. Screening is an affordable technique to rule out drugs in most samples, but a positive screen mandates further validation for legal acceptability. Samples that screen as preliminarily positive necessitate confirmatory testing.
Should a sample screen as positive, further hair is retrieved from the original sample for the Extraction phase. Here, drug compounds are isolated from hair at much lower concentrations than found in other forms such as urine or oral fluids, making hair drug analysis the most intricate procedure to conduct.
Verification of any positive screening is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before the confirmation process, as applicable. The entire analytical workflow, from Accessioning to Confirmation, is scrutinized under both the CAP's (College of American Pathologists) Hair certification, and ISO / IEC 17025 accreditation standards.
