Hair analysis is regarded as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged history of substances through biomarkers trapped in the strands as they grow. When taken near the scalp, a sample can provide insight into alcohol and drug use for up to approximately three months. Hair collection is straightforward, hard to tamper with, and simple to transport.
A 1.5-inch sample containing roughly 200 hair strands (similar in size to a #2 pencil) near the scalp yields 100mg, which is optimal for screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, a 150mg sample is advocated. It's advisable to use a jeweler’s scale for weighing the sample. Should scalp hair be inaccessible, a comparable quantity of body hair may be gathered. When mentioning head hair, we imply scalp hair solely. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The drug testing process in laboratories involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning starts with the incorporation of a sample into the laboratory system. This phase ensures proper sealing and shipment of samples, assigns a random LAN (Laboratory Accessioning Number), and finalizes any additional data input absent from an electronic chain of custody system.
Screening provides a preliminary test for drugs of abuse. Though it is a cost-effective means to rule out drug usage in most samples, a positive result requires subsequent confirmation for legal admissibility. Presumptive positives from Screening necessitate an additional verification.
Presumptive positives identified during Screening are further analyzed through Extraction by retrieving more hair from the original specimen. Drugs are isolated at lower concentrations in hair compared to other methods (e.g., urine or saliva), making hair screening the most challenging form of testing.
Confirmation occurs through GC/MS, GC/MS/MS, or LC/MS/MS for positive screens. All presumptive positive samples undergo washing before confirmation as necessary. The full laboratory procedure, from Accessioning to Confirmation, is overseen under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Often termed "hair follicle tests", the analysis itself targets the hair strand rather than the hair follicle beneath the scalp.
