Hair testing is widely recognized as an effective method for identifying drug and alcohol usage. Hair fibers trap biomarkers, offering a comprehensive history of alcohol and drug exposure over time. When collected near the scalp, hair can reveal drug and alcohol use for up to three months. The collection process is straightforward, challenging to tamper with, and convenient to transport.
A 1.5-inch section of roughly 200 hair strands (comparable to the size of a #2 pencil) closest to the scalp provides 100mg of hair, which is ideal for screening and confirmation. For EtG, additional screening, and/or tests exceeding 10 panels, 150mg of the sample is advised. It is recommended to measure the sample with a jeweler’s scale. If scalp hair can't be obtained, an equivalent amount of body hair may be used. When mentioning head hair, we mean scalp hair exclusively. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory process of obtaining a drug test result involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the step where a sample is registered into a laboratory’s system. This step ensures the sample is sealed and transported correctly, assigns a random LAN (Laboratory Accessioning Number), and includes any additional data entry not handled by an electronic chain of custody system.
Screening is a preliminary examination for drugs of abuse. Though Screening is a cost-efficient means to identify drug usage in most samples, a positive result must be confirmed for legal proceedings. Any samples that test presumptively positive in Screening necessitate a follow-up confirmation.
If a sample is found presumptively positive during Screening, additional hair is extracted from the original sample for the Extraction phase. Drugs are then extracted from the hair at a lower concentration than in other methods (e.g., urine or oral fluid), making hair drug screening a more complex process.
Confirmation of a positive screen is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumed positive undergo washing prior to confirmation where necessary. The entire laboratory process from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair designation along with ISO / IEC 17025 accreditation.
