Hair analysis is widely regarded as an effective means for identifying drug and alcohol consumption. The structure of hair retains traces of alcohol and drugs, acting as a historical record that lasts beyond several months. When hair is sampled near the scalp, it offers a detection span of roughly three months for alcohol and drugs. The collection of hair is straightforward, and it possesses a lower likelihood of tampering or adulteration compared to other methods, and it is convenient to handle during transportation.
Obtaining a 1.5-inch segment of approximately 200 hair strands (equivalent to the size of a #2 pencil) from the area nearest to the scalp yields approximately 100mg of hair, which is ideal for initial assessments and validations. For EtG testing, add-ons, and/or panels exceeding 10, a larger sample of 150mg is preferable. Use a jeweler’s scale for precise measurement. In cases where scalp hair isn't available, a similar quantity of body hair can be used. References to head hair pertain solely to the hair on the scalp. Body hair encompasses other types, such as facial and axillary hair.
Process Overview
There are four principal stages in the lab processing of a drug test: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary handling of a sample within a laboratory system. It involves assuring the sample's secure seal during transportation, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data input absent from an electronic chain of custody system.
Screening performs an initial rapid assessment for substances of abuse. Although it provides an economical method to exclude drug consumption in most samples, any positive screens require confirmation to be legally defensible. Samples indicating presumptive positivity during Screening necessitate further validation.
Should a sample show presumptive positivity at the Screening phase, additional hair is obtained from the original sample for Extraction. This phase involves isolating drugs from hair at concentrations markedly lower than other methods (e.g., urine or oral fluid), rendering hair drug testing particularly intricate.
To verify any positive Screening outcomes, techniques such as GC/MS, GC/MS/MS, or LC/MS/MS are utilized. Prior to validation, all samples with presumptive positivity are cleaned as necessary. From Accessioning to Confirmation, the whole lab procedure is scrutinized under both the CAP (College of American Pathologists) designation for hair and ISO / IEC 17025 accreditation standards.
