Hair analysis has emerged as a robust method for detecting drug and alcohol consumption. Hair offers a long-term record of alcohol and drug usage by encapsulating biomarkers within the fibers of the hair as it grows. When samples are taken near the scalp, hair can reveal up to about a 3-month timeframe for detecting alcohol and drugs. Hair collection is straightforward, less prone to tampering, and easy to transport.
A 1.5-inch segment of approximately 200 hair strands (roughly the diameter of a #2 pencil) nearest to the scalp provides 100mg of hair, the optimal amount for both screening and confirmation. For tests involving EtG, additional panels, or above 10 panels, 150mg is advised. It's suggested to weigh the hair sample using a jeweler's scale. If scalp hair is not an option, a comparable quantity of body hair may be used. When we refer to head hair, we only mean scalp hair. Body hair encompasses all other types (like facial, axillary, etc.).
Process Overview
The key stages in processing a drug test result in the lab include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary handling of a sample within the laboratory's setup. This step consists of verifying the sample's seal and proper shipping, assigning a unique LAN (Laboratory Accessioning Number), and completing additional data entry absent in an electronic chain of custody system.
Screening is an initial, rapid evaluation for the presence of drug abuse. Although Screening is an economical method to dismiss drug use in most samples, a screen result must be confirmed for it to be legally admissible. Samples that test presumptively positive during Screening must undergo a second confirmation test.
If a sample tests presumptively positive during the Screening phase, further hair is extracted from the original sample and readied for Extraction. In this phase, drugs are isolated from hair at significantly lower concentrations than other techniques (such as urine or oral fluids), making hair drug testing a complex procedure.
Any positive Screening result is validated using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The complete laboratory workflow from Accessioning through Confirmation is audited under the CAP (College of American Pathologists) Hair designation and conforms to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: While often referred to as "hair follicle tests", the actual test analyzes the hair strand, not the follicle underneath the scalp.
