Hair tests are now regarded as a robust method for uncovering drug and alcohol consumption. Hair captures long-term use markers by incorporating biomarkers within the hair's growing fiber. When sampled close to the scalp, hair can detect alcohol and drugs for roughly three months. It's simple to gather, somewhat resistant to tampering, and convenient to transport.
A 1.5-inch segment of about 200 hairs (similar in size to a #2 pencil) taken adjacent to the scalp yields 100mg, which is the optimal portion for assessment and verification. For EtG, additional tests, and/or tests exceeding 10 panels, 150mg of the sample is suggested. Utilize a jeweler's scale for specimen measurement. If scalp hair isn't available, an equivalent portion of body hair is an option. Head hair exclusively pertains to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory procedure for drug test processing includes four principal stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning incorporates initial sample processing into a lab's system. This step involves ensuring the sample was sealed and transported properly, assigning a random LAN (Laboratory Accessioning Number), and completing any manual data tasks not covered by an electronic chain of custody system.
Screening provides a preliminary rapid test for drugs of abuse. Although it's a cost-efficient way to dismiss drug use in most samples, any positive screen requires confirmation to be court-admissible. All samples indicating a presumptive positive in Screening mandate a secondary check.
A sample showing presumptive positivity in Screening leads to more hair being taken from the original sample for Extraction. Here, drugs are extracted from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), positioning hair drug screening as the most challenging method to execute.
Confirmation for any positive Screening result is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. Every presumptive positive sample undergoes washing before confirmation if necessary. The complete process from Accessioning to Confirmation is assessed in line with both the CAP (College of American Pathologists) Hair standards and the accreditation to ISO / IEC 17025 standards.
