Hair Follicle Drug Testing - Clare, LA

What it is, How it works

Hair assessments have evolved into a crucial method for identifying drug and alcohol consumption. Hair captures a prolonged timeline of substances by securing biomarkers within the strands' fibers as they grow. When hair is clipped near the scalp, it can offer a detection window of around three months for alcohol and other substances. Hair collection is uncomplicated, relatively tamper-resistant, and convenient to transport.

A 1.5-inch snippet comprising roughly 200 hair strands (approximately the width of a #2 pencil) situated closest to the scalp yields 100mg, the preferred amount for both screening and verification. For EtG, supplementary analyses, and/or examinations beyond 10 panels, it's advisable to use 150mg of the sample. We suggest utilizing a jeweler’s scale for specimen measurement. Should scalp hair not be obtainable, a comparable amount of body hair can be used. When we mention head hair, it specifically refers to scalp hair only. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Summary

The laboratory journey of processing a drug test result involves four principal stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary processing of a specimen into a lab's system. This step verifies the sample's proper sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data entry absent in an electronic custody chain system.

Screening constitutes a preliminary rapid assessment for drug misuse. While Screening offers an economical method to exclude drug consumption for most samples, a positive result in Screening mandates confirmation for legal admissibility. Any samples with presumed positivity in Screening necessitate further validation.

If a sample shows presumed positivity at the Screening stage, additional hair is extracted from the initial sample and readied for Extraction. During Extraction, drugs are retrieved from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug testing the most challenging methodology to execute.

Confirmation of any positive Screening outcome is accomplished via GC/MS, GC/MS/MS, or LC/MS/MS. All presumed positive samples undergo washing pre-confirmation as required. The comprehensive laboratory workflow from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair classification and accreditation to ISO / IEC 17025 standards.

Benefits of hair drug testing:

• Extensive detection timeframe: Hair drug tests can identify drug use for up to 90 days, contrasting with the shorter detection period of urine tests.
• Cheating deterrence: Hair drug tests are notably resistant to manipulation, assuring more precise outcomes.
• Historical insights: This method can illustrate a pattern of drug usage over time, rather than just recent consumption.

Drawbacks:

• Incapacity to recognize recent usage: Drugs require approximately 5-7 days to become detectable in hair.
• Expense: Generally, hair drug tests have a higher cost compared to other testing strategies.
• Result disparities: Variables like hair color and personal variations in hair growth influence drug metabolite concentration in hair.

Note: Despite frequently being termed "hair follicle tests", the analysis is on the hair strand and not the follicle beneath the scalp.
