Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. Hair gives an extended timeline of substance use by embedding biomarkers within the strands as they grow. When obtained near the scalp, it can reflect a drug or alcohol detection span of up to three months. Hair collection is straightforward, relatively resistant to tampering, and easy to transport.
A sample measuring 1.5 inches and comprising around 200 hair strands (similar in size to a #2 pencil) nearest to the scalp yields 100mg, which is optimal for both screening and confirmation tests. For EtG, additional tests, and tests beyond 10 panels, 150mg is advisable. We suggest using a jeweler's scale for weighing the sample. In cases where scalp hair is inaccessible, a similar amount of body hair can be used. "Head hair" signifies scalp hair exclusively, while "body hair" includes all other hair types (e.g., facial, axillary).
Process Overview
The laboratory processing of a drug test involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step where the sample is integrated into the lab’s system, which includes verifying the proper sealing and shipping of the sample, allocating a unique LAN (Laboratory Accessioning Number), and completing any necessary data entry absent from an electronic chain of custody.
Screening is a preliminary assessment for drug presence. While efficient in eliminating drug use suspicions from most samples, a positive screen must be confirmed for legal acceptance. Presumptive positives in Screening require a follow-up confirmation.
For presumptive positives found during Screening, additional hair is extracted from the original sample for the Extraction phase. This phase involves retrieving drugs from hair at a lower concentration than other methods (e.g., urine or oral fluid), which makes hair drug screening a challenging process.
Confirmation of any positive screening is carried out using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples marked as presumptive positives undergo a washing process before confirmation, as necessary. The entire laboratory process from Accessioning to Confirmation undergoes review according to both CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Despite being commonly called "hair follicle tests," these tests actually assess the hair strand, not the follicle beneath the scalp.
