Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. This technique captures long-term evidence of such substances by embedding biomarkers within the strands of hair as they grow. When hair is collected from near the scalp, it can reveal substance use covering up to a three-month period. The process of collecting hair samples is straightforward, challenging to tamper with, and easily transportable.
A sample measuring 1.5 inches in length, comprising around 200 hair strands (similar in thickness to a #2 pencil) close to the scalp, yields 100mg, which is optimal for both screening and confirmation tests. For EtG, additional analyses, and/or tests exceeding 10 panels, a specimen weight of 150mg is advisable. It's suggested to assess the specimen's weight using a jeweler’s scale. If scalp hair is not available, a comparable quantity of body hair may be gathered. References to head hair indicate specifically scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The primary stages in laboratory drug test processing encompass Accessioning, Screening, Extraction, and Confirmation.
Accessioning integrates a sample into the laboratory's operations. This step includes confirming the sample's proper sealing and shipping, generating a random Laboratory Accessioning Number (LAN), and finalizing any pending data entries absent from an electronic chain of custody system.
Screening serves as an initial, rapid examination for drugs of abuse. Although Screening is a cost-efficient means to preclude drug usage in most samples, any positive result necessitates confirmation to hold legal stature. Samples deemed presumptive positive during Screening require subsequent verification.
Upon a presumptive positive result in Screening, a further sample portion is extracted and processed for the Extraction phase. Here, drugs are isolated from hair at notably lower concentrations than those found in alternatives like urine or oral fluids, thus making hair drug screening the most complex methodology.
Confirmation of positive Screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples undergo washing prior to confirmation as needed. The entire laboratory procedure, spanning Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Although often termed "hair follicle tests", the analysis in fact focuses on the hair strand, not the follicle beneath the scalp.
