Hair analysis is increasingly recognized as an effective method for detecting drug and alcohol consumption. The strands of hair absorb biomarkers into their fibers as they grow, forming a long-term record of substance use. When taken from near the scalp, hair samples can offer a detection window of up to roughly three months for both alcohol and drugs. Hair is also easy to collect, challenging to tamper with, and straightforward to transport.
A sample size of 1.5 inches from approximately 200 strands of hair (similar in size to a #2 pencil) from the scalp yields 100mg, which is ideal for both screening and confirmation. For in-depth testing such as EtG, add-ons, and/or panels exceeding 10, it is suggested to collect 150mg. We advise using a jeweler's scale to weigh the specimen. Should scalp hair be unavailable, a comparable amount of body hair can be utilized. When discussing head hair, we mean scalp hair specifically. Body hair pertains to all other kinds such as facial or axillary hair.
Process Overview
Processing a drug test result in a lab entails four core steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary stage where a sample is entered into the lab system. This step involves confirming that the sample was securely sealed and shipped, assigning it a unique Laboratory Accessioning Number (LAN), and completing any outstanding data not covered by an electronic chain of custody system.
Screening serves as a preliminary examination for drug presence. While cost-effective for eliminating drug use in most samples, any positive result requires further confirmation to be legally valid. Samples that suggest the presence of drugs during Screening necessitate an additional verification step.
In cases where the Screening indicates a presumptive positive, additional hair from the initial sample is subjected to Extraction. This process removes drugs from hair at lower concentrations than other methods such as urine or oral fluid tests, highlighting the complexity of hair drug screening.
Confirming any positive Screening findings is done through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo a cleansing before confirmation as needed. The complete laboratory procedure from Accessioning to Confirmation is assessed according to both the CAP (College of American Pathologists) Hair guidelines and the ISO / IEC 17025 standards certification.
