The assessment of hair has gained recognition as an effective method for identifying drug and alcohol consumption. Hair retains a historical record of substances by securing biomarkers within the constructing hair shaft. When clipped near the scalp, it can reveal substance usage for a timeframe of up to three months. Hair is straightforward to gather, challenging to tamper with, and convenient to transport.
A sample measuring 1.5 inches of approximately 200 hair strands (about the width of a #2 pencil) closest to the scalp provides a 100mg sample, ideal for both screening and verification. For EtG analyses, extra assessments, and/or tests surpassing 10 panels, a 150mg sample is suggested. Utilizing a jeweler's scale is recommended for precise measurement. In the absence of scalp hair, a similar quantity of body hair may be used. When we mention head hair, we specifically refer to scalp hair. Other types of hair (facial, axillary, etc.) are categorized as body hair.
Process Overview
There are four primary stages in the laboratory evaluation of a drug test, which include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial entry of a sample into a laboratory's records. This procedure confirms the sample was securely sealed and transported, allocates a random LAN (Laboratory Accessioning Number), and fulfills any outstanding data entry absent in an electronic chain of custody protocol.
Screening consists of a preliminary, rapid assessment for the presence of drugs. Although Screening economically determines drug usage for most samples, any positive result must undergo confirmation to be valid in legal settings. Presumptive positive results in Screening necessitate further corroboration.
If a sample receives a presumptive positive in Screening, additional hair is extracted from the original sample and readied for Extraction. This phase involves isolating drugs from hair, which occurs at much lower concentrations compared to other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.
Confirmation of any positive screen is accomplished through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples undergo cleansing before confirmation as necessary. The entire examination process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair directive and the compliance with ISO / IEC 17025 criteria.
