Hair analysis has gained recognition as an effective method for identifying drug and alcohol consumption. It offers an extended timeline of substance use by capturing biomarkers within the hair fibers as they grow. When collected near the scalp, hair enables detection of alcohol and other drugs for up to approximately three months. Hair collection is straightforward, rather resistant to tampering, and convenient for transportation.
A 1.5-inch segment containing about 200 hair strands (roughly equivalent to a #2 pencil's thickness) closest to the scalp yields 100mg, which is the optimal amount for screening and validation. For EtG enhancements and/or tests exceeding 10 panels, it's advised to gather 150mg of the sample. Utilizing a jeweler’s scale for weighing the sample is advisable. In cases where scalp hair is inaccessible, a comparable amount of body hair might be used. The term head hair specifically denotes scalp hair only. Body hair encompasses all other hair forms (facial, axillary, etc.).
Process Overview
The key steps involved in processing a drug test result in a lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the foundational step where a sample is introduced into the lab’s system. Tasks include confirming that the sample was correctly sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplementary data input not covered by an electronic chain of custody.
Screening entails a preliminary inspection for drug abuse. Although cost-effective for dismissing drug use in most samples, any positive result in Screening needs to be validated for court admissibility. Samples that yield presumptive positives during Screening must undergo secondary confirmation.
Should a sample show a presumptive positive during Screening, additional hair is extracted from the original sample for the Extraction phase. Here, drugs are isolated from hair at considerably lower concentrations than in other practices (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.
Confirmation of any positive results from the screening is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. Any samples that are presumptive positive undergo washing before confirmation as required. The full lab process, from Accessioning to Confirmation, is examined in accordance with both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
