Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. By embedding biomarkers within the growing strands, hair offers a comprehensive historical account of substance intake. Samples taken near the scalp can provide detection for up to approximately three months. Hair collection is straightforward, challenging to tamper with, and simple to transport.
A 1.5-inch segment comprising around 200 hair strands, comparable to the thickness of a #2 pencil, yields 100mg, ideal for screening and confirmation procedures. For EtG, additional tests, or panels above ten, 150mg is advised. We suggest using a jeweler’s scale for precise specimen weighing. Should scalp hair be inaccessible, a similar quantity of body hair can be taken. "Head hair" refers exclusively to scalp hair, while "body hair" includes all other categories (e.g., facial, axillary).
Process Overview
The drug testing laboratory workflow encompasses four principal stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is initially integrated into the laboratory's system. This phase includes verifying the sample's seal and shipment conditions, generating a random LAN (Laboratory Accessioning Number), and finalizing any data entry lacking in an electronic chain of custody system.
Screening is a preliminary and efficient check for substance abuse. While it effectively rules out drug usage for most cases, a positive screen requires verification for court admissibility. Presumptive positive samples in the Screening stage necessitate secondary confirmation.
Should a sample result as presumptively positive in Screening, additional hair from the specimen is allocated for Extraction. Here, drug compounds are isolated from hair at notably lower concentrations than with methods like urine or oral fluids, establishing hair testing as the most challenging methodology.
Confirmation for any positive screening outcome utilizes GC/MS, GC/MS/MS, or LC/MS/MS. Samples presumptively positive are washed ahead of confirmation when appropriate. Every stage from Accessioning to Confirmation adheres to CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
Advantages of hair drug testing:
Limitations:
Note: Often termed "hair follicle tests", the analysis is conducted on the hair strand, not the subdermal hair follicle.
