Hair Follicle Drug Testing - Caledonia, WI

What it is, How it works

Hair analysis is increasingly recognized as an effective method for detecting substance use. Hair archives a long-term record of alcohol and drug consumption by capturing biomarkers within the hair shaft as it grows. When taken near the scalp, it can provide a detection period of up to around three months for alcohol and drugs. Collecting hair is straightforward, less susceptible to tampering, and easy to transport.

A sample measuring 1.5 inches and consisting of about 200 hair strands (roughly the thickness of a #2 pencil) near the scalp will yield 100mg of hair, which is optimal for both screening and confirmation. For EtG or additional tests surpassing 10 panels, 150mg of hair is advisable. We suggest using a jeweler’s scale for precise measurement. If scalp hair is not an option, an equivalent amount of body hair can be used. Head hair specifically means scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The process of laboratory analysis of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the initial stage of processing a sample into a lab's system. This includes ensuring the sample was correctly sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and completing additional data entry if absent from an electronic chain of custody system.

Screening is a preliminary assessment for drugs of abuse. While Screening efficiently excludes drug use for most samples, a positive finding needs verification for legal acceptance. Samples that test presumptively positive in Screening need further confirmation.

Should a sample show presumptive positives during Screening, more hair is retrieved from the initial sample for Extraction. In Extraction, drugs are retrieved from hair at lower concentrations than in other methods (like urine or oral fluid), thus making hair drug testing the most challenging methodology.

Confirmation of positive screening results is done using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation when necessary. The complete laboratory workflow from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can identify drug use for up to 90 days, unlike urine tests with a shorter detection duration.
• Resilience against tampering: Cheating a hair drug test is significantly challenging, enhancing the reliability of results.
• Historical data provision: It can reveal a pattern of drug usage over time, rather than just recent consumption.

Limitations:

• Lacks recent usage detection: Around 5-7 days are required for drugs to appear in hair after use.
• Expense: Hair drug testing tends to be costlier than other drug testing techniques.
• Inconsistent results: Variables like hair color and individual differences in hair growth can influence drug metabolite concentration in hair.

Note: Although commonly termed as "hair follicle tests," the examination itself focuses on the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Caledonia, WI, the benefits of hair follicle testing over urine tests are numerous. Hair tests offer an extended detection period, making them more effective in uncovering long-term drug use. While urine tests detect recent substance use, hair follicle tests provide a broader snapshot and are nearly tamper-proof. This ensures reliable data that's harder to manipulate.

For employers, hair follicle testing is superior due to its inability to be easily cheated. Unlike urine tests, hair samples cannot be substituted or easily contaminated. This leads to assured accuracy and greater compliance with workplace policies, enhancing safety and trust within the organization.

Extended Detection Window

Hair follicle testing in Caledonia, WI, offers an extended detection window, capable of identifying drug use over the past 90 days. This extended timeframe provides a deeper insight into an individual’s substance history, proving invaluable to employers. Unlike urine tests, which typically detect recent use, hair follicle tests highlight long-term patterns.

Employers benefit from the comprehensive view offered by hair testing. With the ability to detect drug use over a prolonged period, it offers a more complete assessment of an applicant or employee’s habits. This advantage is particularly useful for enforcing strict zero-tolerance policies.

Tamper-Resistant Testing Method

In Caledonia, WI, the tamper-resistant nature of hair follicle tests provides peace of mind for accurate drug testing. Unlike other tests, hair samples are difficult to adulterate, reducing the risk of manipulation. This significantly enhances the reliability of test results, supporting confident decision-making in sensitive situations.
