Hair Follicle Drug Testing - Ravenna, TX

What it is, How it works

Hair testing is recognized as a key method for identifying drug and alcohol consumption. Hair retains a prolonged record of alcohol and drug interactions by embedding biomarkers in the hair strand's fibers as it grows. When specimens are cut close to the scalp, hair testing offers a detection period of up to approximately three months for alcohol and drugs. Collecting hair is straightforward, not easily tampered with, and convenient to transport.

A 1.5-inch segment involving around 200 strands of hair (similar in size to a #2 pencil) near the scalp yields 100mg, which is the ideal sample for both screening and confirmation. For EtG, additional tests, or panels surpassing 10, a specimen of 150mg is preferable. It is advised to weigh the sample using a jeweler’s scale. In cases where scalp hair is absent, a comparable quantity of body hair may be used. "Head hair" specifically refers to scalp hair, whereas "body hair" pertains to all other hair types (facial, axillary, etc.).

Process Overview

The laboratory process for drug test outcomes comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is about the initial integration of a sample into a lab’s system. It involves ensuring the sample is sealed and shipped correctly, assigning a random LAN (Laboratory Accessioning Number), and finishing any extra data entry absent in an electronic chain of custody system.

Screening is an initial rapid test for drugs of abuse. Although it is cost-efficient for ruling out drug use in most samples, a positive result requires confirmation to be legally admissible. Samples that test positive in Screening need a follow-up confirmation.

For samples testing positive initially, additional hair is obtained from the original sample for the Extraction phase. Here, drugs are extracted from hair at a much lesser concentration compared to other methods (e.g., urine or oral fluid), which is why hair drug testing is the most challenging method to execute.

Positive screening outcomes require Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. All samples testing presumptive positive are cleansed before confirmation if necessary. The overall lab process—from Accessioning to Confirmation—is evaluated according to both CAP (College of American Pathologists) Hair standards and ISO/IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage for up to 90 days, unlike urine tests, which have a shorter detection span.
• Deterring fraud: It is exceedingly difficult to manipulate a hair drug test, enhancing accuracy.
• Showcases a historical usage pattern: It outlines a drug usage pattern over time, rather than only recent use.

Limitations:

• Inability to identify recent use: Drugs become detectable in hair approximately 5-7 days after use.
• Expense: Hair drug tests tend to be pricier than other drug testing methods.
• Result variability: Factors like hair color and individual hair growth differences can influence drug metabolite levels in hair.

Note: Though commonly called "hair follicle tests," the test actually examines the hair strand, not the hair follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

When comparing hair follicle testing with traditional urine tests in Ravenna, TX, the advantages are clear. Hair tests deliver enhanced detection accuracy and are more effective in uncovering drug usage over an extended timeline. While urine tests are limited to recent substance use, hair testing provides a fuller picture of a person's history.

Employers in Ravenna benefit greatly from the reliability of hair tests, which reduce the chance of false negatives and increase the accuracy of detecting long-term drug use. This makes hair testing the preferred choice for maintaining workplace safety and policy compliance.

Extended Detection Window

The long detection window of hair follicle testing stands out as a key advantage in Ravenna, TX. Unlike urine tests, which only indicate recent drug use, hair analysis can reveal substance intake up to 90 days prior, offering a more comprehensive view of a person’s habits.

This extended detection timeframe is particularly useful for employers seeking to understand an applicant or employee's long-term substance behavior. By choosing hair follicle testing, companies gain invaluable insight into potential hires or current staff members.

Tamper-Resistant Testing Method

Hair follicle tests in Ravenna, TX, provide significant protection against sample adulteration. The unique collection method makes it nearly impossible to tamper with results, ensuring test integrity and reliability.

This robustness makes hair testing a preferred choice for organizations looking to mitigate risks associated with dishonest practices. The certainty that results are accurate and unquestionable is invaluable for maintaining a fair and drug-free work environment.
