Hair analysis has emerged as an effective means for identifying drug and alcohol consumption. Hair strands offer a prolonged record of alcohol and drug intake by capturing biomarkers within their fibers. When taken from near the scalp, hair can reflect up to a 3-month period of alcohol and drug use. It is easy to gather, relatively tamper-resistant, and straightforward to transport.
A sample measuring 1.5 inches with about 200 hair strands (comparable to the size of a #2 pencil) near the scalp yields 100mg of hair, the optimal quantity for both screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, at least 150mg of hair is advisable. The sample should be weighed on a jeweler's scale. If scalp hair is not present, a comparable amount of body hair can be used. When mentioning head hair, it specifically refers to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The core steps in laboratory drug test evaluation include Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the preliminary integration of a sample into the lab’s database. This process ensures the sample's proper sealing and dispatch, assigns a random LAN (Laboratory Accessioning Number), and completes any necessary data entry not managed by an electronic custody framework.
Screening is a swift preliminary evaluation for substances of abuse. Though economical, a Screening result needs confirmation to hold legal admissibility. Presumptively positive samples in Screening necessitate an additional confirmation phase.
Should a sample test presumptively positive during Screening, further hair is extracted from the initial sample and made ready for Extraction. In this phase, substances are extracted from hair at significantly reduced concentrations compared to other methods (such as urine or oral fluid), making hair drug testing particularly challenging.
Verification of any positive Screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Samples marked as presumptively positive undergo washing as required before Confirmation. The complete laboratory workflow from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair criteria and is accredited to ISO / IEC 17025 standards.
