Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. The strands of hair serve as a record of alcohol and narcotics usage by encapsulating biomarkers within the hair's fibers. Hair samples taken near the scalp can offer detection capabilities for up to roughly three months for both alcohol and drugs. Hair is easy to collect, relatively challenging to tamper with, and straightforward to transport.
A sample of 1.5 inches, comprising about 200 hair strands (comparable to the thickness of a #2 pencil) near the scalp, will yield 100mg of hair, which is the optimal sample for both screening and confirmation. For EtG, additional factors, and/or tests exceeding 10 panels, a sample size of 150mg is advised. It's suggested to measure the hair sample using a jeweler's scale. In situations where scalp hair is not available, an equivalent quantity of body hair can be collected. By head hair, we specifically mean scalp hair. Body hair includes all other hair types, such as facial and axillary hair.
Process Overview
The laboratory process for drug testing consists of four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the beginning of incorporating a sample into the lab's system. This step includes confirming the sample's seal and proper shipment, generating a random Laboratory Accessioning Number (LAN), and finalizing any data entry not covered by an electronic chain of custody system.
Screening involves a preliminary rapid test for drug usage. Although Screening is a cost-efficient method to eliminate drug use detection in most samples, a positive result necessitates confirmation for court admissibility. Any samples that are presumed positive during Screening require further confirmation.
Suppose a sample is presumed positive in the Screening phase, additional hair from the original sample is used for Extraction. In this step, drugs are removed from hair at a significantly lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug testing the most complex method to execute.
Confirming any positive results from screening is done using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are washed prior to confirmation as required. The comprehensive laboratory procedure, from Accessioning to Confirmation, is assessed under the CAP (College of American Pathologists) Hair standards and the accreditation to ISO/IEC 17025 standards.
