Recognized as a significant tool, hair testing is utilized to detect substance use, capturing a comprehensive record of drug and alcohol consumption by embedding biomarkers in the hair as it grows. When samples are obtained near the scalp, hair offers a detection window of roughly 3 months for various substances. Collection is straightforward, tampering is challenging, and transportation is easy.
A hair sample measuring 1.5 inches with approximately 200 strands (comparable to the width of a #2 pencil) from the closest point to the scalp yields about 100mg, which is the optimal sample size for assessment and validation. However, for EtG, additional tests, or those exceeding 10 panels, a specimen of 150mg is advisable. It is best to weigh the hair sample using a jeweler's scale. In cases where scalp hair is not available, an equivalent amount of body hair can be used. The term "head hair" specifically refers to scalp hair, while "body hair" pertains to all other types (such as facial, axillary, etc.).
Process Overview
The drug testing result process comprises four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a laboratory's system, ensuring the sample was correctly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any outstanding data entry that is not already part of an electronic chain of custody system.
Screening consists of an initial evaluation to detect abusive substances. While it is an economical method to rule out drug use in the majority of samples, a positive screening outcome necessitates confirmation for legal acceptance. Samples with preliminary positive results in Screening require a secondary Confirmation step.
For samples indicating a positive result in Screening, additional hair is utilized from the initial sample for the Extraction stage. Here, the substance extraction from hair occurs at much lower concentrations than other methods (like urine or oral fluid), thereby making hair drug testing the most complex method to perform.
Confirmation for any positive screening outcomes is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to Confirmation, all samples with presumption of positive results are washed if necessary. The complete laboratory procedure, from Accessioning to Confirmation, is scrutinized under both the College of American Pathologists (CAP) Hair designation and in accordance with ISO / IEC 17025 standards.
