The use of hair testing has become recognized as an effective method for identifying drug and alcohol consumption. As hair grows, it captures biomarkers of alcohol and drugs, providing a comprehensive long-term history. When collected near the scalp, hair can reflect alcohol and drug usage over a period of up to 3 months. It is easy to collect, relatively hard to tamper with, and straightforward to transport.
A sample consisting of about 200 strands of hair, cutting to 1.5 inches from the scalp (roughly the thickness of a #2 pencil), amounts to 100mg, which is considered optimal for preliminary screening and verification. For tests including EtG, additional specifications, or panels exceeding 10, a 150mg sample is preferred. Utilizing a jeweler’s scale for measurement is advisable. If scalp hair is inaccessible, a comparable amount of body hair can be collected. The term head hair specifically refers to scalp hair, while body hair encompasses all other types (e.g., facial, axillary).
Process Overview
The laboratory processing of a drug test result entails four primary stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially processed into a laboratory's system. This process ensures that the sample was correctly sealed and shipped, assigns a unique LAN (Laboratory Accessioning Number), and includes any additional data entry absent from an electronic chain of custody system.
Screening is the initial rapid assessment for drugs of abuse. Although cost-efficient for negating drug usage in most samples, a positive screen must undergo confirmation to stand up in court. Any samples preliminarily positive at this stage need secondary confirmation.
In cases where the Screening stage yields a presumptive positive, additional hair is taken from the original sample and prepared for Extraction. Here, drugs are isolated from hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening compared to other methodologies.
Confirmation of any positive screening outcome is executed through GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples are cleansed as necessary. The comprehensive laboratory process, spanning from Accessioning to Confirmation, is evaluated under the CAP (College of American Pathologists) Hair directive and accreditation according to ISO / IEC 17025 criteria.
