Hair analysis is now recognized as an effective method for identifying drug and alcohol consumption. Hair captures a comprehensive timeline of substance use, embedding biomarkers within the strands as they grow. When trimmed nearest to the scalp, a hair sample can reveal drug or alcohol consumption up to about 90 days prior. The collection process is straightforward, the samples are quite resistant to tampering, and transporting them is uncomplicated.
A hair section measuring 1.5 inches, comprising roughly 200 strands (akin to the thickness of a #2 pencil) adjacent to the scalp, yields 100mg, the preferred amount for both screening and confirmation. For EtG, additional tests, and/or assessments beyond 10 panels, a 150mg portion is recommended. It's advisable to measure the sample on a jeweler’s scale. Should scalp hair not be accessible, an equivalent volume of body hair can be used. The term "head hair" specifically refers to scalp hair, while "body hair" encompasses all other types (such as facial or underarm hair).
Process Overview
The laboratory processing of drug tests encompasses four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step where a sample is entered into the laboratory’s workflow. This phase ensures the sample's proper sealing and shipping, assigns a unique LAN (Laboratory Accessioning Number), and completes any additional records needed beyond an electronic chain of custody system.
Screening involves a preliminary assessment for substance misuse. Although Screening is an economical method to eliminate drug use in most cases, results that are positive require further confirmation for legal validity. Any sample indicating a presumptive positive outcome in the Screening phase necessitates a subsequent confirmation step.
In instances of a presumptive positive during Screening, additional hair is extracted from the initial sample for the Extraction phase. Here, substances are isolated from hair at much lower concentrations compared to methods like urine or saliva analysis, which explains the complexity of hair drug testing.
Positive Screening findings are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positives are cleaned before undergoing confirmation if necessary. The complete laboratory workflow, from Accessioning to Confirmation, is subjected to the rigorous standards of both the CAP (College of American Pathologists) Hair accreditation and the ISO / IEC 17025 certifications.
Advantages of hair drug testing:
Limitations:
Note: Although often termed as "hair follicle tests", the analysis focuses on the hair strand rather than the follicle beneath the skin.
