Hair Follicle Drug Testing - Forest Glen, MD

What it is, How it works

Hair testing is recognized as an effective method for detecting drug and alcohol usage. Hair offers an extended history of drugs and alcohol by trapping biomarkers within the hair fibers as they grow. When collected near the scalp, hair can provide a detection window of up to roughly 3 months for substances. Hair is easy to collect, relatively challenging to adulterate, and simple to ship.

A sample of 1.5 inches, consisting of around 200 hair strands (approximately the width of a #2 pencil) nearest the scalp, will yield 100mg of hair, which is the optimal sample size for screening and confirmation. For EtG, add-ons, and/or analyses exceeding 10 panels, 150mg of the sample is advised. It's recommended to weigh the sample with a jeweler’s scale. If scalp hair isn't available, an equivalent amount of body hair can be used. When discussing head hair, we specifically mean scalp hair, while body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

There are four key stages in the laboratory processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial processing of a specimen into a lab’s system. This includes checking that the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any further data entry not included by an electronic chain of custody system.

Screening conducts a quick preliminary examination for drugs of abuse. While Screening is an economical method to rule out drug use for most samples, a positive screen must be verified to be valid in court. Samples that are presumptively positive in Screening require further confirmation.

If a sample is presumptively positive in Screening, additional hair is extracted from the initial sample and processed for Extraction. In this step, drugs are extracted from hair at a lower concentration than other methods (e.g., urine or oral fluid), which is why hair drug screening is the most challenging methodology to perform.

Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleaned before confirmation as needed. The complete laboratory process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for up to 90 days, compared to urine tests which have a shorter detection window.
• Hard to falsify: It is very challenging to falsify a hair drug test, making the results more reliable.
• Offers historical data: It can highlight a pattern of drug use over time, not just recent consumption.

Limitations:

• Inability to detect recent use: It takes about 5-7 days for drugs to show up in hair.
• Price: Hair drug tests are typically more costly than other drug testing methods.
• Variability in results: Factors such as hair color and individual differences in hair growth can influence the concentration of drug metabolites in the hair.

Note: While often called "hair follicle tests", the examination actually analyzes the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Forest Glen, MD, hair follicle testing surpasses urine tests in detecting drugs due to its extensive detection window. Hair testing provides a more reliable and accurate snapshot of an individual's substance use history compared to urine tests, which mostly reveal recent drug use.
Hair follicle tests prove invaluable by highlighting patterns of usage over an extended timeframe.

The ability of hair tests to detect drug presence for up to 90 days offers a superior view of an individual's commitment to a drug-free lifestyle. In contrast, urine tests have a limited detection span.

Extended Detection Window

For employers in Forest Glen, MD, hair follicle testing offers an extended detection window for drug use. Capable of revealing substances used up to 90 days prior, this method provides a more comprehensive overview of an individual's substance history.
This allows employers to make more informed decisions based on long-term patterns rather than short-term habits.

The extended window of hair follicle tests surpasses the typical week-long scope of urine tests, revealing sustained non-compliance with drug-free policies. This is crucial in assessing candidates thoroughly.
