Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair captures a long-term record of drug and alcohol use by embedding biomarkers within the strands as they grow. When collected close to the scalp, hair can offer a detection window of up to three months for drugs and alcohol. The collection process is straightforward, making it hard to tamper with, and easy to transport.
A 1.5-inch sample containing roughly 200 strands of hair (comparable to a #2 pencil size) nearest to the scalp will yield 100mg of hair, which is the optimal sample size for screening and confirmation. For EtG, add-ons, and tests exceeding 10 panels, 150mg of the sample is preferable. We advise weighing the sample using a jeweler’s scale. In the case that scalp hair is missing, an equivalent amount of body hair can be gathered. Head hair explicitly refers to scalp hair, while body hair pertains to other types (such as facial or axillary hair).
Process Overview
There are four fundamental stages in the laboratory processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary processing of a sample into a laboratory’s database. This process includes confirming the sample's proper sealing and shipping, assigning a unique LAN (Laboratory Accessioning Number), and entering any supplementary data not recorded by an electronic chain of custody system.
Screening is a preliminary check for drugs of abuse. Although Screening is a cost-efficient method to rule out drug use in most samples, a positive screen must be confirmed to be legally admissible in court. Any samples that are preliminary positive in Screening necessitate a secondary confirmation.
If a sample is preliminarily positive at the Screening phase, additional hair is extracted from the initial sample and prepared for Extraction. During this stage, the drugs are retrieved from hair at a significantly lower concentration than with other methods (e.g., urine or oral fluid), making hair drug screening one of the most challenging methodologies to execute.
All positive screening results are verified using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples are cleaned prior to confirmation if necessary. The entire laboratory procedure from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
