Hair testing is now recognized as an effective means for identifying drug and alcohol consumption. Hair captures a prolonged history of substances by embedding biomarkers within the fibers of the hair as it grows. When obtained near the scalp, hair can reveal a detection period of up to three months for alcohol and drugs. Collecting hair is straightforward, challenging to alter, and facilitates easy transportation.
A sample size of 1.5 inches, consisting of roughly 200 hair strands (comparable to a #2 pencil diameter) nearest to the scalp, yields 100mg of hair, which is ideal for both screening and confirmation. For tests involving EtG, add-ons, or those exceeding 10 panels, a specimen weight of 150mg is suggested. It's advisable to weigh the sample using a jeweler's scale. If scalp hair isn't accessible, a corresponding quantity of body hair may be obtained. When mentioning head hair, it specifically refers to scalp hair. Body hair encompasses all other hair categories (facial, axillary, etc.).
Process Overview
The primary stages in the laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial integration of a sample into a laboratory's system. This process verifies proper sealing and shipping of the sample, assigns a unique LAN (Laboratory Accessioning Number), and completes any necessary data entry that's not captured by an electronic chain of custody system.
Screening performs an initial rapid evaluation for drug substances. While Screening is an economical method to exclude drug usage in most samples, a positive screen must be confirmed for court admissibility. Samples that are preliminarily positive in Screening need secondary confirmation.
Should a sample test positive preliminarily in the Screening phase, additional hair is taken from the original sample and readied for Extraction. This phase extracts drugs from hair at significantly lower concentrations than other methods (such as urine or oral fluid), which is why hair drug screening is the most challenging to execute.
Confirmation for any positive screening outcome is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are washed before confirmation as deemed necessary. The complete laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair accreditation and the ISO / IEC 17025 standards.
