Hair analysis is recognized as an effective means for identifying alcohol and drug usage. Hair can record a prolonged timeline of drug and alcohol presence by embedding biomarkers within its growing strands. Collected near the scalp, hair offers up to an approximate three-month detection span for both alcohol and drugs. Its easy collection process, resistance to tampering, and simple shipping make hair an ideal sample.
A 1.5-inch section of around 200 hair strands (comparable to the thickness of a #2 pencil) from the scalp results in 100mg, which is ideal for testing. For EtG, additional tests, or those exceeding 10 panels, 150mg is advised. It is suggested to weigh the hair on a jeweler's scale. If scalp hair can't be collected, an equivalent amount of body hair is viable. When mentioning head hair, it specifically refers to scalp hair, while body hair covers all other types (such as facial or axillary).
Process Overview
The laboratory drug test processing incorporates four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage of integrating a sample into the lab’s system, involving the verification of sealed and correctly shipped samples, the assignment of a random LAN (Laboratory Accessioning Number), and completing any needed data entry beyond what an electronic chain of custody system supplies.
Screening is a preliminary examination for drugs of abuse. Although it is cost-efficient for eliminating drug use in most samples, a positive outcome requires confirmation for legal admissibility. All samples suspected positive in Screening must undergo secondary confirmation.
If Screening suggests a positive result, additional hair is used from the initial sample for Extraction. This phase extracts drugs from hair at markedly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug testing the most challenging to conduct.
Confirmation of a positive screening result is completed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing before confirmation when necessary. The entire testing process from Accessioning to Confirmation is under review following both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.
