Hair Follicle Drug Testing - Weeks, LA

What it is, How it works

Hair analysis has emerged as a robust method for identifying drug and alcohol consumption. Hair strands provide a detailed history of substance use by capturing markers within the hair fibers as they grow. When the sample is taken close to the scalp, it can reveal drug and alcohol use for a period of up to 3 months. Hair collection is straightforward, tough to tamper with, and easy to transport.

A 1.5-inch section comprising roughly 200 hair strands (similar in size to a #2 pencil) nearest to the scalp will result in 100mg of hair, which is the optimal sample size for both screening and confirmation. For EtG, add-ons, or panels exceeding ten, it is suggested to use 150mg of the sample. We advocate for weighing the sample using a jeweler’s scale. Should scalp hair not be available, an equivalent quantity of body hair can be used. When distinguishing head hair, we mean scalp hair specifically. Body hair encompasses all other types (such as facial, axillary, etc.).

Process Summary

The core steps in processing a drug test result in the lab are Accessioning, Screening, Extraction, and Confirmation.

Accessioning consists of the initial intake of a sample into the lab's database. Activities include verifying that the sample was sealed and delivered correctly, assigning a unique LAN (Laboratory Accessioning Number), and completing any missing entries not offered by an electronic chain of custody system.

Screening is a preliminary cursory examination for drug abuse. Screening is budget-friendly and can rule out drug use in most samples; however, to be admissible in court, a positive screen requires confirmation. Samples with presumptive positives in Screening demand a follow-up confirmation.

For samples with presumptive positives during Screening, additional hair from the original sample is prepared for Extraction. During Extraction, the concentration of drugs extracted from hair is lower than with other methods (like urine or oral fluid), which makes hair drug testing particularly challenging.

Confirmatory tests for any positive screening are conducted using GC/MS, GC/MS/MS, or LC/MS/MS. Samples with presumptive positives are washed as necessary before confirmation. The complete lab process, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair designation, alongside adherence to ISO / IEC 17025 standards.

Benefits of Hair Drug Testing:

• Extended detection span: Hair drug tests can reveal drug usage for as long as 90 days, unlike urine tests that have a narrow detection window.
• Difficult to manipulate: Cheating on a hair drug test is challenging, making the results more reliable.
• Offers past usage data: Provides a record of drug use over time, rather than just recent consumption.

Drawbacks:

• Cannot detect very recent use: It takes about 5-7 days for drugs to be detectable in hair.
• Expense: Hair drug tests are often pricier compared to other drug testing techniques.
• Result variability: Factors like hair color and personal differences in hair growth may impact the concentration of drug metabolites in 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

The advantages of hair testing over urine tests in Weeks, LA, are evident. Hair follicle tests boast superior detection capabilities with their extended window of up to 90 days, unlike urine tests limited to recent usage. This makes them a preferred choice for organizations aiming for comprehensive accuracy in substance detection.

Reliability is another hallmark of hair testing. As opposed to the short detection span of traditional urine tests, hair analysis offers a broader view of an individual's substance history. This translates to peace of mind and enhances trust in the testing process. Moreover, hair tests significantly reduce the chances of manipulation, offering uncheatable results.

Extended Detection Window

In Weeks, LA, hair follicle tests are renowned for their extensive detection period, providing a robust 90-day overview of drug use. This extended window offers employers invaluable insights into an individual's longer-term substance patterns.
