Hair testing has emerged as a vital resource in identifying drug and alcohol consumption. Hair captures a chronic history of substance use by embedding biomarkers within the fibers of the growing hair. When collected near the scalp, hair can reflect a drug and alcohol detection window of up to roughly three months. The collection process is straightforward, resists tampering, and is easily transportable.
A 1.5-inch segment of about 200 hair strands (approximately the width of a #2 pencil) near the scalp yields 100mg, the optimal sample for both screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, 150mg of the sample is advised. Using a jeweler’s scale for weighing the sample is recommended. If scalp hair is not available, a comparable quantity of body hair may be gathered. When referencing head hair, it specifically means scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
Four key stages are involved in a laboratory's processing of drug test results: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of incorporating a sample into a lab’s system, including ensuring proper sealing and shipping, generating a random LAN (Laboratory Accessioning Number), and completing any extra data entry not already provided by an electronic chain of custody system.
Screening provides an initial rapid evaluation for drugs of abuse. Although Screening is an economical way to exclude drug usage in most samples, a positive screening must be confirmed to be valid in legal settings. Samples that yield a presumptively positive result in Screening necessitate secondary confirmation.
If a sample indicates a presumptive positive during Screening, additional hair is extracted from the initial specimen and prepared for Extraction. In this phase, drugs are extracted from hair at significantly lower concentrations than other methods (such as urine or oral fluid), making hair drug screening the most challenging methodology.
Positive screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptively positive samples undergo washing before confirmation as required. The entire lab procedure, from Accessioning to Confirmation, is assessed under the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Though commonly called "hair follicle tests", the test evaluates the hair strand and not the hair follicle under the scalp.
