Hair drug testing, commonly called hair follicle drug testing, is an analytical technique for identifying drug usage by examining hair specimens.

How it works:

• Drug enters bloodstream: Upon drug consumption, the substance and its metabolites (byproducts of metabolism) find their way into the bloodstream.
• Drugs reach hair follicles: With each hair follicle connected to a blood vessel, the drugs move through the blood and into the hair follicle.
• Drugs get trapped in hair: As the hair develops, these tiny quantities of substances become embedded within the cortex of the hair strand.
• Hair sample collection: Hair is sampled, generally from the scalp (or from body hair if scalp hair is inadequate).
• Lab analysis: The collected hair sample is dispatched to a laboratory for analysis.
  • Screening: An introductory Enzyme-Linked Immunosorbent Assay (ELISA) is administered to detect drug metabolites.
  • Confirmation: Should the ELISA yield a positive result, a more precise confirmation test like Gas Chromatography-Mass Spectrometry (GC/MS) or Liquid - Chromatography-Mass Spectrometry/Mass Spectrometry (LC/MS/MS) is conducted to verify drug metabolite presence and eliminate erroneous positives.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can identify drug consumption for up to 90 days, unlike urine tests which have a shorter detection period.
• Difficulty to cheat: It is quite challenging to deceive a hair drug test, enhancing result accuracy.
• Provides historical data: It offers a record of drug usage over time, rather than just recent use.

Limitations:

• Cannot detect recent use: It takes about 5-7 days for drugs to become detectable in hair.
• Cost: Hair drug tests often cost more than other drug testing techniques.
• Variations in results: Elements like hair color and individual hair growth differences can influence the concentration of drug metabolites in the hair.

Note: Though frequently termed "hair follicle tests", the analysis is conducted on the hair strand rather than the follicle beneath the scalp.

Why is Hair Follicle Drug Testing Important

Why Hair Follicle Testing is Superior to URINE Testing in Tennessee

• Hair follicle testing offers a broader detection window, identifying drug use for up to 90 days, compared to the much shorter detection period of URINE testing.
• It eliminates the possibility of tampering or contamination, providing more reliable and accurate results.
• Employers benefit from the superior detection accuracy, allowing for better-informed decisions ensuring a drug-free workplace.
• Even with varying drug usage patterns, hair follicle testing is adept at capturing long-term drug habits, unlike short window methods.
• Hair follicle testing provides a true reflection of an individual’s drug use history, making it an essential tool for compliance and safety checks.
