Hair drug testing, or hair follicle drug testing, is a scientific approach to identifying drug use through the examination of hair specimens.

How it works:

• Drug enters bloodstream: Once drugs are used, the substances and their metabolites enter into the bloodstream.
• Drugs reach hair follicles: Due to the blood vessel in each hair follicle, drugs travel from the bloodstream into the hair follicle.
• Drugs get trapped in hair: While the hair extends, the trace chemical compounds become embedded in the hair strand's cortex.
• Hair sample collection: Hair is sampled, usually from the scalp (or body hair if insufficient head hair is available).
• Lab analysis: The collected hair sample undergoes laboratory testing.
  • Screening: An initial Enzyme-Linked Immunosorbent Assay (ELISA) is performed to detect drug metabolites.
  • Confirmation: When the ELISA test is positive, a more thorough confirmation test, like Gas Chromatography-Mass Spectrometry (GC/MS) or Liquid - Chromatography-Mass Spectrometry/Mass Spectrometry (LC/MS/MS), verifies the presence of drug metabolites and dispels false positives.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can indicate drug usage for up to 90 days, unlike urine tests with a shorter span.
• Difficulty to cheat: Cheating on a hair drug test is extremely challenging, enhancing result accuracy.
• Provides historical data: It can reveal a drug use pattern over time, not merely recent use.

Limitations:

• Cannot detect recent use: Drugs require about 5-7 days to become traceable in hair.
• Cost: Hair drug tests typically carry higher costs than other testing methods.
• Variations in results: Elements such as hair color and personal differences in hair growth can impact drug metabolite concentrations in the hair.

Note: Frequently branded as "hair follicle tests", the analysis pertains to the hair strand itself, not the follicle beneath the scalp.

Why is Hair Follicle Drug Testing Important

Why Hair Follicle Testing Beats Other Forms of Testing in Texas

• Hair follicle testing offers superior detection accuracy compared to the URINE tests, providing an extended detection window of up to 90 days, crucial for employers seeking long-term drug use insights.
• While URINE tests might miss sporadic drug use, hair testing ensures a comprehensive overview, capturing consistent drug use patterns, which can be pivotal in maintaining workplace safety and reliability.
• The reliability of hair follicle testing diminishes opportunities for test tampering, unlike URINE tests, which are more susceptible to manipulation, thus ensuring more dependable results for Texas employers.
• In a state as vast as Texas, our hair follicle testing is well-supported with 1,645 centers, ensuring consistent and accessible service throughout 2,698 cities, setting us apart from conventional testing methods.
• Moreover, hair testing's non-invasive nature and comprehensive results surpass the limitations of traditional URINE testing, making it the preferred choice for discerning Texas employers.
