Hair testing is considered an effective method for identifying drug and alcohol use. It captures a lengthy history of substance use, storing biomarkers within the fibers of the developing hair strand. When taken nearest to the scalp, hair can reveal drug and alcohol usage over a period of roughly three months. Hair collection is straightforward, fairly resistant to tampering, and easy to send.
A sample measuring 1.5 inches from about 200 hair strands (approximately the size of a #2 pencil) nearest to the scalp provides 100mg of hair, which is optimal for screening and confirmation. To test for EtG, additional substances, and/or to exceed 10 panels, 150mg of the sample is advised. Using a jeweler’s scale to weigh the specimen is suggested. If scalp hair can't be obtained, an equivalent quantity of body hair can be used. Head hair specifically refers to scalp hair, while body hair encompasses all other types (e.g., facial, axillary).
Process Overview
The core stages in processing a drug test result in the lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial processing of a sample into a lab’s system, including verifying the sample’s integrity upon receipt, assigning a random LAN (Laboratory Accessioning Number), and inputting any additional data absent from an electronic chain of custody system.
Screening is a preliminary check for substances of abuse. It efficiently rules out drug usage in most samples, but a positive screen must be confirmed to be legally viable. Samples that are presumptively positive in Screening require further confirmation.
In cases where a sample is presumptively positive at the Screening phase, additional hair is taken from the original specimen and readied for Extraction. During this phase, drugs are retrieved from hair at significantly lower concentrations than with other methods (like urine or oral fluid), making hair drug screening particularly challenging.
Confirmation of preliminary positive results is done via GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive undergo cleaning before confirmation as required. The entire lab process from Accessioning to Confirmation is evaluated under both CAP (College of American Pathologists) Hair criteria and accreditation adhering to ISO / IEC 17025 standards.
