Hair tests have become an effective means for identifying drug and alcohol usage. Hair records a prolonged history of substance use by embedding biomarkers in the fibers of the hair as it grows. When collected near the scalp, hair offers up to a 3-month detection period for alcohol and substances. Collection is straightforward, challenging to tamper with, and simple to transport.
A sample measuring 1.5 inches and containing approximately 200 hair strands (equivalent to a #2 pencil) from the scalp yields 100mg, the optimal quantity for screening and confirmation. For EtG, additional tests, or tests over 10 panels, 150mg of the sample is suggested. It's advisable to weigh the specimen with a jeweler’s scale. If scalp hair isn't available, a similar quantity of body hair can be collected. References to head hair specifically mean scalp hair. Body hair includes other varieties (facial, armpit, etc.).
Process Overview
The procedure for analyzing drug test results in a laboratory includes Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the phase where a sample is initially processed into the laboratory system. It entails ensuring the sample was sealed and delivered correctly, allotting a random LAN (Laboratory Accessioning Number), and filling in any additional information absent in an electronic chain of custody system.
Screening provides an initial test for drugs of misuse. Although Screening is a cost-efficient method to exclude drug use in most samples, court-admissible results require confirmation of any positive screen. Any samples presumptively positive in Screening will need further confirmation.
In cases where Screening is presumptively positive, additional hair is taken from the original sample to prepare for Extraction. Here, drugs are extracted from hair at a lower concentration compared to other methods (e.g., urine or saliva), making hair drug testing the most challenging method to execute.
Confirmation of any Screening positivity is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive receive a wash before confirmation as required. The entire laboratory sequence from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
