In recent years, hair analysis has become an effective method for identifying the usage of drugs and alcohol. Hair strands capture and preserve biomarkers as they grow, offering an extended timeline of substance intake. When obtained near the scalp, hair can indicate drug or alcohol consumption for up to roughly 90 days. Collecting hair is straightforward, hard to tamper with, and convenient for transportation.
A 1.5-inch section containing approximately 200 hair strands (similar in size to a #2 pencil) near the scalp yields 100mg of hair, which is optimal for both screening and confirmation procedures. For tests focusing on EtG, add-ons, or those exceeding 10 panels, 150mg is advised. It is best to weigh the hair using a jeweler’s scale. Should scalp hair be unavailable, an equivalent portion of body hair can be gathered. When mentioning head hair, we specifically refer to scalp hair. Body hair encompasses all other types, including facial and axillary hair.
Process Overview
The laboratory evaluation of a drug test result involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage where a sample is logged into a laboratory's tracking system. This step includes confirming that the sample was securely sealed and properly shipped, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any data entry missing from an electronic custody chain.
Screening is a preliminary assessment to detect potential drug abuse. Although screening offers a cost-efficient method to discount drug use in most specimens, any positive screen must be verified to be valid in legal contexts. Samples that yield a presumptive positive result during screening require further confirmation.
In cases where a sample tests presumptively positive at the Screening stage, additional hair from the original sample is used for Extraction. During Extraction, drugs are isolated from hair at much lower concentrations compared to other testing techniques (like urine or oral fluid), making hair drug evaluation notably challenging to execute.
Confirmation of any screening positives is carried out using GC/MS, GC/MS/MS, or LC/MS/MS procedures. Before Confirmation, all presumptive positive samples are cleansed as necessitated. The comprehensive lab process, from Accessioning to Confirmation, is rigorously reviewed following both the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
