Hair analysis has become known as a potent means for identifying drug and alcohol consumption. Hair offers a prolonged record of alcohol and drug presence by capturing biomarkers within the strands of the growing hair. When collected close to the scalp, hair can provide an estimated 3-month detection window for substances. Hair collection is straightforward, somewhat resistant to tampering, and convenient to transport.
A 1.5-inch snippet consisting of around 200 strands of hair (about the size of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal sample size for screening and confirmation. For EtG add-ons and/or tests exceeding 10 panels, 150mg of the sample is advised. It is recommended to weigh the specimen using a jeweler’s scale. If scalp hair is unobtainable, a comparable amount of body hair may be used. When mentioning head hair, it refers strictly to scalp hair. Body hair denotes all other hair types (facial, axillary, etc.).
Process Overview
The principal stages in the laboratory analysis of a drug test include Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial processing of a sample within a laboratory's system. This step involves checking that the sample was correctly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not supplied by an electronic chain of custody system.
Screening is a preliminary rapid assessment for drugs of abuse. While Screening is a cost-effective approach to determine the absence of drug usage in most samples, a positive result requires confirmation to be court-admissible. Samples that appear positive in Screening must undergo secondary confirmation.
In cases of presumptive positives in the Screening phase, further hair is extracted from the initial sample and prepared for Extraction. This stage involves extracting drugs from hair at significantly lower concentrations than in other methodologies (e.g., urine or oral fluid), which is why hair drug testing is the most challenging methodology to administer.
Confirmation of any positive results from Screening is carried out by GC/MS, GC/MS/MS or LC/MS/MS. All samples presumed positive undergo washing before confirmation, if necessary. The complete laboratory process, from Accessioning to Confirmation, is assessed under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
