Hair Follicle Drug Testing - Green, OR

What it is, How it works

Hair analysis is increasingly recognized as an effective method for identifying drug and alcohol consumption. By capturing biomarkers within the fibers of the developing hair strand, hair offers a prolonged history of substance use. When collected from near the scalp, it can reveal up to around a 3-month period of alcohol and drug usage. Hair collection is straightforward, somewhat resistant to tampering, and convenient for transport.

A 1.5-inch segment of roughly 200 hair strands (comparable to the thickness of a #2 pencil) near the scalp yields 100mg of hair, which is the optimal amount for initial testing and verification. For EtG, additional analysis, and/or evaluations exceeding 10 panels, 150mg of the sample is advisable. It's best to measure the sample with a jeweler’s scale. In the absence of scalp hair, an equivalent volume of body hair can be used. When mentioning head hair, we mean only scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The four key phases in processing a drug test in the lab are Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the beginning of processing a sample into the lab’s system. It involves ensuring the sample was sealed and sent correctly, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data needed beyond what an electronic chain of custody system provides.

Screening is a preliminary assessment for substances. While it is a cost-effective method to eliminate drug usage in most specimens, a positive result requires confirmation for legal standing. Samples that are tentatively positive in Screening need further confirmation.

If Screening suggests a positive result, more hair is taken from the initial sample and readied for Extraction. At this stage, substances are isolated from the hair at much lower concentrations compared to other methods (e.g., urine or oral fluid), which explains why hair drug analysis is the most challenging method to conduct.

Confirmation of any positive Screening outcome is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples suggesting positive results are cleansed before confirmation as necessary. The complete lab process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 standard accreditation.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a limited detection range.
• Hard to manipulate: Altering a hair drug test is highly challenging, which enhances the result's accuracy.
• Offers usage trends: Provides insights on drug usage over time, not just recent consumption.

Limitations:

• Incapable of recent detection: Drugs need roughly 5-7 days before they are traceable in hair.
• Expense: Hair drug tests tend to be costlier compared to other drug testing techniques.
• Result variability: Elements like hair shade and individual hair growth variations may influence drug metabolite levels in hair.

Note: Commonly called "hair follicle tests", the procedure actually examines the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Green, OR, the benefits of hair testing become evident when contrasted with traditional urine tests. Hair follicle tests provide an extended detection period, uncovering drug use up to 90 days back, while urine tests typically cover a much shorter window. This expanded timeframe offers a more comprehensive picture of test subjects' substance use history.

Hair testing's reliability outmatches that of urine tests. Since hair samples are gathered under direct observation, opportunities for cheating are minimized. Urine tests, however, can be tampered with more easily, calling their reliability into question.

Extended Detection Window

One of the standout features of hair follicle testing in Green, OR, is its extended detection window. This method can trace drug use up to 90 days back, offering employers a thorough perspective on substance use patterns over time. Such insights are critical for informed decision-making.
