Hair analysis is recognized as an effective approach for identifying drug and alcohol consumption. Hair captures a prolonged history of substance use by embedding biomarkers within the strands as it grows. When gathered from near the scalp, hair can reveal a detection period of up to around three months for substances like alcohol and drugs. Collecting hair is straightforward, hard to tamper with, and easy to transport.
A sample measuring 1.5 inches with approximately 200 hair strands (roughly the size of a #2 pencil) taken near the scalp yields 100mg of hair, which is the optimal quantity for evaluation and verification. For tests with EtG add-ons and/or exceeding 10 panels, 150mg of the sample is advised. Utilizing a jeweler’s scale to weigh the sample is suggested. If scalp hair is not accessible, an equivalent portion of body hair may be collected. When we mention head hair, it pertains only to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The lab analysis of a drug test outcome involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial entry of a sample into the lab's system. This step includes ensuring the sample is appropriately sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry absent from an electronic chain of custody system.
Screening includes a preliminary swift assessment for substances of abuse. Although Screening is an economical method to exclude drug usage for most samples, a positive result requires confirmation for court admissibility. Samples that test presumptively positive during Screening need additional confirmation.
If a sample shows presumptive positivity in the Screening phase, further hair is extracted from the sampled specimen and prepared for Extraction. During this stage, drugs are extracted from hair at considerably lower concentrations compared to other methods (e.g., urine or oral fluid), which is why hair drug testing is among the most challenging methods to administer.
Confirmation for positive screening results is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positivity are cleansed before confirmation as necessary. The complete lab process, from Accessioning to Confirmation, is inspected under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Though often called "hair follicle tests", the analysis evaluates the hair strand rather than the follicle beneath the scalp.
