Hair analysis has emerged as a robust method for uncovering drug and alcohol consumption. Hair retains a long-standing record of alcohol and other substances by embedding biomarkers within the strands of growing hair. Collected near the scalp, hair can offer a detection period of up to about 90 days for alcohol and other drugs. It's easy to gather, moderately challenging to tamper with, and straightforward to transport.
A segment of hair measuring 1.5 inches, roughly 200 strands (similar to the thickness of a #2 pencil) nearest to the scalp, provides 100mg of hair, which is the ideal amount for both initial testing and confirmation. For EtG, extra assessments, and/or tests exceeding 10 panels, 150mg of the sample is advisable. It's beneficial to weigh the sample using a jeweler’s scale. If scalp hair isn't available, a similar quantity of body hair can be collected. When we mention head hair, it specifically refers to scalp hair, while body hair pertains to all other hair types (facial, axillary, etc.).
Process Overview
The fundamental procedures in laboratory drug testing consist of Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the preliminary processing of a sample into the lab’s database. This step includes checking that the sample was adequately sealed and shipped, assigning a distinctive LAN (Laboratory Accessioning Number), and completing any leftover data entry not handled by an electronic chain of custody system.
Screening is a rapid initial assessment for drugs of abuse. Screening is a budget-friendly method to dismiss drug usage in most samples, yet a positive result requires confirmation to be valid in a legal setting. Any samples that suggest positivity in Screening must undergo secondary confirmation.
Should a sample show presumptive positivity during Screening, additional hair is extracted from the original sample for the Extraction process. Here, drugs are derivable from hair at notably lower concentrations compared to other methodologies (e.g., urine or oral fluid), which makes hair drug analysis the most challenging methodology to execute.
Confirmation of any screening result indicating positivity is completed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that suggest positivity undergo a washing process prior to confirmation as necessary. The complete lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair classification and accreditation according to ISO / IEC 17025 standards.
