Using hair for testing is recognized as a robust method for identifying substance use. Hair captures a comprehensive record of drugs and alcohol by embedding biomarkers within the hair's growing strands. When retrieved near the scalp, it can offer an approximately three-month detection period for substances. Collecting hair is straightforward, potentially tamper-resistant, and convenient for shipping.
A sample measuring 1.5 inches, with about 200 hair strands (similar in size to a #2 pencil) near the scalp, yields 100mg, which is optimal for screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a 150mg sample is advisable. We suggest using a jeweler’s scale to weigh the specimen. In the absence of scalp hair, an equivalent quantity of body hair is acceptable. References to head hair pertain exclusively to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The processing of a drug test result in a laboratory consists of four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first step, where the sample is integrated into the laboratory system, ensuring it was properly sealed and shipped. A random LAN (Laboratory Accessioning Number) is assigned, and any extra data entry not facilitated by an electronic chain of custody system is completed.
Screening is a preliminary assessment for substances of abuse. Though a cost-efficient way to exclude drug use in most samples, a positive result requires confirmation for court acceptance. Any samples testing positive during Screening need a secondary confirmation.
If Screening indicates a probable positive, additional hair is used from the sample for Extraction. During this phase, drugs are removed from hair at lower concentrations than in methods like urine or oral fluid, making hair drug testing a challenging methodology to execute.
Any positive result from Screening is confirmed using GC/MS, GC/MS/MS or LC/MS/MS. Before confirmation, samples that are presumptively positive are washed as required. The lab process from Accessioning through Confirmation adheres to the CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 standards accreditation.
