Hair Follicle Drug Testing - Valdese, NC

What it is, How it works

Hair testing is now recognized as an effective method for identifying drug and alcohol consumption. It offers a prolonged history, capturing biomarkers within the strands of growing hair. Hair collected from near the scalp can indicate alcohol and drug use for a period of up to three months. The process of collecting hair is straightforward, it is relatively resistant to tampering, and it can be transported with ease.

A 1.5-inch sample consisting of roughly 200 hair strands, equivalent to a #2 pencil in size, taken closest to the scalp provides 100mg of hair, which is ideal for both screening and confirmation. For EtG, add-ons, or tests exceeding ten panels, it is advisable to use 150mg of the sample. Measuring the sample on a jeweler’s scale is recommended. When scalp hair is not available, an equal quantity of body hair may be collected. The term head hair refers exclusively to scalp hair, whereas body hair denotes all other types, including facial and axillary hair.

Process Overview

The laboratory processing of a drug test result involves four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning covers the initial integration of a sample into a lab’s system. This step involves confirming the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not covered by an automated chain of custody system.

Screening consists of a preliminary assessment for the presence of drugs of abuse. Although Screening efficiently eliminates drug usage in most samples, a positive screen must be confirmed for court admissibility. Samples showing presumed positivity in Screening necessitate further confirmation.

In the event of a presumptive positive in Screening, additional hair is drawn from the original sample for Extraction. During this phase, drugs are extracted from hair at concentrations much lower than those in other methods (e.g., urine or oral fluid), making hair drug screening notably challenging to conduct.

Confirmation of positive screening results is performed using GC/MS, GC/MS/MS or LC/MS/MS. Prior to confirmation, presumptive positive samples are washed as necessary. The entire lab process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection period: Hair drug tests can reveal drug use for as long as 90 days, while urine tests offer a significantly shorter time frame.
• Difficulty to manipulate: Cheating a hair drug test is particularly challenging, thus increasing result accuracy.
• Reports historical usage: Hair testing can illustrate a pattern of drug use over time, unlike tests that only indicate recent usage.

Limitations:

• Inability to detect recent consumption: Drugs typically become detectable in hair approximately 5-7 days post-use.
• Expense: Hair drug testing tends to be more costly than alternative drug testing techniques.
• Variability in results: Drug metabolite concentration in hair can be influenced by hair color and individual differences in hair growth.

Note: Commonly known as "hair follicle tests", this test analyzes the hair strand and not the follicle under the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing offers better detection capabilities than urine tests, making it a preferred option in Valdese, NC. Unlike urine tests, which usually detect usage for up to a week, hair tests can trace drug consumption over several months. This increased reliability helps employers maintain stringent safety standards.

The detection reliability of hair tests makes them more suitable for organizations aiming to enforce zero-tolerance policies. With a much broader detection window than urine tests, employers gain a more comprehensive view of an individual's substance history, thus better safeguarding workplace environments.

Extended Detection Window

In Valdese, NC, one key advantage of hair follicle testing is its extended detection window of up to 90 days. This long-term insight enables employers to effectively monitor an individual's substance use, distinguishing it from other methods with much shorter detection spans.

This comprehensive view assists employers in better assessing potential hires or current employees, thereby ensuring a safer workplace. The ability to detect prolonged drug use with hair tests stands as a vital tool for reviewing an individual's consistent adherence to drug-free policies.

Tamper-Resistant Testing Method
