Lately, hair follicle drug tests have become increasingly popular for drug testing. Employers, courts, and substance abuse experts are opting for this method over the traditional urine test. These tests are preferred for their longer detection periods of up to 90 days, strict observed collection, reducing chances of tampering. However, the urine test remains the most precise when screening for drug use within the past 5 days.

Hair testing is now recognized as a robust technique for detecting alcohol and drug use. Hair captures long-term histories of substances by embedding biomarkers within the fiber structure of the hair strand as it grows. When hair is sampled near the scalp, it offers a detection period of up to roughly three months for alcohol and drugs. Hair is easy to gather, generally hard to tamper with, and simple to transport.
A sample measuring 1.5 inches of about 200 hair strands (approximately comparable to a #2 pencil's thickness) closest to the scalp provides 100mg, an optimal amount for screening and confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, a 150mg specimen is advised. It's best to weigh the specimen using a jeweler’s scale. If scalp hair isn't obtainable, a similar quantity of body hair may be gathered. 'Head hair' pertains specifically to scalp hair. 'Body hair' refers to any other hair types (such as facial, axillary, etc.).
Process Overview
The key steps in the lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial incorporation of a sample into the laboratory's system. It encompasses the verification of the sample's proper sealing and shipping, the assignment of a random LAN (Laboratory Accessioning Number), and the completion of additional data entry not covered by an electronic chain of custody system.
Screening entails a preliminary swift assessment for abused substances. While it is a resource-efficient method to preclude drug usage for most samples, a positive finding must be confirmed before it can stand up in court. Samples with a presumptively positive result in Screening necessitate secondary confirmation.
Upon a presumptive positive outcome during Screening, extra hair is extracted from the original specimen for Extraction. Drugs are isolated from hair in this phase at substantially lower concentrations than other methods (e.g., urine or oral fluid), underscoring the complexity of hair drug screening.
Confirmation of any positive screening result is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. Each presumptive positive sample undergoes necessary washing before confirmation. The comprehensive lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
