Hair Follicle Drug Testing - Stonewall, LA

What it is, How it works

Hair testing is recognized as an essential method for identifying drug and alcohol consumption. Hair effectively chronicles a prolonged history of substance use by embedding biomarkers within the strands of the hair as it grows. Collecting samples near the scalp can offer up to around a 3-month window of detection for alcohol and drugs. The collection of hair is straightforward, less prone to tampering, and easy to transport.

A sample of 1.5 inches from roughly 200 strands of hair (about the thickness of a #2 pencil) nearest the scalp equates to 100mg, which is the preferred amount for screening and confirmation. For tests including EtG, add-ons, and/or panels beyond 10, a sample weighing 150mg is advisable. Using a jeweler’s scale to measure the sample is suggested. In cases where scalp hair isn't available, an equivalent quantity of body hair can be used. When discussing head hair, it specifically means scalp hair. Body hair includes all other types (facial, axillary, etc.).

Process Overview

There are four core phases in the laboratory handling of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning consists of the initial incorporation of a sample into a laboratory's workflow. This step verifies the proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes additional data entry not covered by an electronic chain of custody system.

Screening is an initial swift assessment for substances of abuse. Although Screening is an economical approach to exclude drug use in most samples, a positive result must be confirmed to be legally admissible. Presumptive positive samples from the Screening phase must undergo a secondary confirmation.

For samples presumptively positive in Screening, more hair is extracted from the initial sample to prepare for Extraction. Here, drugs are isolated from hair at much lower concentrations compared to other methods (e.g., urine or oral fluid), which makes hair drug testing the most challenging method to execute.

Confirmation of any positive screening result is completed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples that test positive are washed prior to confirmation as necessary. The full laboratory procedure from Accessioning to Confirmation is conducted 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, unlike urine tests, which have a shorter window.
• Tamper-resistant: It is extremely hard to manipulate a hair drug test, ensuring more reliable results.
• Offers historical insights: It provides a longitudinal view of drug use, rather than just recent use.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair approximately 5-7 days after consumption.
• Expense: Hair drug testing tends to be costlier than other drug test methods.
• Result variability: Factors like hair color and individual differences in hair growth can influence the drug metabolite concentration within the hair.

Note: Though commonly called "hair follicle tests", the analysis is performed on the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Stonewall, LA, the benefits of hair follicle testing overshadow traditional urine tests. Hair tests provide a longer detection window, allowing for a thorough understanding of an individual's drug history. This long-term view is crucial for employers aiming to maintain a safe, drug-free workplace, as it reveals substance use over the past 90 days.

Beyond the detection window, the hair test's reliability in resisting tampering makes it a preferred option. While urine tests can only capture recent drug use, hair tests offer extensive insight into an individual's habits, presenting a more comprehensive picture of personal accountability and adherence to company policies.

Extended Detection Window

In Stonewall, LA, the extended detection window offered by hair follicle testing is a breakthrough in understanding substance use patterns. Unlike other methods, hair tests can uncover drug use over a period of up to 90 days, providing a panoramic view of an individual's history. This is particularly useful for employers looking to get a complete picture of an applicant or current employee's drug habits.

Utilizing the length of the hair growth cycle, these tests detect even infrequent substance use, which is often missed by shorter-term testing methods like urine analysis. This long-term insight is invaluable for upholding safety and compliance standards in various settings, from workplaces to legal proceedings.
