Hair testing has gained recognition as an effective mechanism for identifying drug and alcohol consumption. Hair captures a comprehensive timeline of alcohol and drug usage by embedding biomarkers within the strands as it grows. By gathering hair near the scalp, one can achieve an estimated 3-month detection period for alcohol and drugs. Hair is easy to obtain, relatively resistant to tampering, and conveniently transportable.
A 1.5-inch section consisting of roughly 200 hair strands (about the thickness of a #2 pencil) nearest to the scalp is ideal for providing 100mg of hair, which is the preferred sample quantity for both screening and confirmation. For EtG, supplemental tests, and tests exceeding 10 panels, a specimen of 150mg is advisable. We suggest the specimen be measured on a jeweler’s scale. Should scalp hair be inaccessible, an equivalent quantity of body hair can be used. When mentioning head hair, it specifically refers to scalp hair only. Body hair encompasses other hair types (e.g., facial, axillary).
Process Overview
The pivotal steps in the laboratory's handling of a drug test result consist of Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial integration of a sample into a laboratory's workflow, which includes ensuring the sample was properly sealed and transported, generating a random LAN (Laboratory Accessioning Number), and fulfilling any additional data input absent from an electronic chain of custody system.
Screening entails an initial rapid assessment for drugs of abuse. While Screening is a cost-efficient method to eliminate drug presence in most samples, a positive screen must undergo confirmation to be valid in legal contexts. Samples that test presumptively positive in Screening require further confirmation.
Should a sample indicate a presumptive positive in the Screening phase, additional hair is removed from the original specimen and made ready for Extraction. This phase involves extracting drugs from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), rendering hair drug testing a challenging methodology to execute.
Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples are cleansed before confirmation as necessary. The complete laboratory protocol from Accessioning to Confirmation undergoes evaluation according to both the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.
