Recognized as a significant method for identifying substance usage, hair testing is revered for capturing a prolonged record of drugs and alcohol, with biomarkers embedded in hair strands as they grow. A sample taken near the scalp can reveal approximately a 3-month window for detecting alcohol and drugs. Collecting hair is straightforward, hard to tamper with, and convenient for shipping.
A sample measuring 1.5 inches, consisting of nearly 200 hair strands (roughly the thickness of a #2 pencil) from the scalp, yields 100mg, the preferred quantity for screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, a 150mg sample is advised. We advocate using a jeweler’s scale to weigh the sample. If scalp hair is not an option, an equal volume of body hair can be collected. In the context of head hair, we refer specifically to scalp hair. The term body hair encompasses all other forms of hair (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning constitutes the initial stage of integrating a sample into a lab's system. This step verifies the sample's proper sealing and shipment, issues a random LAN (Laboratory Accessioning Number), and completes any missing data not entered through an electronic chain of custody system.
Screening entails a preliminary, rapid assessment for drug abuse. Although Screening is a budget-friendly means to exclude drug consumption in most cases, a positive result requires confirmation to hold up in court. Samples testing presumptively positive in Screening necessitate a follow-up confirmation.
Should a sample show a presumptive positive in the Screening phase, further hair is extracted from the original specimen and set up for Extraction. During Extraction, drugs are isolated from hair at much lower concentrations compared to other techniques (e.g., urine or oral fluid), explaining why hair drug testing is deemed the most challenging methodology.
Confirmation of any assumed positive Screening result occurs through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleansed beforehand if needed. The full laboratory course from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and the accreditation per ISO / IEC 17025 standards.

Limitations:
