The utilization of hair testing is now acknowledged as an effective method for identifying drug and alcohol consumption. Hair captures biomarkers within the strands, offering a prolonged record of substance use. When sampled near the scalp, hair can reveal usage of drugs and alcohol for up to a 3-month period. The collection process is straightforward, relatively resistant to tampering, and convenient for transportation.
Gathering a 1.5-inch segment consisting of roughly 200 strands of hair (about the width of a #2 pencil) closest to the scalp will yield 100mg of hair, which is the optimal amount for evaluation and verification. For EtG, add-ons, or screenings over 10 panels, a 150mg sample is advised. It is suggested to weigh the hair sample using a jeweler’s scale. In the absence of scalp hair, a comparable quantity of body hair may be used. The term head hair specifically refers to scalp hair, whereas body hair includes all other hair (facial, axillary, etc.).
Process Overview
The procedure for processing a drug test result in the lab encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial processing stage, where a sample gets integrated into the lab’s system. Steps include confirming proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing data entry beyond what an electronic chain of custody system provides.
Screening offers an initial evaluation for the presence of drugs. While it serves as a cost-effective method to exclude drug usage in most samples, any positive screen must be affirmed for legal admissibility. Samples showing presumptively positive results in Screening require a subsequent confirmation.
Should a sample test as presumptively positive during Screening, additional hair is taken from the original sample for Extraction. In this phase, drugs are extracted from hair at a far lower concentration than other methods (e.g., urine or oral fluids), demonstrating why hair drug testing represents a particularly challenging methodology.
GC/MS, GC/MS/MS, or LC/MS/MS techniques are used to confirm any positive results detected during the screening. Before confirmation, all presumptive positive samples undergo washing as necessary. The entire lab process, from Accessioning to Confirmation, is scrutinized under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.
