Hair Follicle Drug Testing - Brooks, WI

What it is, How it works

Hair testing is now regarded as a robust method for identifying drug and alcohol usage. Hair captures a prolonged history of alcohol and other substances by encasing biomarkers within the fibers of the developing hair strand. When collected near the scalp, hair can offer up to roughly a 3-month detection period for alcohol and other substances. Hair is straightforward to collect, relatively hard to tamper with, and convenient to transport.

A 1.5-inch hair sample, consisting of roughly 200 strands (comparable to the size of a #2 pencil) nearest to the scalp, will provide 100mg of hair, which is the optimal amount for analysis and verification. For EtG, add-ons, or tests beyond 10 panels, 150mg of the hair sample is advised. We suggest weighing the sample using a jeweler’s scale. If scalp hair isn’t available, an equal quantity of body hair might be gathered. When mentioning head hair, we specifically mean scalp hair. Body hair includes all other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into a lab’s system. This process covers confirming that the sample was properly sealed and forwarded, assigning a random LAN (Laboratory Accessioning Number), and fulfilling any further data entry not supplied by an electronic chain of custody system.

Screening comprises an initial fast assessment for drugs of misuse. Though Screening is a budget-friendly approach to exclude drug use in most samples, a positive screening necessitates confirmation for court admissibility. Any samples indicated as positive during Screening demand secondary confirmation.

If a sample results as positive in the Screening phase, additional hair is drawn from the original sample and prepared for Extraction. In this step, substances are extracted from hair at considerably lower concentrations than in other methods (e.g., urine or oral fluid), rendering hair drug screening the most challenging technique to execute.

Validation of any positive screening outcome is completed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing presumptive positivity are cleaned before validation if necessary. The complete laboratory procedure from Accessioning to Confirmation is monitored according to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug evaluations can identify drug usage for up to 90 days, unlike urine assessments with a briefer detection span.
• Challenge to deceive: Cheating a hair drug test is extremely tough, ensuring more reliable results.
• Delivers historical insights: It can demonstrate a pattern of drug use over an extended period, beyond recent usage.

Limitations:

• Incapable of detecting recent usage: It takes about 5-7 days for drugs to become traceable in hair.
• Expense: Hair drug evaluations typically incur higher costs than other testing approaches.
• Outcome variability: Elements like hair color and individual disparities in hair growth can influence the concentration of drug metabolites in hair.

Note: While commonly termed "hair follicle tests", the analysis actually examines the hair strand, not the follicle below the scalp.
