Hair examinations are increasingly recognized as an effective instrument in identifying drug and alcohol consumption. Hair archives a prolonged record of substance use by embedding biomarkers in the structure of the developing hair shaft. When obtained near the scalp, hair can demonstrate a detectability window for substances up to about 90 days. Hair samples are straightforward to gather, somewhat challenging to tamper with, and convenient to transport.
A 1.5-inch segment comprising roughly 200 hair strands (comparable in size to a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal quantity for both screening and validation. For EtG, additional screening, and/or more than 10-panel tests, a 150mg sample is suggested. It is advisable to quantify the sample using a jeweler’s scale. In the absence of scalp hair, an equivalent volume of body hair is acceptable. When mentioning head hair, we exclusively mean scalp hair. Body hair pertains to all other types of hair (facial, axillary, etc.).
Process Overview
Lab processing of a drug test involves four essential stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning features the preliminary handling of a specimen into a lab’s database. It encompasses checking the proper sealing and shipping of the sample, allocating a random LAN (Laboratory Accessioning Number), and finishing any extra data input absent in an electronic chain of custody mechanism.
Screening executes a preliminary rapid scan for substance misuse. While Screening is a budget-friendly approach to dismiss potential drug use in most samples, a positive screening result requires confirmation for legal acceptability. Any samples with presumptive positives during Screening necessitate subsequent verification.
In instances of a presumptive positive result during Screening, additional hair is extracted from the original sample and processed for Extraction. Here, substances are isolated from hair at relatively lower concentrations than other methods (e.g., urine or oral fluids), distinguishing hair drug screening as the most intricate method to conduct.
Confirmation of any positive screening outcome is conducted using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All tentative positive samples undergo cleansing before confirmation as essential. From Accessioning to Confirmation, the whole laboratory procedure is critically examined under both the CAP (College of American Pathologists) Hair certification and ISO / IEC 17025 standards adherence.
