Urine| Hair Follicle | Oral Fluid | Blood | ETG
Hair analysis has emerged as a robust method for detecting drug and alcohol consumption. Hair captures a long-term record of substance use by retaining biomarkers within the fibers of actively growing strands. When collected near the scalp, hair offers a detection window that can extend up to roughly three months for alcohol and drugs. The collection process is straightforward—collection is uncomplicated, tampering is challenging, and shipment is convenient.
A sample measuring 1.5 inches, using approximately 200 strands (resembling the thickness of a #2 pencil) nearest the scalp, will yield 100mg of hair, which is ideal for both screening and confirmation. For EtG, additional tests, or more than 10 panels, a 150mg sample is advisable. Using a jeweler’s scale is recommended for weighing the specimen. Should scalp hair be unavailable, an equivalent amount of body hair is sufficient. References to head hair mean scalp hair only, whereas body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of drug test results encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning starts with initial sample processing into a lab’s system. This step involves ensuring the sample is properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any additional manual entry not handled by an electronic chain of custody system.
Screening consists of a rapid preliminary check for drugs of abuse. While an economical way to eliminate drug use in most samples, a positive screening outcome must be confirmed for court admissibility. Presumptive positives found in Screening require additional confirmation.
If Screening indicates a presumptive positive, additional hair is taken from the specimen for Extraction. This step involves removing drugs from hair at lower concentrations than other methods (e.g., urine or oral fluid), making hair drug testing particularly challenging.
Positive screening results undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives are washed before confirmation as necessary. The complete laboratory workflow, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:

Note: Despite the term "hair follicle tests", the examination focuses on analyzing the hair strand and not the follicle beneath the scalp.
