Hair analysis is increasingly regarded as a significant method for identifying drug and alcohol consumption. Hair serves as a historical record by capturing biomarkers within the strands of growing hair. When taken near the scalp, hair can reveal usage of alcohol and drugs for a period of up to roughly 90 days. Collecting hair is straightforward, relatively tamper-resistant, and convenient to transport.
A 1.5-inch section containing about 200 hair strands (approximately the thickness of a #2 pencil) from close to the scalp yields 100mg of hair, the perfect amount for both screening and confirmation. For tests including EtG, add-ons, or panels exceeding 10, a 150mg sample is preferable. It is advisable to weigh the sample using a jeweler's scale. If no scalp hair is accessible, a similar quantity of body hair can be obtained. The term 'head hair' strictly refers to scalp hair, while 'body hair' includes all other types (facial, axillary, etc.).
Process Overview
The primary phases in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning constitutes the initial sample integration into a lab system. This step involves ensuring the sample is sealed and transported correctly, creating a random LAN (Laboratory Accessioning Number), and completing any additional data entry not handled by an electronic chain of custody system.
Screening involves a preliminary examination for illegal drugs. While Screening is an efficient way to dismiss drug use in most cases, any positive result must be verified to be legally valid. Samples with a presumed positive result during Screening need a further confirmation process.
For any presumed positive sample in the Screening phase, extra hair is extracted from the original sample for further Extraction. In this phase, drug compounds are isolated from hair at much lower concentrations than other methods (e.g., urine or oral fluid), making hair drug analysis one of the most challenging techniques to execute.
Verification of any positive screening outcomes is accomplished via GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing presumptive positives are cleansed before confirmation as necessary. The whole laboratory method from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.
