Hair testing is regarded as an efficient method for identifying drug and alcohol consumption. It records a historical account of alcohol and drugs by locking biomarkers within the hairs as they form. When taken near the scalp, hair can offer a detection range of up to 3 months for alcohol and drugs. Hair is straightforward to collect, challenging to tamper with, and easy to transport.
A 1.5-inch portion of around 200 hair strands (roughly equivalent to a #2 pencil thickness) near the scalp yields 100mg of hair, the optimal sample size for testing and confirmation. For EtG, supplements, and/or tests exceeding 10 panels, a recommendation of 150mg of the sample is provided. It's advised to weigh the sample on a precision scale. If scalp hair isn't available, an equal quantity of body hair may be taken. By head hair, we mean scalp hair exclusively. Body hair covers all other forms (facial, axillary, etc.).
Process Overview
The process of analyzing a drug test result involves four main steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial handling of a sample in a lab’s database. It involves checking that the sample was appropriately sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and entering any additional data absent in an electronic chain of custody system.
Screening performs an initial check for substances of abuse. While Screening is cost-efficient for negating drug use in most samples, a positive finding requires confirmation to be valid in legal settings. Any samples that show presumptive positives in Screening necessitate further confirmation.
In case a sample shows a presumptive positive in Screening, more hair is extracted from the primary sample and readied for Extraction. During Extraction, drugs are pulled from the hair at significantly lower concentrations than other types (e.g., urine or oral fluid), making hair drug screening notably challenging.
Positive screening results undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation if required. The comprehensive lab process from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair protocols and accreditation by ISO / IEC 17025 standards.
