The use of hair testing has emerged as an effective means for identifying drug and alcohol consumption. Hair captures a historical record of alcohol and drugs over time by embedding biomarkers within the fibers of the developing hair strand. When collected near the scalp, hair offers a detection span of up to roughly three months for both alcohol and drugs. Hair collection is straightforward, is relatively resistant to tampering, and can be easily sent.
A sample measuring 1.5 inches with around 200 strands of hair (roughly the diameter of a #2 pencil) closest to the scalp yields 100mg of hair, which is the preferred sample size for both screening and confirmation purposes. For tests like EtG, add-ons, and ones that exceed ten panels, 150mg of the specimen is advisable. It's suggested to use a jeweler’s scale to measure the specimen. If scalp hair can't be provided, an equivalent volume of body hair can be gathered. In this context, head hair exclusively denotes scalp hair, while body hair encompasses all other types (such as facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
At the Accessioning stage, a sample is initially processed into a lab's system. This phase involves ensuring the sample was sealed and sent correctly, assigning it a random LAN (Laboratory Accessioning Number), and completing any additional data entry needed that wasn't supplied by an electronic chain of custody system.
Screening serves as an initial, rapid check for substances of abuse. While Screening is a cost-efficient method to exclude drug usage for most samples, a positive screen requires confirmation to be valid in legal settings. Any samples presumed positive during Screening mandate further confirmation.
Should the initial Screening phase suggest a positive result, additional hair is taken from the original sample to prepare for Extraction. Drugs are extracted from hair at much lower concentrations compared to other techniques (such as urine or oral fluid), making hair drug screening among the most challenging methods to execute.
Confirmation of any positive screening outcome is accomplished through GC/MS, GC/MS/MS, or LC/MS/MS. All presumed positive samples undergo washing before confirmation as necessary. The complete lab process, spanning from Accessioning to Confirmation, undergoes review under both the CAP (College of American Pathologists) Hair designation and the accreditation meeting ISO / IEC 17025 standards.
