Hair analysis has gained recognition as an effective method for identifying drug and alcohol consumption. Hair records a prolonged history of substances by embedding markers in the growing strands. When collected near the scalp, hair can offer up to a 3-month period for detecting alcohol and drugs. Hair is straightforward to gather, relatively tricky to tamper with, and convenient to transport.
A 1.5-inch section consisting of around 200 hair strands (comparable to a #2 pencil's width) closest to the scalp generates 100mg of hair, the optimal sample for evaluation and verification. For EtG, additional testing, and/or tests above 10 panels, a 150mg sample is advised. It's suggested to weigh specimens using a jeweler’s scale. If head hair isn't available, a corresponding quantity of body hair can be gathered. By head hair, we imply scalp hair specifically. Body hair encompasses all other types (such as facial, axillary, etc.).
Process Overview
The four central steps in the lab analysis of a drug test are Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers the preliminary processing of a sample within a lab's system. This comprises confirming the sample’s proper sealing and shipment, allocating a random LAN (Laboratory Accessioning Number), and completing any extra data entry not supplied by an electronic chain of custody system.
Screening features an initial brief evaluation for drug misuse. Though Screening is an economical approach to dismiss drug use in most samples, a positive screen must be verified to be court-admissible. Any samples suspected positive during Screening necessitate further Confirmation.
If a sample is suspected positive during the Screening phase, more hair is extracted from the initial sample and is prepped for Extraction. In this phase, drugs are separated from hair at substantially lower concentrations than alternative methods (such as urine or oral fluid), making hair drug testing the most intricate method to execute.
Confirmation of any Screening positive result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples positive for presumptive results are cleaned before confirmation as required. The full lab process from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.
