Hair testing is recognized as a potent method for detecting drug and alcohol consumption. By embedding biomarkers within the fibers of the hair strand during growth, hair offers an extended history of substance usage. Collected near the scalp, hair provides a detection timeframe of up to nearly three months for alcohol and other drugs. It's easy to collect, hard to alter, and simple to transport.
A sample of 1.5 inches, consisting of approximately 200 hair strands—similar to a #2 pencil's width—yields 100mg, the perfect sample size for analysis and verification. For EtG, additional tests, or tests exceeding 10 panels, a 150mg sample is advisable. Using a jeweler’s scale is recommended for specimen weighing. In the absence of scalp hair, an equivalent portion of body hair can be used. Head hair strictly refers to scalp hair, whereas body hair includes any other types (facial, axillary, etc.).
Process Overview
The drug test laboratory processing encompasses four critical steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the sample's initial handling in the lab's system. Tasks include confirmation of proper sample sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any necessary data entry if not covered by an electronic chain of custody system.
Screening provides a preliminary check for substances of abuse. Although cost-effective for negating drug use across most samples, any positive screen must be confirmed for legal acceptance. Presumptively positive samples in Screening require further confirmation.
If the Screening phase suggests a positive result, extra hair from the original sample is taken for Extraction. In this process, drugs are pulled from hair at a much lower concentration than other techniques (such as urine or oral fluid), presenting why hair drug screening is a complex procedure to conduct.
Confirmation of any positive results from Screening is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples deemed presumptively positive undergo washing before confirmation if necessary. The entire process, from Accessioning to Confirmation, is conducted according to the CAP (College of American Pathologists) Hair designation and accreditation under ISO / IEC 17025 standards.
