Hair analysis has emerged as a robust method for identifying the presence of drugs and alcohol. Hair captures a prolonged timeline of substance use by embedding indicators within the strands of hair as they grow. When taken near the scalp, hair can reveal usage history up to a roughly 3-month period for alcohol and drugs. The sample collection is straightforward, challenging to tamper with, and convenient to transport.
A 1.5-inch section comprising roughly 200 hair strands (comparable to a #2 pencil thickness) taken from near the scalp yields 100mg of hair, which is an optimal sample size for both screening and verification. For EtG, supplementary tests, and tests exceeding 10 panels, it is advised to use 150mg of the specimen. Utilizing a jeweler's scale is recommended for measuring the sample's weight. Should scalp hair not be present, a proportional quantity of body hair can be utilized. The term head hair refers specifically to scalp hair, while body hair pertains to any other type of hair (e.g., facial, axillary).
Process Overview
The laboratory processing of a drug test result encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage where the sample is incorporated into the laboratory system. This process involves confirming the sample's proper sealing and shipping, allocating a unique LAN (Laboratory Accessioning Number), and finalizing any data entries not covered by an electronic chain of custody system.
Screening involves a preliminary assessment to detect potential drug abuse. Although it is a cost-efficient method for eliminating drug usage in most samples, any positive finding needs confirmation for legal admissibility. Samples that presumptively test positive during Screening require further confirmation.
In cases of presumptive positive results during Screening, additional hair is extracted from the initial sample for the Extraction phase. In this phase, drugs are separated from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), which is why hair drug testing is notoriously complex.
Confirmation for any positive result is executed through GC/MS, GC/MS/MS, or LC/MS/MS. Samples that are presumptively positive undergo a washing process prior to confirmation if necessary. The entire laboratory operation, from Accessioning to Confirmation, is conducted under the CAP (College of American Pathologists) Hair guidelines and the ISO / IEC 17025 standards accreditation.
