Hair analysis has emerged as a significant method for uncovering substance and alcohol consumption. Hair captures a prolonged record of alcohol and drug use by embedding biomarkers in the strands of developing hair. When hair is clipped close to the scalp, it can offer up to a 90-day detection timeline for alcohol and various drugs. The collection of hair is straightforward, relatively resistant to tampering, and easy to transport.
A sample measuring 1.5 inches with roughly 200 hair strands (around the width of a #2 pencil) taken nearest to the scalp yields 100mg, which is the preferred amount for both preliminary and confirmatory testing. For EtG, additional tests, or tests exceeding 10 panels, 150mg is advisable. It is suggested to measure the sample with a jeweler’s scale. If head hair is not available, an equivalent volume of body hair may be used. Head hair refers specifically to scalp hair. Body hair encompasses all other varieties of hair (facial, axillary, etc.).
Process Overview
There are four primary stages in the lab evaluation of a drug test sample: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the preliminary handling of a sample in a lab’s system. This process entails ensuring that the sample was correctly sealed and transported, assigning it a random LAN (Laboratory Accessioning Number), and carrying out any extra data entry not included by an electronic chain of custody system.
Screening provides an initial rapid assessment for drugs of abuse. Though Screening is an economical means to dismiss drug use in most samples, a positive Screen must be verified to be court-admissible. Samples that are presumptively positive during Screening require further confirmation.
Should a sample show presumptive positivity in Screening, more hair is extracted from the original sample for Extraction. During Extraction, drugs are isolated from hair at concentrations lower than those achievable with other methods (e.g., urine or oral fluid), rendering hair drug testing one of the most challenging methodologies to conduct.
Any positive Screening outcomes are validated through GC/MS, GC/MS/MS, or LC/MS/MS. All suspected positive samples undergo washing before Confirmation if necessary. The complete lab procedure from Accessioning to Confirmation is scrutinized under both the guidelines of the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
