Hair testing is regarded as an effective method for identifying drug and alcohol consumption. Hair captures a record of alcohol and drug usage by embedding biomarkers within the hair strand as it grows. When sampled near the scalp, hair can indicate drug and alcohol presence over an approximate 3-month duration. Hair collection is straightforward, relatively resistant to tampering, and simple to transport.
A 1.5-inch section comprising roughly 200 hair strands (comparable in width to a #2 pencil) cut near the scalp will result in 100mg of hair, which is the optimal amount for testing. For EtG, additional tests, or panels beyond 10, 150mg of hair is suggested. It’s advisable to weigh the hair sample using a jeweler’s scale. If scalp hair cannot be acquired, an equal volume of body hair may be obtained. "Head hair" specifically pertains to scalp hair, whereas "body hair" encompasses all other categories of hair (such as facial and axillary).
Process Overview
There are four primary steps in the lab analysis of a drug test result: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial integration of a sample into a lab’s database. This step involves confirming the sample was properly sealed and shipped, attaching a unique LAN (Laboratory Accessioning Number), and entering any necessary additional data not captured by an electronic chain of custody procedure.
Screening performs an initial rapid assessment for illicit drugs. While Screening is an efficient approach for excluding drug usage in most samples, a positive result must be verified for legal admissibility. Any samples with a presumptive positive in Screening must undergo secondary confirmation.
If a sample is presumptive positive during Screening, more hair is extracted from the initial collection for the Extraction process. During Extraction, drugs are separated from the hair at a significantly lower concentration than other methods (such as urine or oral fluid), justifying why hair drug analysis is the most challenging procedure to execute.
Positive results from the initial screening are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples get washed before confirmation as needed. The complete lab procedures ranging from Accessioning to Confirmation are subject to review under the CAP (College of American Pathologists) Hair guidelines and compliance with ISO / IEC 17025 standards.
