Hair assessment is recognized as a robust method for identifying drug and alcohol consumption. Hair archives a long-term record of alcohol and drug use by encasing biomarkers within the fiber of the hair shaft. When cut near the scalp, hair can unveil up to a three-month window for alcohol and drug exposure. Collecting hair is straightforward, relatively hard to tamper with, and convenient to transport.
A sample of 1.5 inches consisting of about 200 hairs (similar in size to a #2 pencil) nearest to the scalp yields 100mg of hair, ideal for screening and validation. For EtG, add-ons, and/or tests exceeding 10 panels, it is suggested to obtain 150mg of hair. Utilizing a jeweler's scale for weighing the sample is advised. If scalp hair cannot be sourced, a similar quantity of body hair can be used. When mentioning head hair, it pertains specifically to scalp hair. Body hair includes all other hair forms (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result is composed of four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial handling of a sample into a lab's system. This step ensures that the sample was correctly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any data entry missed by an electronic chain of custody system.
Screening is a preliminary assessment for drug traces. Though Screening provides a budget-friendly way to exclude drug usage in most samples, a positive screen needs validation for legal admissibility. Any samples identified as presumptively positive in Screening require an additional confirmation step.
Upon obtaining a presumptive positive in the Screening phase, further hair is extracted from the sample for the Extraction phase. In this phase, drugs are isolated from hair at a considerably lower concentration compared to other techniques (like urine or oral fluid), rendering hair drug screening as the most complex procedure.
Validation of any positive screening outcomes is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. All samples identified as presumptive positives are cleansed as necessary prior to confirmation. The complete lab procedure spanning from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 standards.
