Recognized as a potent method for identifying substance use, hair testing captures a comprehensive timeline of alcohol and drugs by embedding biomarkers within the evolving hair strand. When obtained close to the scalp, hair allows for a detection span of up to three months for alcohol and drugs. Hair is straightforward to gather, relatively resistant to manipulation, and convenient to transport.
A sample measuring 1.5 inches and comprising about 200 hair strands (roughly the girth of a #2 pencil) near the scalp yields 100mg, which is optimal for both screening and confirmation. For EtG, additional tests, and/or panels exceeding ten, a 150mg specimen is advised. It's best to weigh the sample using a jeweler’s scale. If scalp hair isn’t available, a comparable amount of body hair may be used. When referring to head hair, it specifically means scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result comprises Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into the laboratory system, ensuring proper sealing and shipping, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data entry absent from an electronic chain of custody system.
Screening involves a preliminary overview for drugs of abuse. While it's an economical method to dismiss drug use for most samples, a positive screen requires validation for legal acceptance. Any samples with a presumptive positive in Screening must undergo secondary confirmation.
When a sample shows a presumptive positive during the Screening phase, additional hair from the original specimen is prepared for Extraction. Here, drugs are isolated from hair at much lower concentrations than in other techniques (e.g., urine or oral fluid), illustrating why hair drug testing is particularly challenging to execute.
Confirmation of any positive Screening result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are washed before confirmation, as necessary. From Accessioning through to Confirmation, the entire laboratory workflow is assessed under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
