Hair testing is now viewed as an effective method for detecting drug and alcohol consumption. Hair records a prolonged timeline of alcohol and drug usage by encapsulating biomarkers within the fibers of the hair as it grows. When taken near the scalp, hair can offer a detection window of up to about 3 months for alcohol and other substances. It's easy to gather, hard to tamper with, and straightforward to transport.
A 1.5-inch portion of approximately 200 hair strands (roughly the thickness of a #2 pencil) nearest to the scalp will provide 100mg of hair, the optimal sample for both screening and confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, 150mg of the sample is suggested. Using a jeweler’s scale for weighing the sample is advised. If scalp hair isn’t available, a comparable quantity of body hair can be collected. Head hair specifically refers to scalp hair, whereas body hair includes any other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result includes four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial intake of a sample into the laboratory’s framework. This step ensures the sample was correctly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and concludes any remaining data entry omitted from an electronic chain of custody procedure.
Screening provides an initial rapid assessment for drug abuse. Though Screening offers a cost-saving approach to eliminating drug usage in most cases, any positive result from Screening must be confirmed for legal admissibility. Screening-determined presumptive positives necessitate follow-up confirmation.
When a sample shows a presumptive positive in the Screening phase, additional hair is extracted from the original sample and prepped for Extraction. In this phase, drugs are isolated from hair at notably lower concentrations than other methods (such as urine or oral fluid), making hair drug testing the most complex technique to conduct.
Confirmation of positive Screening outcomes is carried out using GC/MS, GC/MS/MS, or LC/MS/MS technologies. All samples indicating presumptive positives undergo washing before confirmation if needed. The full laboratory procedure from Accessioning to Confirmation is examined under the CAP (College of American Pathologists) Hair certification and the ISO / IEC 17025 standard accreditation.
Advantages of hair drug testing:
Limitations:
Note: Although commonly referred to as "hair follicle tests", the examination is conducted on the hair strand itself rather than the follicle beneath the scalp.
