Hair Follicle Drug Testing - Thor, IA

What it is, How it works

Hair testing has emerged as a potent method for identifying drug and alcohol consumption. Hair captures a prolonged history of drug and alcohol use by embedding biomarkers within the texture of the developing hair strand. When obtained near the scalp, hair can offer up to a three-month detection range for drugs and alcohol. Hair is straightforward to gather, relatively hard to tamper with, and simple to transport.

A sample of 1.5 inches containing about 200 hair strands (comparable to a #2 pencil) nearest to the scalp yields 100mg of hair, which is the ideal sample for screening and confirmation. For EtG, add-ons, and/or screenings beyond 10 panels, it’s advised to use 150mg of the specimen. It's recommended to weigh the specimen using a jeweler’s scale. Should scalp hair be unavailable, an equivalent quantity of body hair can be utilized. In referencing head hair, we are referring exclusively to scalp hair. Body hair encompasses other types (facial, axillary, etc.).

Process Overview

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

Accessioning encompasses the initial processing of a sample into the laboratory's system. This process includes verifying the sample's proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not covered by an electronic chain of custody system.

Screening represents an initial rapid check for drug abuse. While Screening is an economical approach to eliminate drug use in the majority of samples, any positive screening results require confirmation to be legally admissible. Samples that show presumptive positives in Screening necessitate a secondary confirmation.

When a sample shows a presumptive positive in the Screening phase, additional hair is extracted from the original sample and prepared for Extraction. In this stage, drugs are extracted from hair at noticeably lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening a highly complex methodology.

Any positive screening outcomes undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleansed before confirmation when necessary. The entire lab process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug screenings can reveal drug use up to 90 days, whereas urine screenings have a shorter detection span.
• Difficult to circumvent: Cheating a hair drug test is notably challenging, ensuring more precise outcomes.
• Offers historical insight: It can trace a pattern of drug use over time, rather than just recent usage.

Limitations:

• Incapable of detecting recent use: Drugs take roughly 5-7 days to become traceable in hair.
• Expense: Hair drug screenings generally cost more than other drug testing methods.
• Outcome variations: Factors like hair color and personal differences in hair growth can influence drug metabolite concentrations in hair.

Note: Although commonly termed "hair follicle tests", the test scrutinizes the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

When comparing hair follicle testing to traditional urine testing in Thor, IA, hair tests offer enhanced detection accuracy. The method is superior in identifying drug use over extended periods. Employers and legal entities benefit from its ability to provide a clearer understanding of a person's substance use history, beyond the limitations of short-term detection in urine tests.

Hair testing’s reliability underscores its importance in environments demanding strict adherence to drug policies. It lessens the chance of tampering, ensuring that the results are trustworthy, unlike urine samples which are sometimes subject to manipulation.

Extended Detection Window

The extended detection window of up to 90 days in hair follicle testing offers a comprehensive view of an individual’s drug use. In Thor, IA, this means employers can better assess applicants or current employees, gaining insight into their substance habits far beyond the confines of short-term tests.

This long-term detection capability is particularly useful for companies aiming to maintain a drug-free workplace. It goes beyond immediate detection, looking at a prolonged period to ensure a safe and compliant work environment.
