Recognized as a formidable method for identifying drug and alcohol consumption, hair analysis offers a prolonged timeline of substance use by embedding biomarkers within the strands of hair. By gathering samples near the scalp, hair has the potential to reveal up to a 3-month history of alcohol and drug use. The process of obtaining hair samples is straightforward, tampering is challenging, and shipping is hassle-free.
A minimum of 1.5 inches, equating to roughly 200 strands (comparable to a #2 pencil thickness) nearest the scalp, yields 100mg, ideal for testing and validation. For EtG, supplemental tests, or extensive panel tests exceeding 10, it's advisable to obtain 150mg. Accurate measurement of the sample can be done using a jeweler's scale. Should scalp hair be inaccessible, a similar weight in body hair is acceptable. "Head hair" specifically denotes scalp hair, while "body hair" encompasses all other types (including facial, axillary, etc.).
Overview of the Procedure
The drug test result analysis in the laboratory comprises four crucial phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary stage where the sample is registered into the lab's system. It involves ensuring the sample's secure sealing and delivery, assigning a LAN (Laboratory Accessioning Number), and completing any further data input not covered by an electronic chain of custody system.
Screening offers an initial, swift assessment for drug presence. Although cost-efficient for excluding drug usage across most samples, a positive result in Screening requires validation for legal admissibility. Presumptive positives in Screening necessitate confirmation through additional testing.
In instances of presumptive positive results during Screening, more hair is retrieved from the initial sample for the Extraction phase. Here, drug compounds are isolated from the hair at much lower concentrations than in other methods like urine or oral fluid testing, highlighting the complexities involved in hair drug analysis.
GC/MS, GC/MS/MS, or LC/MS/MS mechanisms are employed to confirm positive results found during Screening. Necessary washing of all presumptive positive samples occurs before confirmation. The entire process, from Accessioning through Confirmation, is scrutinized under CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 accreditation standards.
Benefits of hair drug analysis:
Drawbacks:
Clarification: Often termed "hair follicle tests", these assessments actually evaluate the hair strand rather than the follicle beneath the scalp.
