Hair Follicle Drug Testing - Goehner, NE

What it is, How it works

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol use. Hair captures a chronological history of alcohol and drug intake by embedding biomarkers in the fibers of growing hair. When taken from near the scalp, hair can offer up to a three-month window for detecting alcohol and drugs. Hair sampling is straightforward to collect, somewhat resistant to tampering, and simple to transport.

A 1.5-inch sample of approximately 200 hair strands (roughly the diameter of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the preferred quantity for both screening and confirmation. For EtG, additional tests, or tests exceeding 10 panels, a specimen of 150mg is advisable. It is suggested to measure the hair specimen using a jeweler’s scale. If scalp hair is not available, a comparable amount of body hair may be used. "Head hair" refers specifically to scalp hair, whereas "body hair" encompasses other types such as facial or axillary hair.

Process Overview

The laboratory processes of a drug test result can be distilled into four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary handling of a specimen within the lab's system. This stage involves confirming that the sample is correctly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and filling out any supplementary data entries not captured by an electronic chain of custody.

Screening constitutes a preliminary examination to check for drugs of abuse. Although Screening is a budget-friendly method to dismiss drug use in most samples, a positive result from this stage must be validated to be legally defensible. Samples that screen positive require further confirmation.

When a sample shows presumptive positivity at the Screening phase, additional hair is extracted from the initial specimen for the Extraction phase. This phase involves isolating drugs from hair at notably lower concentrations than other methods like urine or oral fluid screening, making hair drug screening particularly challenging to conduct.

Validation of any positive findings from Screening is accomplished via GC/MS, GC/MS/MS, or LC/MS/MS procedures. All presumptively positive samples undergo pre-confirmation washing as necessary. The entire lab protocol, from Accessioning to Confirmation, is meticulously reviewed under both the CAP (College of American Pathologists) Hair designation and the accreditation standards of ISO / IEC 17025.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, whereas urine tests have a much shorter detection period.
• Difficult to falsify: The results of hair drug tests are more reliable due to the challenge in tampering with the test.
• Reveals historical usage: It offers insights into the pattern of drug use over time, rather than simply recent use.

Limitations:

• Inability to detect recent usage: Drugs become detectable in hair roughly 5-7 days after use.
• Expense: Hair drug tests generally entail higher costs than other testing methods.
• Variability in results: Aspects like hair color and personal differences in hair growth can influence drug metabolite concentrations in hair.

Please note: Although often labeled as “hair follicle tests,” the actual test examines the hair shaft, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Goehner, NE, hair follicle tests are increasingly viewed as superior to traditional urine tests. Offering up to 90 days of detection, hair tests provide employers with a clear view of a potential or current employee's substance history.
