Hair Follicle Drug Testing - Hawley, TX

What it is, How it works

Hair testing is increasingly recognized as an effective method for detecting drug and alcohol use. Hair offers a comprehensive history of substance exposure by embedding biomarkers within the fibers of the growing hair. When obtained near the scalp, hair can reveal a detection window of up to roughly three months for substances like alcohol and drugs. Hair sampling is straightforward, relatively challenging to tamper with, and convenient to transport.

A sample of 1.5 inches, consisting of approximately 200 hair strands (about the thickness of a #2 pencil) closest to the scalp, yields about 100mg of hair, which is the optimal amount for both screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a sample of 150mg is suggested. We advise using a jeweler’s scale to weigh the specimen. If scalp hair isn't accessible, a similar quantity of body hair can be collected. References to head hair specifically mean scalp hair, while body hair encompasses all other types (e.g., facial, axillary).

Process Overview

The primary stages of lab processing in a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to initially processing a specimen into a laboratory’s system. This step involves checking that the specimen is correctly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing required data entry not captured by an electronic chain of custody system.

Screening involves performing a preliminary test for potential drug abuse indicators. While Screening is a cost-efficient method to exclude drug use in most samples, a positive result needs to be verified for legal admissibility. Presumptively positive samples in Screening need further confirmation.

If a screening result is likely positive, additional hair is taken from the original sample and prepared for Extraction. In Extraction, drugs are retrieved from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), making hair drug screening among the most complex methodologies.

Confirmation of any positive screening outcome is carried out via GC/MS, GC/MS/MS, or LC/MS/MS. All samples that initially appear positive are washed before confirmation if necessary. The entire lab procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair tests detect drug use for as long as 90 days, whereas urine tests have a much shorter detection span.
• Hard to manipulate: It's extremely challenging to falsify a hair drug test, ensuring more reliable results.
• Historical insights: It provides a record of drug use over time, rather than just recent activity.

Limitations:

• Inability to detect immediate use: It requires about 5-7 days post-exposure for drugs to register in hair.
• Price: Hair drug tests generally cost more than other testing methods.
• Result variability: Factors such as hair color and personal hair growth variations may impact metabolite concentration in hair.

Note: Though commonly termed "hair follicle tests," the analysis focuses on the hair strand itself, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

When it comes to drug testing in Hawley, TX, hair follicle testing offers distinct advantages over urine tests. While traditional urine tests remain common, hair testing provides enhanced detection accuracy and reliability, making it a superior choice.

Hair testing can reveal substance use up to 90 days back, challenging the limited timeframe of urine tests. This extended detection period allows a more comprehensive view of an individual's substance history, crucial for informed decisions.
