Hair testing has emerged as an effective mechanism for identifying drug and alcohol consumption. Hair captures biomarkers in the growing strand's fibers, offering an extended history of substance use. Collected near the scalp, it can indicate drug and alcohol use over roughly three months. Hair is straightforward to collect, challenging to tamper with, and simple to transport.
A sample of 1.5 inches consisting of about 200 hair strands (equivalent to the size of a #2 pencil) near the scalp measures around 100mg, the ideal quantity for screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, a specimen of 150mg is advisable. It is recommended to measure the specimen on a jeweler’s scale. When scalp hair is not available, a similar amount of body hair may be taken. 'Head hair' refers exclusively to scalp hair, whereas 'body hair' includes all other hair forms (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result pivots around four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning signifies the initial incorporation of a sample into a lab's framework. This involves validating the sample’s proper sealing and transportation, assigning a random LAN (Laboratory Accessioning Number), and completing any supplemental data entry absent from an electronic chain of custody system.
Screening constitutes a preliminary swift assessment for substances of abuse. Although Screening offers a cost-effective route for dismissing drug usage in many samples, a positive screen necessitates confirmation for legal validity. Samples that test presumptively positive in the Screening stage demand additional confirmation.
If a sample tests presumptively positive during Screening, additional hair is extracted from the primary specimen for Extraction. At this juncture, drugs are separated from hair at a markedly lower concentration than other methods (e.g., urine or oral fluid), rendering hair drug screening the most challenging methodology.
Confirmation of any presumptively positive screen is performed through GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as required. The complete laboratory process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
