Hair analysis has emerged as an effective means for identifying drug and alcohol consumption. Hair retains a comprehensive record of alcohol and drug use by capturing markers within the fibers of the hair that grows. When taken near the scalp, hair can offer a detection period of roughly up to 90 days for alcohol and drugs. Hair is easy to collect, challenging to tamper with, and simple to transport.
A 1.5-inch hair sample consisting of about 200 strands (approximately the thickness of a #2 pencil) nearest the scalp will provide 100mg of hair, which is the preferable sample size for evaluation and validation. For tests including EtG, additional screens, and/or more than 10 panels, a 150mg sample is advisable. It's suggested to weigh the sample using a jeweler’s scale. If scalp hair isn’t available, a similar quantity of body hair may be used. By head hair, we mean only scalp hair. Body hair signifies all other types (e.g., facial, axillary).
Process Synopsis
The key procedures in processing a test result in the lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the primary processing of a sample into the lab's system. It involves checking that the sample was sealed and sent correctly, assigning it a random LAN (Laboratory Accessioning Number), and completing any further data entry not provided through an electronic chain of custody.
Screening comprises an initial rapid examination for substance abuse. Screening is a cost-efficient method for dismissing drug use in most samples, but a positive result needs validation to be permissible in court. Samples that test presumptively positive during Screening need an additional confirmation.
If a sample tests presumptively positive in the Screening stage, more hair is taken from the initial sample and prepared for Extraction. In Extraction, drugs are extracted from the hair at a much lower concentration than other methods (like urine or oral fluid), making hair drug testing the most challenging to perform.
Confirmation of any positive Screening result is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The complete lab process from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO/IEC 17025 standards.
