Hair Follicle Drug Testing - Kraemer, LA

What it is, How it works

Hair testing is now recognized as a significant means for uncovering drug and alcohol usage. Hair strands encapsulate biomarkers in their fibers, offering an extended history of alcohol and drug exposure. When obtained near the scalp, hair can reveal drug or alcohol use within roughly a 3-month period. The collection of hair is straightforward, challenging to tamper with, and convenient to transport.

A sample measuring 1.5 inches and consisting of around 200 hair strands (approximately the width of a #2 pencil) closest to the scalp can yield 100mg of hair, the perfect quantity for analysis and confirmation. For EtG, add-ons, or tests exceeding 10 panels, it is advisable to use 150mg of the sample. We suggest using a jeweler's scale to weigh the specimen. In the event that scalp hair is unavailable, an equivalent amount of body hair is acceptable. "Head hair" specifically refers to scalp hair, while "body hair" encompasses all other hair categories (facial, axillary, etc.).

Process Overview

The four primary procedures in processing a drug test outcome in a lab setting are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves introducing the sample into the laboratory's system efficiently. This process verifies that the sample is correctly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and completes additional data entry not captured by an electronic chain of custody system.

Screening serves as a preliminary check for substance misuse. It is a cost-effective measure to dismiss drug usage on most samples, but a confirmed screen is necessary for court acceptability. Any samples showing presumptive positivity in Screening require further confirmation.

Upon a presumptive positive outcome in Screening, more hair is extracted from the original sample for the Extraction process. This stage involves isolating drugs from hair at concentrations slightly lower than other methods (e.g., urine or oral fluid), hence making hair drug screening the most intricate methodology to execute.

Confirming a positive screening result is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All samples registering a presumptive positive are carefully cleansed before the confirmation as deemed appropriate. The entire lab procedure, from Accessioning to Confirmation, undergoes evaluation according to both the CAP (College of American Pathologists) Hair criteria and ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection range: Hair drug tests can recognize drug usage extending to 90 days, unlike urine tests with shorter detection periods.
• Reduced likelihood of evasion: Evading a hair drug test is exceptionally challenging, ensuring more reliable outcomes.
• Provides historical insight: It enables identifying a drug usage pattern over time rather than merely recent use.

Limitations:

• Inability to identify recent use: Drugs require 5-7 days to become traceable in hair.
• Expense: Hair drug testing is generally pricier than other methods.
• Result variability: Factors like hair color and individual hair growth variations may influence drug metabolite levels in hair.

Note: Commonly called "hair follicle tests", the test actually evaluates the strand rather than the follicle under the scalp

Why Hair Follicle Testing Beats Urine Testing

When it comes to drug detection, hair follicle testing offers notable advantages over urine tests in Kraemer, LA. The superior accuracy of hair tests means that detecting drugs is not only more reliable but also less prone to errors. Unlike urine tests, hair analysis offers broader security against test manipulation, making it a preferred choice for many.
Traditional urine tests, while useful, cannot offer the same extended detection period.

Extended Detection Window

Hair follicle testing provides a significant detection window of up to 90 days, a feature that surpasses the limitations of urine tests. This extended timeframe assists employers in Kraemer, LA, offering a thorough insight into an individual's long-term substance use history. For those in roles of hiring or managing personnel, this data is invaluable for informed decision-making.
Urine tests tend to focus more on recent use, missing long-term patterns.

Tamper-Resistant Testing Method

In Kraemer, LA, ensuring the integrity of drug testing is critical, and hair follicle testing excels in this regard. The method significantly reduces sample tampering possibilities, providing employers confidence in the results. Unlike urine samples, hair samples are harder to adulterate, ensuring a true reflection of a user’s drug history.
This aspect not only promotes trust but also enhances the efficiency of testing processes.
