Hair analysis is now regarded as an effective method for detecting drug and alcohol consumption. By capturing biomarkers within the fibers of the developing hair, it offers a lengthy record of alcohol and substance use. When taken from near the scalp, hair can offer a detection period of up to about 90 days for alcohol and substances. Hair is easy to gather, less prone to tampering, and straightforward to transport.
A sample of 1.5 inches consisting of roughly 200 hair strands (approximately the width of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the preferred quantity for analysis and verification. For EtG, additional tests, or panels exceeding 10, a 150mg sample is advised. It’s suggested to measure the sample with a jeweler’s scale. If scalp hair cannot be used, an equivalent quantity of body hair can be collected. When mentioning head hair, it pertains specifically to scalp hair. Body hair denotes all other types (such as facial or underarm hair).
Process Overview
There are four primary steps in the lab processing for drug test analysis: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into the lab’s system, including checking if the sample was properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any further data recording not handled by an electronic chain of custody system.
Screening is an initial rapid assessment for substances of misuse. While cost-effective for excluding drug consumption on most samples, a positive screen must be confirmed to be valid in legal settings. Samples indicative of positive results in Screening require a subsequent confirmation.
If a sample tests preliminary positive during Screening, more hair is extracted from the initial sample and readied for Extraction. Here, substances are derived from hair at significantly lower concentrations than through other means (such as urine or saliva), which accounts for the complexity of hair drug analysis.
Confirmation of a positive screen result is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating positive results are cleansed prior to confirmation when necessary. The complete lab process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
