Hair Follicle Drug Testing - Bentley, LA

What it is, How it works

Hair testing has gained recognition as an effective means for identifying alcohol and drug consumption. Hair retains a long-term record of drugs and alcohol by encapsulating biomarkers within the fibers of the growing strand. When obtained near the scalp, hair can offer a detection period of up to around three months for drugs and alcohol. Hair collection is straightforward, relatively resistant to tampering, and simple to transport.

A 1.5-inch hair sample of approximately 200 strands (roughly the size of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal quantity for screening and confirmation. For EtG, supplementary tests, and/or panels exceeding 10, a 150mg sample is advised. It is recommended to weigh the sample using a jeweler's scale. If scalp hair isn't available, a similar quantity of body hair can be collected. "Head hair" specifically refers to scalp hair. "Body hair" encompasses all other types (such as facial or axillary hair).

Process Overview

The lab processing of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into a lab system. This process ensures the sample was sealed and shipped correctly, a random LAN (Laboratory Accessioning Number) is assigned, and any extra data entry not captured by an electronic chain of custody system is completed.

Screening conducts an initial rapid assessment for drug misuse. Although Screening is a cost-efficient method to exclude drug usage in most samples, a positive result must be confirmed to be valid in court. Any samples that screen positive tentatively necessitate a secondary confirmation.

If Screening yields a presumptive positive, additional hair is extracted from the original sample for the Extraction phase. Here, drugs are drawn out at significantly lower concentrations than in other testing methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to execute.

Confirmation of any positive screening is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicated as presumptive positives undergo washing before confirmation as deemed necessary. The entire lab process, from Accessioning to Confirmation, is examined under both the CAP Hair designation and in compliance with ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for as far back as 90 days, unlike urine tests which have a narrower detection timeframe.
• Challenging to falsify: Cheating a hair drug test is very difficult, thus enhancing result accuracy.
• Offers historical insight: It can display a pattern of drug consumption over time, beyond recent use alone.

Limitations:

• Inability to detect recent usage: Drugs require about 5-7 days to become detectable in hair.
• Expense: Hair drug tests tend to cost more compared to other drug testing techniques.
• Result variability: Hair color and individual growth variations can influence the concentration of drug metabolites present in the hair.

Note: Although frequently termed "hair follicle tests", the analysis is conducted on the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why is hair testing preferred over urine tests in Bentley, LA? Superior detection accuracy and reliability are key factors. Hair tests provide a more extensive overview of substance history, unlike urine tests which only indicate recent usage.

Employers benefit by choosing hair testing as they gain a thorough understanding of an individual's substance habits. The longer detection period enables an informed decision-making process compared to urine tests, which have a limited detection timeframe.

Hair tests are difficult to cheat, thus providing more reliable results.

Extended Detection Window

One notable advantage of hair follicle testing in Bentley, LA, is the extended detection window it offers, covering up to 90 days. This expansive timeframe gives potential employers a comprehensive overview of an individual’s substance history.

This benefits organizations in identifying persistent usage patterns which might not be evident with shorter-term tests. Employers access crucial insights reflecting long-term drug habits, promoting safer workplace environments.

An extended detection period aids in understanding an applicant’s history beyond mere superficial evaluation, ensuring a deeper insight into substance use.
