The utilization of hair testing has emerged as a significant method for identifying drug and alcohol consumption. Hair captures a prolonged account of alcohol and drug markers by securing them within the strands of hair as they grow. When hair is taken from near the scalp, it can offer a detection timeframe for alcohol and drugs that extends to roughly three months. The collection of hair is straightforward, relatively resistant to tampering, and facilitates convenient shipping.
A 1.5-inch sample consisting of about 200 hairs (roughly equating to the thickness of a #2 pencil) from closest to the scalp delivers 100mg, the optimal amount for screening and validation. For assessments of EtG, supplemental tests, and/or those exceeding 10 panels, a specimen of 150mg is advised. It is suggested to measure the sample using a jeweler’s scale. In scenarios where scalp hair cannot be obtained, a comparable quantity of body hair may be gathered. When mentioning head hair, it specifically means scalp hair. Body hair includes all other types of hair (such as facial, axillary, etc.).
Process Overview
The core steps in processing a drug test in the lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the process of introducing a sample into the lab system initially. This encompasses ensuring that the sample is sealed and dispatched correctly, assigning a LAN (Laboratory Accessioning Number) at random, and completing any additional data entry not covered by an electronic chain of custody system.
Screening is a preliminary rapid check for drug substances. While this is a cost-effective method to eliminate drug presence in most samples, a positive result from Screening needs confirmation in order to be valid in judicial settings. Any samples yielding a positive indication in Screening do mandate a secondary confirmation step.
For samples with a presumptive positive in Screening, additional hair is extracted from the original sample for the Extraction phase. In this phase, the concentration of drugs extracted from hair is considerably lower than that obtained through other methods (such as urine or oral fluid), underscoring the complexity involved in conducting hair drug screening.
Confirmation for any positive Screening outcome is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo necessary washing before confirmation. The entire series from Accessioning to Confirmation is scrutinized following both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
