Hair testing is widely recognized as an effective method for detecting drug and alcohol consumption. It captures long-term alcohol and drug usage by embedding biomarkers within the hair as it grows. By gathering samples near the scalp, hair testing can identify drug and alcohol use over a period of up to three months. Hair collection is straightforward, hard to tamper with, and convenient for transportation.
A 1.5-inch sample consisting of about 200 hair strands (comparable to the thickness of a #2 pencil) near the scalp provides 100mg of hair, which is the optimal amount for both screening and confirmation tests. For EtG testing, additional panels beyond 10, or supplementary testing, 150mg of the sample is preferred. It is advisable to weigh the sample using a jeweler's scale. If scalp hair is not available, an equivalent amount of body hair can be used. Scalp hair refers only to head hair, while body hair encompasses all other types (such as facial, axillary, etc.).
Process Overview
The primary steps in the laboratory processing of a drug testing result include Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is thoroughly integrated into the laboratory’s system, ensuring correct sealing and shipping, assigning a Laboratory Accessioning Number (LAN), and completing any extra information not available through electronic chain of custody systems.
Screening involves an initial evaluation for common drugs of abuse. Although Screening efficiently eliminates drug usage in most cases, court admissibility necessitates confirming positive screens. Any samples that show a presumptive positive result during Screening require further confirmation.
Should a sample indicate a presumptive positive during Screening, more hair is taken from the original sample to proceed with Extraction. At this stage, substances are isolated from hair at lower concentrations compared to other methods (like urine or oral fluid), which contributes to the complexity of hair drug screening.
Confirmation of any positive screening follows through methods such as GC/MS, GC/MS/MS, or LC/MS/MS, with presumptively positive samples being cleaned if needed before confirmation. From beginning to end, the laboratory processes from Accessioning to Confirmation undergo evaluation under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 certification.
