Hair analysis is recognized as an effective method for identifying drug and alcohol usage. Hair retains a prolonged record of substances by trapping biomarkers within the fibers of the strand as it grows. Sampling close to the skull allows hair to deliver a detection period of up to around 90 days for alcohol and drugs. Collecting hair is straightforward, hard to tamper with, and convenient to transport.
A sample of 1.5 inches from approximately 200 strands near the scalp (roughly matching the thickness of a #2 pencil) will provide 100mg, which is the optimum sample size for screening and confirmation. For testing specifics like EtG, add-ons, or tests exceeding 10 panels, 150mg of hair is suggested. It is advisable to measure the sample with a jeweler's scale. Should scalp hair be unavailable, the same quantity of body hair can be utilized. References to head hair pertain solely to scalp hair. Body hair encompasses all other hair types (such as facial, axillary, etc.).
Process Overview
The laboratory analysis of a drug test result involves four crucial steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage where the sample is introduced into a laboratory’s system. This step involves confirming that the sample was sealed and transported correctly, generating a random Laboratory Accessioning Number (LAN), and finalizing any necessary data entry not supplied by an electronic chain of custody system.
Screening is the initial rapid evaluation for substance abuse. Although it is a cost-effective approach to rule out drug use on most samples, confirmation is needed for any positive screening to hold legal weight. Samples that test presumptively positive in Screening must undergo additional confirmation.
In scenarios where a sample tests presumptively positive during Screening, additional hair is extracted from the primary sample for further preparation during Extraction. In this procedure, drugs are extracted at significantly lower concentrations than in other methods like urine or oral fluid testing, making hair drug screening a challenging process.
Validation of a positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation if necessary. The comprehensive laboratory process from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
