Recognized as an effective method for identifying drug and alcohol consumption, hair testing offers a comprehensive timeline of substance use by encapsulating biomarkers within the hair strand's fibers. When cut near the scalp, it can detect substances for up to 90 days. The collection process is straightforward, challenging to tamper with, and facilitates easy transportation.
A sample measuring 1.5 inches, consisting of around 200 hair strands (comparable to the girth of a #2 pencil) nearest to the scalp, yields 100mg of hair, optimal for both screening and confirmation procedures. For testing EtG and/or more than 10 panels, a specimen of 150mg is advised. Utilizing a jeweler’s scale for weighing the sample is recommended. In cases where scalp hair is absent, a similar amount of body hair may be substituted. References to head hair specifically indicate scalp hair. On the other hand, body hair includes all other varieties (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four principal steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is preliminarily processed into the lab's system. This covers ensuring the sample's seal and shipment integrity, assigning a unique LAN (Laboratory Accessioning Number), and supplementing any data entry absent from an electronic chain of custody system.
Screening acts as a preliminary check for substances of abuse. Although cost-effective for negating drug presence in most samples, a positive screening status mandates confirmation for court acceptance. All presumptive positive samples from Screening necessitate further confirmation.
Any sample with a presumptive positive status in Screening leads to additional hair extraction from the original specimen for the Extraction phase. Here, the concentration of drugs extracted from hair is lower than in other methods (e.g., urine or oral fluid), underscoring the complexity of hair drug screening.
Confirmation of any screening positive result employs GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples receive a wash, if necessary, before confirmation. The end-to-end lab process from Accessioning to Confirmation undergoes evaluation under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
