Hair assessment is now recognized as an effective mechanism for identifying drug and alcohol consumption. Hair strands capture and store biomarkers of drugs and alcohol in their growing fibers, offering a comprehensive timeline of use. When hair samples are collected near the scalp, they can indicate drug or alcohol intake over a period of up to three months. The sampling process is straightforward, hard to tamper with, and convenient to transport.
A sample measuring 1.5 inches, consisting of roughly 200 hair strands (comparable to the diameter of a #2 pencil) near the scalp, yields 100mg of hair, which is optimal for both screening and verification. For EtG enhancements and/or evaluations exceeding 10 panels, 150mg of the sample is advisable. It is suggested to use a jeweler’s scale for weighing the sample. Should scalp hair be unavailable, a comparable quantity of body hair is permissible. When we mention head hair, it exclusively refers to scalp hair. Body hair encompasses other bodily hair (facial, axillary, etc.).
Process Overview
The laboratory processing of drug test results involves four crucial stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial integration of a sample into the lab’s system, which includes confirming that the sample was appropriately sealed and delivered, allocating a unique LAN (Laboratory Accessioning Number), and finishing any supplementary data entry absent from electronic chain of custody formats.
Screening serves as a preliminary rapid test for abuse substances. Despite being a cost-effective measure for negating drug presence in most samples, any positive results in Screening necessitate confirmation to stand in judicial settings. Samples with presumptive positives in Screening are required to undergo secondary confirmation.
In instances where samples show a presumptive positive during Screening, further hair extraction from the initial sample is undertaken for the Extraction phase. In this procedure, substances are extracted from hair at a much lower concentration than conventional methods (such as urine or oral swabs), thus making hair drug testing the most challenging procedure to conduct.
Confirmation for any positive results in screening is done through GC/MS, GC/MS/MS or LC/MS/MS. All samples that are presumptively positive undergo washing before confirmation as necessary. The entire lab process, from Accessioning through Confirmation, is conducted following CAP (College of American Pathologists) regulations and ISO / IEC 17025 accreditation standards.
