Hair Follicle Drug Testing - Tira, TX

What it is, How it works

Hair analysis has emerged as an effective means for identifying drug and alcohol consumption. Hair acts as a long-lasting record of alcohol and drug use by embedding biomarkers within the strands as they grow. When gathered near the scalp, hair can offer a detection period of roughly 3 months for alcohol and drugs. Hair is straightforward to gather, somewhat resistant to tampering, and convenient to transport.

A 1.5-inch sampling of roughly 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal amount for both screening and confirmation. For EtG, additional testing, and/or panels exceeding ten, a specimen of 150mg is advised. Using a jeweler's scale is recommended for weighing the specimen. If scalp hair isn't obtainable, an equivalent quantity of body hair can be used. References to head hair pertain specifically to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The four primary stages in laboratory processing for drug test outcomes are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the preliminary incorporation of a sample into the laboratory's system. This process comprises verifying the sample's seal and shipping integrity, allocating a random LAN (Laboratory Accessioning Number), and completing any additional data input not present in an electronic chain of custody system.

Screening provides an initial rapid assessment for the presence of drugs. While Screening offers an economical method to negate drug use in most samples, positive findings require further corroboration to be acceptable in a legal setting. Any samples with tentative positive results from Screening necessitate additional confirmation.

If there is a tentative positive result in the Screening phase, more hair is taken from the initial sample and set for Extraction. During this phase, drugs are extracted from hair at significantly lower concentrations than in other techniques (such as urine or oral fluids), establishing hair drug screening as the most challenging procedure to execute.

Confirmation of any screening positive result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with tentative positive results are cleansed before confirmation if necessary. The entire laboratory procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Prolonged detection window: Hair drug tests can identify drug use for up to 90 days, whereas urine tests offer a shorter detection period.
• Challenging to manipulate: It is notably challenging to manipulate a hair drug test, resulting in more reliable outcomes.
• Offers historical insights: It provides a record of drug usage over a duration, not merely recent use.

Limitations:

• Inability to detect immediate use: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair drug tests are typically pricier than other forms of drug testing.
• Result variability: Aspects like hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: Though often termed "hair follicle tests", the test evaluates the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing is superior to urine tests in Tira, TX, offering unmatched detection accuracy and reliability. This is particularly essential in environments where strict compliance is necessary, such as workplaces with zero-tolerance policies. The hair test provides a longer detection window, revealing substance use that might pass unnoticed in urine tests.
