In the realm of detecting drug and alcohol consumption, hair testing is regarded as a valuable tool. By capturing biomarkers within the strands of hair, a long-term record of substance use can be observed. Hair collected near the scalp can reveal up to a 90-day detection period for various substances. The process of collecting hair is straightforward, presents challenges to tampering, and is uncomplicated to transport.
A 1.5-inch portion consisting of roughly 200 strands of hair (comparable to a #2 pencil) near the scalp provides a sample of 100mg, which is optimal for testing and confirming results. For EtG, additional screenings, or tests exceeding 10 panels, 150mg of hair is advised. It is suggested to weigh the hair sample using a jeweler’s scale. If scalp hair isn't available, a similar amount of body hair can be used. "Head hair" pertains specifically to scalp hair, whereas "body hair" encompasses all other hair types (like facial or axillary).
Process Overview
The laboratory process of a drug test outcome is composed of four primary phases: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially processed into the laboratory’s system. This involves confirming proper sealing and shipping of the sample, generating a random LAN (Laboratory Accessioning Number), and entering any supplementary data not covered by an electronic chain of custody system.
Screening serves as an initial assessment for substances of abuse. While it is a cost-effective measure for ruling out the majority of samples, positive screenings need further validation to be legally valid. All samples yielding presumptively positive results in Screening necessitate additional confirmation.
In scenarios where a sample tests presumptively positive during Screening, additional hair is taken from the initial sample and prepped for Extraction. At this stage, drugs are extracted from hair at significantly lower concentrations than other methods (such as urine or oral fluid), making hair drug screening a challenging methodology to execute.
Positive screening results undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples are washed before confirming if necessary. The end-to-end laboratory process, spanning from Accessioning to Confirmation, is assessed under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Although sometimes called "hair follicle tests", it is the hair shaft, rather than the follicle beneath the scalp, that is examined.
