Hair testing is increasingly recognized as a robust method for identifying drug and alcohol consumption. Hair captures a comprehensive profile of alcohol and other drug use by embedding biomarkers within the hair strand as it grows. Collected near the scalp, hair can offer up to a three-month detection period for alcohol and drugs. Collecting hair is straightforward, hard to tamper with, and convenient to transport.
A 1.5-inch portion, about 200 hairs in diameter (roughly the girth of a #2 pencil), taken nearest to the scalp offers 100mg of hair, which is optimal for screening and concluding tests. For EtG, additional tests, and those extending beyond 10 panels, a 150mg sample is advisable. Utilizing a jeweler's scale for weighing the specimen is recommended. If scalp hair is unusable, a comparable quantity of body hair may be used. Head hair denotes scalp hair exclusively, while body hair indicates all other hair types (beard, underarm, etc.).
Process Overview
The drug test result processing in the laboratory is broken into four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the primary intake of a sample into a lab's system. This encompasses ensuring the sample was properly sealed and shipped, generating a unique LAN (Laboratory Accessioning Number), and completing outstanding data entry not included in an electronic chain of custody.
Screening executes a preliminary and swift assessment for substances. While it is a cost-effective means for excluding drug usage in most samples, any positive result in the screening stage requires confirmation for court admissibility. Samples yielding presumptive positives during Screening necessitate additional confirmation.
A presumptive positive from the Screening leads to obtaining more hair from the primary sample for Extraction. In this phase, drug extraction occurs at a lower concentration compared to methods like urine or oral fluids, which makes hair drug screening particularly challenging.
Confirming any positive from screening is performed with GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all samples that are presumptive positives undergo necessary washing. The comprehensive process from Accessioning through Confirmation is conducted under the scrutiny of both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
