Hair analysis has emerged as a formidable means for identifying drug and alcohol consumption. By embedding biomarkers in the strands of advancing hair, it offers an extended timeline of alcohol and drug usage. When sourced near the scalp, hair can reveal drug and alcohol intake for up to roughly a 3-month duration. Hair is straightforward to gather, somewhat resistant to tampering, and simple to transport.
A sample of 1.5 inches, made up of around 200 hair strands (similar in size to a #2 pencil) from the scalp, yields 100mg of hair, which is ideal for screening and verification. For EtG, additional tests, or tests exceeding 10 panels, 150mg of the sample is advised. It's advisable to weigh the hair sample using a jeweler’s scale. If scalp hair can't be obtained, an equivalent amount of body hair can be utilized. References to head hair pertain strictly to scalp hair, whereas body hair includes all other types (facial, axillary, etc.).
Process Overview
The key steps in laboratory processing for a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of incorporating a sample into the lab's system. It ensures the sample was properly sealed and delivered, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data entry that isn’t available from an electronic chain of custody system.
Screening performs a preliminary examination for drugs of abuse. While it is a cost-effective approach to eliminate drug use in most samples, positive results require confirmation to be permissible in legal proceedings. Samples that test as presumptively positive in Screening need a secondary confirmation.
For samples presuming positive in Screening, more hair is extracted from the original sample for the Extraction phase. Here, drugs are isolated from hair at a substantially lower concentration than in alternative methods (e.g., urine or oral fluid), making hair drug screening the most intricate method to conduct.
Positive screening outcomes are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed as necessary before confirmation. The complete laboratory workflow, from Accessioning to Confirmation, is evaluated under the CAP (College of American Pathologists) Hair category and accreditation to ISO / IEC 17025 standards.
