The use of hair testing has emerged as a significant approach for identifying drug and alcohol consumption. Hair is capable of offering a prolonged history of substance use by anchoring biomarkers within the hair's fibers as it grows. When obtained near the scalp, hair can present up to a roughly 3-month detection period for alcohol and drugs. It is easy to collect hair samples, challenging to tamper with, and uncomplicated to transport.
A sample size of 1.5-inch consisting of roughly 200 hair strands (equivalent to the thickness of a #2 pencil) closest to the scalp yields 100mg, ideal for both screening and verification. For EtG, additional items, or tests exceeding 10 panels, a specimen amount of 150mg is advisable. It is suggested to measure the specimen with a jeweler's scale. In the absence of scalp hair, a similar quantity of body hair may be used. References to head hair specifically allude to scalp hair. Body hair encompasses other types such as facial and axillary hair.
Process Overview
The key stages in laboratory processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial incorporation of a sample into a laboratory's workflow. This step includes ensuring the sample was correctly sealed and sent, assigning an arbitrary LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry absent from an electronic chain of custody system.
Screening consists of a preliminary swift examination for substances of abuse. Screening serves as a cost-effective technique to exclude drug use in most samples, though a positive finding demands confirmation to be legally accepted. Any samples presumed positive during Screening necessitate further confirmation.
Should a sample be regarded as presumptive positive during Screening, additional hair is retrieved from the initial sample and organized for Extraction. At this phase, drugs are extracted from hair at significantly lower concentrations than other methods (such as urine or oral fluid), underscoring the complexity of conducting hair drug screening.
Confirmation of any positive results is undertaken through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results undergo washing prior to confirmation as necessitated. The comprehensive laboratory process from Accessioning to Confirmation undergoes evaluation under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
