Typically, 1.5 to 2 inches of hair on the head or other body hair can be tested for substances like drugs and alcohol/ETG, with various customized options available.
Hair follicle drug tests have grown in prevalence for substance screening in recent years. They are increasingly mandated by employers, courts, and substance abuse experts over traditional urine tests. This method benefits those with zero-tolerance policies, offering an extended detection window of up to 90 days, collected under observation and challenging to manipulate. For recent use, within 5 days, urine tests remain more precise.

Hair testing is regarded as an effective method for identifying drug and alcohol consumption. It provides an extended history of substance use by capturing biomarkers within the hair strand fibers. When sampling near the scalp, hair can reveal drug and alcohol usage over a period of up to three months. Hair collection is straightforward, difficult to tamper with, and easy to transport.
A sample of 1.5 inches, comprising around 200 hair strands (similar in size to a #2 pencil) closest to the scalp, yields 100mg of hair, which is ideal for screening and confirming. For tests such as EtG, additional panels over 10, 150mg of the sample is suggested. Using a jeweler's scale to weigh the specimen is advisable. If scalp hair isn't accessible, a comparable quantity of body hair can be collected. When discussing head hair, we specifically mean scalp hair only. Body hair includes all other types of hair (facial, axillary, etc.).
Process Overview
The laboratory process for a drug test result includes four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial sample processing in the lab’s system. This step ensures that the sample was properly sealed and shipped, assigns a unique LAN (Laboratory Accessioning Number), and completes any missing data from an electronic chain of custody system.
Screening is a preliminary evaluation for substance usage. Although Screening is an economical method to exclude drug use for most samples, a positive screen must be confirmed for legal admissibility. Samples testing presumptively positive during Screening require additional confirmation.
In cases of presumptively positive results from Screening, additional hair is extracted from the sample for further Extraction. Here, drugs are isolated from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug screening one of the most challenging methods to execute.
Confirmation for any positive Screening result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing as necessary before confirmation. The complete lab process from Accessioning to Confirmation is conducted under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
