Hair screening is now regarded as a formidable method for identifying the use of drugs and alcohol. Hair serves as a time-extended record of alcohol and drug use by embedding biomarkers within the strands of the developing hair fiber. A sample collected close to the scalp can offer a detection period of nearly three months for both alcohol and drugs. Hair collection is straightforward, relatively tamper-resistant, and convenient for shipping.
A hair strand sample of 1.5 inches representing around 200 strands (approximately matching a #2 pencil's thickness) near the scalp will yield 100mg of hair, which is the optimal sample for both screening and confirmation. For EtG, additional analyses, and/or tests exceeding 10 panels, a specimen weight of 150mg is suggested. Utilizing a jeweler’s scale for weighing the specimen is recommended. If scalp hair is not available, a comparable amount of body hair can be used. The term head hair refers exclusively to scalp hair, while body hair covers all other hair forms (such as facial, axillary, etc.).
Process Overview
The drug test result processing in the laboratory involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the sample's initial integration into a laboratory's system, ensuring the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and finalizing any further data entry not present in an electronic chain of custody system.
Screening offers a preliminary rapid check for substance abuse drugs. Though Screening is an affordable means to exclude drug consumption for most samples, a positive result from Screening necessitates confirmation for legal admissibility. Samples showing presumptive positivity in Screening need additional verification.
For samples indicating a tentative positive during Screening, further hair is extracted from the primary specimen and readied for Extraction. During this stage, drugs are drawn out from hair at significantly lower concentrations than in alternative methodologies (such as urine or oral fluid), making hair drug screening the most challenging technique to administer.
Confirmation for any positive screening outcome is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. Any samples that are presumably positive are cleaned before confirmation as required. The whole laboratory procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair classification and the certification to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
