Hair analysis has emerged as a robust method for identifying alcohol and drug consumption. The fibers of a growing hair strand capture and retain biomarkers, providing a detailed historical record of substance use. When hair is collected near the scalp, it offers a detection period of up to about three months for alcohol and drugs. Collection is straightforward, tampering is difficult, and shipping is convenient.
Securing a 1.5-inch segment of approximately 200 strands (comparable to the girth of a #2 pencil) nearest to the scalp will yield 100mg, an optimal quantity for evaluation and validation. For EtG, supplementary tests, and tests exceeding 10 panels, a specimen of 150mg is advisable. It's recommended to measure the specimen on a jeweler’s scale. In the absence of scalp hair, a comparable amount of body hair is an alternative. "Head hair" specifically refers to scalp hair, while "body hair" encompasses other types (facial, axillary, etc.).
Process Overview
The process in a laboratory setting for obtaining a drug test outcome encompasses four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning constitutes the initial phase of integrating a sample into a laboratory’s system. This step verifies proper sealing and shipment of the sample, generates a random LAN (Laboratory Accessioning Number), and fulfills any supplementary data entry not facilitated by an electronic chain of custody system.
Screening offers a preliminary check for the presence of illicit drugs. Although Screening is an economical approach to exclude drug usage in most cases, a positive result demands validation to be accepted legally. Presumptive positives in Screening necessitate further confirmation.
Should a sample yield a presumptively positive result during Screening, additional hair is extracted from the original sample for the Extraction phase. In Extraction, drugs are isolated from hair at much lower concentrations than those in other techniques (e.g., urine or oral fluid). This is why hair drug screening is the most challenging methodology.
Confirmation of any positive result from screening is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing prior to confirmation if deemed necessary. The entire process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair guidelines as well as ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Though commonly termed "hair follicle tests," the analysis focuses on the hair strand itself, not the follicle beneath the scalp.
In the debate of hair follicle versus urine testing in Little Black, WI, hair testing reigns supreme with its extended detection span and superior accuracy. While urine tests are commonly used, their short detection window often limits their effectiveness.
