Hair testing is now viewed as an effective method for identifying the use of drugs and alcohol. Hair offers a comprehensive historical record by embedding biomarkers within the hair strand's fibers as it grows. When sampled near the scalp, hair can provide a detection period of up to around 90 days for drugs and alcohol. Hair is uncomplicated to collect, challenging to tamper with, and straightforward to transport.
A 1.5-inch segment containing roughly 200 hair strands (akin to the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal quantity for routine screening and subsequent confirmation. For EtG, supplementary tests, and/or analyses exceeding 10 panels, a sample of 150mg is advisable. It is suggested to use a jeweler’s scale for weight measurement. If scalp hair isn't available, a comparable amount of body hair can be utilized. When mentioning head hair, it specifically pertains to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory analysis of a drug test result involves four principal stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the inaugural entry of a sample into a laboratory's workflow. This phase ensures that the sample was appropriately sealed and transported, allocates a random LAN (Laboratory Accessioning Number), and finalizes any missing data entry absent from an electronic chain of custody framework.
Screening represents an initial rapid evaluation for drug presence. Although Screening is an affordable method to identify drug usage across most samples, any positive indication in screening requires substantiation for legal presentation. Any samples initially deemed positive in Screening necessitate additional confirmation.
For samples indicated as positive in the Screening phase, additional hair from the original sample is prepared for Extraction. During this phase, drugs are extracted from hair at significantly lower concentrations than in other techniques (e.g., urine or oral fluid), highlighting the complexity of hair drug testing.
Confirmation of any initially positive screening is accomplished using GC/MS, GC/MS/MS, or LC/MS/MS methodologies. Each presumptively positive sample undergoes washing before confirmation as necessary. The entire lab process from Accessioning to Confirmation is scrutinized according to both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.
