Seen as a strong method, hair testing assists in uncovering drug and alcohol consumption. Hair captures a prolonged archive of substances through trapping biomarkers within the strands' fibers as they grow. When gathered near the scalp, hair can indicate substance use over approximately a three-month timeframe. The collection process is straightforward, tampering is challenging, and it is also easy to mail.
A sample measuring 1.5 inches consisting of about 200 hair strands (similar to the girth of a #2 pencil) near the scalp provides 100mg of hair, ideal for both screening and confirmation. For tests involving EtG, additional tests, or those surpassing 10 panels, a 150mg sample is preferred. It is advisable to use a jeweler’s scale for specimen measurement. Should scalp hair be absent, a similar volume of body hair is an alternative. By head hair, we exclusively mean scalp hair, while body hair encompasses all other sorts (facial, axillary, etc.).
Process Overview
The lab analysis of a drug test result is segmented into four major stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning denotes the initial integration of a sample into the laboratory’s system. This includes confirming the sample's proper seal and shipment, assigning it a random LAN (Laboratory Accessioning Number), and fulfilling any additional data entry not facilitated by an electronic chain of custody system.
Screening is a preliminary, rapid test for drugs of abuse. Although economical for excluding drug use in most samples, a positive screening necessitates confirmation for court validity. Samples that test presumptively positive in Screening must undergo secondary confirmation.
Should a sample reflect a presumptive positive during Screening, extra hair is extracted from the primary specimen for the Extraction stage. Here, drugs are extracted from hair at a considerably lower concentration than in methodologies like urine or oral fluid, making hair drug screening notably complex.
Confirmation of any positive screening result is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed as necessary before confirmation. The entire lab process—from Accessioning to Confirmation—is examined under both the CAP (College of American Pathologists) Hair designation and backing by ISO / IEC 17025 standards.
