Hair testing is now recognized as an effective method for detecting drugs and alcohol. By embedding biomarkers within the growing strands, hair provides a comprehensive history of substance use. When gathered near the scalp, it offers about a 3-month timeframe for identifying alcohol and other substances. Hair collection is straightforward, hard to tamper with, and convenient for sending.
A sample measuring 1.5 inches with approximately 200 hair strands (roughly the thickness of a #2 pencil) from the scalp will supply 100mg of hair, which is ideal for screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, 150mg is advisable. Utilizing a jeweler’s scale for weighing is suggested. Should scalp hair be lacking, a similar quantity of body hair can be used instead. When mentioning head hair, we specifically mean scalp hair. Conversely, body hair includes various kinds of hair (facial, axillary, etc.).
Process Overview
There are four primary stages in the laboratory handling of drug test samples: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial step where a sample is registered into the lab's system. This step ensures the sample's proper sealing and shipment, allocates it a unique LAN (Laboratory Accessioning Number), and completes any missing information not captured by electronic chain of custody systems.
Screening is the preliminary assessment to detect substances of abuse. Although Screening is cost-effective for deducing drug absence in most samples, any positive findings require confirmation for legal validity. Samples appearing positive during Screening undergo further verification.
In cases where Screening suggests a positive result, additional hair from the sample is used for the Extraction stage. In this phase, substances are isolated from hair at concentrations much lower than those in other methods (e.g., urine or oral fluid), making hair drug screening one of the most challenging procedures.
Confirming any positive Screening is conducted via GC/MS, GC/MS/MS, or LC/MS/MS. All potential positive samples are cleansed before confirmation if necessary. The complete lab process from Accessioning to Confirmation adheres to standards set by the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
