Hair examinations have emerged as an effective means for identifying drug and alcohol consumption. Hair retains a long-standing record of alcohol and drug use by embedding biomarkers within the fibers of the developing hair strand. When gathered near the scalp, hair samples can offer up to roughly a 3-month detection range for alcohol and other substances. Hair is easy to gather, challenging to tamper with, and straightforward to transport.
A sample of 1.5 inches containing roughly 200 hair strands (comparable in size to a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal amount for analysis and verification. For EtG extensions, and/or tests exceeding 10 panels, a 150mg sample is advised. Using a jeweler’s scale to weigh the sample is recommended. If scalp hair is missing, a comparable quantity of body hair may be collected. When mentioning head hair, we specifically mean scalp hair. Body hair includes all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test consists of four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial incorporation of a sample into the lab’s system. This involves confirming the sample's proper sealing and shipment, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any ancillary data input not provided by an electronic chain of custody mechanism.
Screening carries out a swift preliminary check for drugs of misuse. While Screening is a budget-friendly method to dismiss drug use in most samples, a positive result requires validation to be permissible in legal settings. Samples showing preliminary positive results in Screening must undergo further confirmation.
Should a sample show preliminary positive results during Screening, additional hair is extracted from the initial sample and prepped for Extraction. In this phase, drugs are retrieved from hair at significantly lower concentrations than other techniques (e.g., urine or oral fluid), which is why hair drug examinations are the most challenging technique to execute.
Confirmation for any positive results from screening is conducted using GC/MS, GC/MS/MS or LC/MS/MS. All samples with preliminary positive results are laundered prior to confirmation if necessary. The complete lab process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the certification to ISO / IEC 17025 standards.
