Hair analysis is recognized as an effective means for identifying drug and alcohol usage. By encapsulating biomarkers within the growing hair fibers, hair offers an extended history of substance use. Hair gathered near the scalp delivers a detection span of around three months for alcohol and drugs. It's easy to collect, tough to tamper with, and simple to send.
A 1.5-inch section of approximately 200 hair strands (comparable to a #2 pencil's width) nearest to the scalp yields 100mg, the perfect amount for testing. For EtG, additional analyses, and/or tests beyond 10 panels, a 150mg sample is advisable. It's best to measure the sample using a jeweler’s scale. If scalp hair is not available, an equivalent amount of body hair can be used. When mentioning head hair, it specifically means scalp hair. Body hair includes all other types (facial, armpit, etc.).
Process Overview
The laboratory assessment of a drug test consists of four distinct phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a specimen into a lab's framework. It includes confirming that the sample is properly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data required that is not provided by an electronic chain of custody.
Screening serves as a preliminary test for substances of abuse. Although Screening is an economical solution for eliminating drug use in most specimens, a positive result must be verified to be admissible in legal scenarios. Any samples that return a presumptive positive in Screening need further confirmation.
If the Screening phase indicates a presumptive positive, more hair is taken from the original sample for the Extraction process. Here, drugs are extracted from hair at lower concentrations than in other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug testing.
Validation of any positive screening result is performed using GC/MS, GC/MS/MS or LC/MS/MS. Any presumptive positive samples undergo washing before confirmation as necessary. The entire process from Accessioning through to Confirmation is evaluated under CAP (College of American Pathologists) Hair guidelines and accredited to ISO / IEC 17025 standards.

Note: Although commonly called "hair follicle tests", the analysis itself focuses on the hair strand, not the follicle beneath the scalp.
