Hair testing has been recognized as a significant method for identifying drug and alcohol consumption. Hair offers an extensive timeline of substance use by capturing biomarkers within the fibers of the developing hair strand. When obtained near the scalp, hair can offer a detection period of up to roughly 3 months for alcohol and drugs. Hair is straightforward to gather, relatively hard to tamper with, and convenient to send.
A 1.5-inch segment from about 200 strands of hair (approximately the size of a #2 pencil) closest to the scalp will yield 100mg of hair, which is an optimal sample for both screening and confirmation. For EtG, add-ons, or tests beyond 10 panels, it is advisable to collect 150mg of the specimen. We advise using a jeweler’s scale to weigh the specimen. If scalp hair isn’t obtainable, a comparable amount of body hair can be collected. When mentioning head hair, we refer exclusively to scalp hair. Body hair denotes all other hair varieties (such as facial, axillary, etc.).
Process Overview
The primary stages in the lab-handling of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a laboratory’s system. This process involves ensuring the sample was sealed and shipped correctly, assigning a unique LAN (Laboratory Accessioning Number), and performing any supplementary data entry not supplied by an electronic chain of custody framework.
Screening entails a preliminary rapid assessment for drugs of abuse. Although Screening offers a cost-efficient approach to exclude drug usage for most samples, a positive screen requires confirmation to be valid in legal proceedings. Any samples that are presumptive positive in Screening necessitate a secondary confirmation.
If a sample tests presumptively positive during the Screening process, additional hair is drawn from the original specimen and prepped for Extraction. During this phase, drugs are extracted from the hair at a substantially lower concentration compared to other methods (e.g., urine or oral fluids), underscoring why hair drug screening is among the most challenging methodologies.
Any positive screening result is confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation, as needed. The full laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
