Hair examinations are recognized as an effective approach for identifying drug and alcohol consumption. Hair strands capture biomarkers within their fibers, offering a prolonged record of substance use. When obtained from the scalp's vicinity, hair can provide a detection period of up to about three months for alcohol and drugs. Collecting hair is straightforward, challenging to tamper with, and easily transportable.
A hair sample measuring 1.5 inches, consisting of roughly 200 strands resembling the width of a #2 pencil, yields 100mg, which is the optimal quantity for analysis and verification. For EtG, additional tests, or panels exceeding 10, a 150mg sample is advisable. Utilizing a jeweler’s scale for weighing the sample is advised. If scalp hair is inaccessible, an equal quantity of body hair is a viable alternative. The term head hair pertains solely to scalp hair, whereas body hair includes all other types such as facial and axillary hair.
Process Overview
The laboratory processing of a drug test result comprises four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a sample into the laboratory’s system. This ensures the sample's correct sealing and shipment, allocates a random LAN (Laboratory Accessioning Number), and completes additional data entries not covered by electronic custody systems.
Screening involves an initial rapid assessment for drugs of abuse. Although it’s a cost-efficient means to exclude drug usage in most samples, any positive screen requires further confirmation to be legally accepted. Samples yielding presumptive positive results in Screening necessitate a secondary verification.
In cases of presumptive positive outcomes during Screening, more hair is extracted from the initial specimen for the Extraction phase. In this step, drugs are extracted from hair at much lower concentrations compared to other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.
GC/MS, GC/MS/MS, or LC/MS/MS techniques carry out the Confirmation of any positive screening outcome. Presumptive positive samples undergo washing prior to Confirmation as required. The entire laboratory procedure, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards' accreditation.
