Hair analysis is now regarded as an effective method for uncovering drug and alcohol consumption. Hair retains a historical record of substances, as biomarkers become embedded within the strands as they grow. A sample cut near the scalp can provide insights into a period covering roughly three months for both alcohol and drugs. Its collection is straightforward, tampering is challenging, and shipping is a breeze.
A proper test sample consists of a 1.5-inch snippet of around 200 strands, approximating the width of a #2 pencil, taken nearest to the scalp, providing 100mg of hair, ideal for both screening and verification. For more comprehensive tests, such as for EtG or those exceeding 10 panels, a sample weighing 150mg is recommended. It's advisable to use a jeweler’s scale for weighing. If scalp hair isn't accessible, an equivalent portion of body hair may be used. "Head hair" strictly refers to scalp hair, while "body hair" encompasses all other types, like facial or underarm hair.
Process Overview
There are four key stages in processing a lab drug test outcome: Accessioning, Screening, Extraction, and Confirmation.
Accessioning starts with integrating a sample into a lab's workflow, ensuring it's securely sealed and sent correctly, linking it to a unique LAN (Laboratory Accessioning Number), and filling in any extra information not captured by the digital custody system.
Screening serves as a preliminary check for substance abuse. It’s a budget-friendly technique for dismissing usage in most samples, but a positive finding here must be confirmed for legal acceptance. Any samples testing positive at this stage will need confirmatory testing.
For specimens anticipating a positive result during Screening, additional hair from the primary sample is required for Extraction. Here, drugs are drawn out from hair at a significantly lower concentration compared to other methods such as urine or saliva tests, hence making hair testing one of the more complex techniques.
Confirmation of positive screenings utilises GC/MS, GC/MS/MS or LC/MS/MS methods. Prior to confirmation, all samples presumed positive undergo washing as necessary. Every step from Accessioning to Confirmation is examined in line with both the CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation.
