Hair Follicle Drug Testing - Forest Hill, LA

What it is, How it works

Hair screening has emerged as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and various substances by incorporating biomarkers in the hair strand's fibers as it grows. When acquired near the scalp, it can reveal up to about a 90-day period of detection for alcohol and drugs. Hair collection is straightforward, relatively resistant to tampering, and easy to transport.

A segment of 1.5 inches with roughly 200 strands (approximately the width of a #2 pencil) nearest to the scalp offers 100mg of hair, which is optimal for both screening and confirmation. For tests like EtG, additional analyses, or those exceeding 10 panels, 150mg is advised. It's suggested to measure the sample using a jeweler’s scale. Should scalp hair be inaccessible, an equivalent quantity of body hair can be collected. The term head hair pertains solely to scalp hair, while body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The key steps in laboratory drug test result processing include Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample undergoes initial processing into a lab's system, which includes verifying that the sample was correctly sealed and shipped, assigning it a LAN (Laboratory Accessioning Number), and accommodating any further data entry absent in an electronic chain of custody system.

Screening offers a preliminary rapid assessment for substances. Though it is cost-efficient for excluding drug use in most samples, a positive screen must be validated for courtroom admissibility. Any samples that appear positive during Screening require an additional confirmation.

If a sample appears positive at the Screening stage, more hair is extracted from the initial sample for the Extraction process. This step involves extracting drugs from hair at a much lower concentration than other methods (e.g., urine or oral fluid), making hair drug screening one of the most complex methodologies to execute.

A GC/MS, GC/MS/MS, or LC/MS/MS is used for confirming any positive screening outcomes. Presumed positive samples undergo washing prior to confirmation as needed. The process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Prolonged detection period: Hair drug tests can trace drug use for up to 90 days, unlike urine tests with a shorter detection timeline.
• Challenging to falsify: Hair drug tests are difficult to deceive, enhancing result accuracy.
• Supplies historical usage data: It reflects a timeline of drug use over a duration, rather than just recent use.

Limitations:

• Incapable of identifying recent use: Detection in hair requires roughly 5-7 days post-consumption.
• Expense: Generally, hair drug tests are pricier than alternative drug testing approaches.
• Result variations: Aspects like hair color and individual variances in hair growth can influence drug metabolite concentration in hair.

Note: Although often termed "hair follicle tests," this test evaluates the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why Hair Follicle Testing Beats Urine Testing in Forest Hill, LA
Hair follicle drug tests offer a distinct advantage over traditional urine tests through superior detection accuracy and long-term reliability. The extended detection period, covering up to 90 days, gives a more comprehensive picture of past substance use.

Urine tests, while effective for recent consumption, cannot match the breadth of historical data provided by hair tests. Employers value hair testing for its robust detection and inability to be easily circumvented, leading to a more dependable evaluation.

Extended Detection Window
