The utilization of hair testing has emerged as a robust method for identifying drug and alcohol consumption. Hair can reveal a substantial history of alcohol and drug use by encapsulating biomarkers within the strands as they grow. When the hair sample is taken near the scalp, it can provide an approximate 90-day window to detect the presence of alcohol and drugs. Collecting hair is straightforward, challenging to tamper with, and convenient to transport.
A sample measuring 1.5 inches and containing around 200 hair strands (approximately the thickness of a #2 pencil) nearest to the scalp equates to 100mg, providing the optimal quantity for both screening and validation. For EtG, add-ons, and/or evaluations beyond 10 panels, it is suggested to use 150mg of the sample. Use a jeweler’s scale for accurate specimen weight. If scalp hair isn't available, an equivalent amount of body hair can be gathered. When discussing head hair, we mean scalp hair only. Body hair encompasses other types of hair (facial, axillary, etc.).
Process Overview
The four primary components in processing a drug test result in a lab are Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the initial processing of a sample is integrated into a laboratory’s system. This step involves confirming the sample’s proper sealing and shipment, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any missing data entry not included in an electronic chain of custody system.
Screening acts as a preliminary rapid test for detecting drugs of abuse. Despite being a cost-efficient method to rule out drug presence for most samples, a screen that returns positive must be verified to hold up in legal proceedings. All samples that are presumptively positive during Screening require a second confirmation step.
In cases where a sample is presumptively positive during Screening, additional hair is extracted from the initial sample and readied for Extraction. In this phase, drugs are isolated from hair at a concentration much finer than other methods (e.g., urine or oral fluid), which makes hair drug screening the most challenging technique to execute.
Confirmation for any positive screening outcome occurs through GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptive positives undergo necessary washing before confirmation. The entire lab process, from Accessioning to Confirmation, is verified under CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: While commonly called "hair follicle tests", the analysis is performed on the hair strand, not on the follicle beneath the scalp.
