Hair testing has grown into an essential mechanism for identifying drug and alcohol consumption. Hair fibers capture biomarkers along the strand, offering an extended history for alcohol and drug use. When clipped near the scalp, hair can reveal alcohol and drug use within roughly a 90-day period. Hair sampling is easy to gather, moderately tough to tamper with, and simple to dispatch.
A section measuring 1.5 inches of roughly 200 hair strands (similar to the thickness of a #2 pencil) close to the scalp will produce 100mg of hair, optimal for both screening and corroboration. For tests involving EtG add-ons and/or exceeding 10 panels, 150mg of the sample is advisable. It's best to measure the sample on a jeweler’s scale. If scalp hair can’t be sourced, an equal amount of body hair can be used. When mentioning head hair, it pertains only to scalp hair. Body hair indicates all other types (facial, axillary, etc.).
Process Overview
The core steps involved in lab processing of drug test results are Accessioning, Screening, Extraction, and Confirmation.
Accessioning constitutes the preliminary handling of a specimen into a lab’s system. This encompasses verifying the sample was properly sealed and sent, assigning a unique LAN (Laboratory Accessioning Number), and completing additional data entry absent from an electronic chain of custody system.
Screening acts as a primary swift evaluation for potential drug use. While Screening is an economical means to dismiss drug use in most specimens, positive screenings require confirmation for legal acceptability. Any specimens testing positive in Screening necessitate secondary validation.
If a specimen tests positive in the Screening phase, further hair is extracted from the initial sample and readied for Extraction. Here, drugs separate from hair at significantly lower concentrations than in other methods (such as urine or oral fluid), which is why hair drug screening poses a high level of difficulty.
Confirmation of any positive screening outcomes is carried out by GC/MS, GC/MS/MS or LC/MS/MS. Presumptively positive samples undergo washing before confirmation as necessary. The comprehensive lab process from Accessioning to Confirmation undergoes scrutiny under CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
