Hair screening is recognized as an effective method for identifying drug and alcohol consumption. The hair captures a prolonged history of substances by embedding biomarkers within its fibers. When clipped near the scalp, it can reveal up to nearly a 3-month detection timeline for substances like alcohol and drugs. Collection of hair is uncomplicated, somewhat resistant to tampering, and straightforward to transport.
A 1.5-inch segment of roughly 200 hair strands (comparable to the size of a #2 pencil) nearest the scalp yields 100mg of hair, which is the optimal amount for both screening and verification. For EtG tests, supplementary analyses, and/or tests that exceed 10 panels, a specimen of 150mg is advisable. We suggest using a jeweler’s scale for weighing the sample. If the head hair is not accessible, a comparable quantity of body hair may be acquired. By head hair, we mean scalp hair exclusively. Body hair denotes all other hair types (facial, axillary, etc.).
Process Overview
The four principal steps in processing a drug test result in the lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary integration of a sample into the laboratory system. This process includes ensuring that the sample was appropriately sealed and transported, assigning it a random LAN (Laboratory Accessioning Number), and addressing any further data entry that an electronic chain of custody system does not provide.
Screening involves an initial prompt assessment for substance abuse. Although Screening is an economical method to dismiss drug usage for most samples, a positive result must be confirmed to be eligible for legal proceedings. Any samples that exhibit preliminary positive results in Screening require secondary confirmation.
If a sample shows a preliminary positive in the Screening stage, additional hair is extracted from the initial sample and readied for Extraction. During this phase, drugs are removed from hair at a considerably diminished concentration than in alternative techniques (ex. urine or oral fluid), which makes hair drug screening a challenging method to execute.
Confirmation of any positive screening outcome is executed via GC/MS, GC/MS/MS or LC/MS/MS. All samples reflecting presumptive positives undergo washing prior to confirmation as deemed necessary. The entire lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and is accredited to ISO / IEC 17025 standards.
