Hair analysis is now acknowledged as an effective means for detecting the usage of drugs and alcohol. By capturing biomarkers within the strands, hair offers an extended timeline of alcohol and drug usage. When taken near the scalp, hair offers up to a three-month detection range for substances. Hair is straightforward to obtain, relatively tamper-proof, and simple to transport.
A sample of hair measuring 1.5 inches from about 200 strands (akin to a #2 pencil's thickness) provides 100mg, which is the preferred amount for testing and validation. For tests like EtG, additional tests, or those exceeding 10 panels, 150mg is advised. It's suggested to weigh the sample on a jeweler’s scale. If hair from the scalp is not accessible, an equal quantity of body hair can be used. In mentioning head hair, it refers solely to scalp hair, while body hair includes hair from other areas (face, axillary, etc.).
Process Overview
The procedure for processing a drug testing result in a lab involves four main steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary stage where a sample is processed into the laboratory’s system. This entails checking that the sample is sealed and shipped correctly, allocating a random LAN (Laboratory Accessioning Number), and completing any necessary data entry not facilitated by an electronic chain of custody system.
Screening is a preliminary and efficient method to check for drug abuse. While it is a cost-effective way to exclude drug use for most samples, a positive screening must be confirmed to be valid in a legal setting. All samples screened as presumptively positive require follow-up confirmation.
For samples with presumptive positive results in Screening, additional hair is extracted from the original sample and prepared for Extraction. At this phase, drugs are extracted from hair at significantly lower concentrations than other methods (e.g., urine or oral fluids), presenting hair drug screening as the most intricate methodology.
Confirmation of any positive screening result is done through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation when needed. The end-to-end laboratory procedure from Accessioning to Confirmation is monitored in accordance with both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards.
