Recognized as a robust method, hair testing efficiently identifies drug and alcohol consumption. It offers an extensive history of substance use by encapsulating biomarkers within the hair's fibers. When collected near the scalp, hair can provide an approximate 3-month detection frame for drugs and alcohol. It is easy to gather, somewhat resistant to tampering, and simple to transport.
Collecting a 1.5-inch segment of about 200 hair strands (comparable to the dimension of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal sample for both screening and confirmation. For EtG, additional tests, and tests beyond 10 panels, a collection of 150mg is advisable. It is recommended to measure the hair on a jeweler’s scale. If scalp hair is unobtainable, an equivalent amount of body hair can be used. The term "head hair" refers specifically to scalp hair, while "body hair" encompasses all other hair types (such as facial and axillary hair).
Process Overview
The laboratory processing for drug test results involves four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning integrates the sample into the lab’s system initially. This step confirms the proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and finalizes any additional data entry absent from the electronic chain of custody.
Screening serves as a preliminary check for drug abuse. Though cost-effective for excluding drug usage in most samples, a positive screen necessitates confirmation for court acceptance. Samples with presumptive positive results in Screening require a second confirmation.
Should a sample have a presumptive positive result in Screening, further hair is extracted from the original sample to prepare for Extraction. In this step, drugs are extracted from hair at much lower concentrations than in other methods (like urine or oral fluid), making hair drug screening particularly challenging.
Positive screening results undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleaned before confirmation when necessary. The whole lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Though occasionally termed "hair follicle tests", the analysis evaluates the hair strand rather than the follicle beneath the scalp.
Hair follicle testing boasts several advantages over traditional urine tests in Jewett, TX. Primarily, these tests provide superior detection accuracy and reliability in identifying past drug usage.
