Hair analysis is recognized as an effective method for identifying the use of drugs and alcohol. It offers a prolonged timeline of substance usage by capturing biomarkers within the strands as they grow. When the hair is sampled near the head, it can reveal substance use over an estimated 3-month span. It is straightforward to collect, challenging to tamper with, and convenient for transport.
Sampling a 1.5-inch section of about 200 hair strands (approximately the diameter of a #2 pencil) from near the scalp equates to 100mg, the optimal amount for testing and verification. For EtG tests, additional panels, or those exceeding 10 panels, 150mg of the sample is advisable. We suggest utilizing a jeweler’s scale for specimen measurement. If scalp hair is not obtainable, a similar quantity of body hair can be used. By head hair, we specifically mean scalp hair. Body hair pertains to all other hair varieties (facial, axillary, etc.).
Process Overview
The four fundamental phases in the lab processing of a drug test result entail Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the primary processing of a specimen into a lab's system. This includes verifying the proper sealing and shipping of the sample, generating a unique LAN (Laboratory Accessioning Number), and performing any additional data input absent from an electronic chain of custody system.
Screening serves as an initial brief assessment for drug misuse. Although Screening is a budget-friendly method to dismiss drug use in most samples, a positive screen must be validated for courtroom acceptance. Any specimens that show a presumptive positive during Screening need further confirmation.
Should a specimen be considered presumptively positive at the Screening stage, more hair is taken from the original sample for preparation during Extraction. Here, drugs are removed from hair at far lower concentrations compared to other techniques (e.g., urine or oral fluid), signifying that hair drug screening is the most intricate methodology to conduct.
Verification of any positive Screening outcome is executed through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo a washing process before confirmation if necessary. The full laboratory method from Accessioning through Confirmation is appraised under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
