Hair Follicle Drug Testing - Zafra, OK

What it is, How it works

Hair analysis is now recognized as a robust method for identifying drug and alcohol consumption. The hair serves as a record of prolonged substance usage by embedding biomarkers within its strands as it grows. When trimmed near the scalp, hair can reveal drug and alcohol usage within roughly a three-month timeframe. Hair collection is straightforward, hard to tamper with, and straightforward to transport.

A 1.5-inch hair segment comprising around 200 strands (approximately the thickness of a #2 pencil) closest to the scalp yields 100mg, the optimal sample for evaluation and verification. For EtG, additional tests, and/or assessments exceeding 10 panels, a 150mg specimen is advised. Utilizing a jeweler’s scale for weighing the specimen is recommended. If scalp hair is absent, body hair equivalent in quantity can be gathered. "Head hair" specifically refers to scalp hair exclusively, whereas "body hair" denotes all other hair forms (facial, axillary, etc.).

Process Overview

The laboratory processing of drug test outcomes encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary handling of a sample within a laboratory’s framework. This step entails verifying the sample’s proper sealing and shipment, allocating a random LAN (Laboratory Accessioning Number), and finalizing any pending data entry absent from an electronic chain of custody apparatus.

Screening involves a preliminary assessment to detect drugs. While Screening serves as an economical method to rule out drug use in most samples, a positive screen necessitates confirmation for legal admissibility. Samples that test presumptively positive during Screening require a subsequent confirmation.

For samples that show presumptive positivity at the Screening phase, further hair is extracted from the initial sample for Extraction. In this phase, drugs are isolated from hair at substantially diminished concentrations compared to alternative methods (such as urine or oral fluid), thus depicting hair drug screening as the most challenging protocol to execute.

Positive screening results undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Samples presumed positive are subjected to washing ahead of confirmation where appropriate. The comprehensive laboratory process spanning from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair classification and accreditation to ISO / IEC 17025 norms.

Advantages of hair drug testing:

• Extended detection period: Hair drug exams can trace drug usage over a span of up to 90 days, unlike urine tests that have briefer detection periods.
• Cheating resistance: Cheating a hair drug exam is exceedingly difficult, ensuring higher accuracy of results.
• Data history provision: It uncovers a timeline of drug consumption over a defined timeframe, not merely recent use.

Limitations:

• Incapable of detecting recent drug consumption: Drugs take close to 5-7 days to become traceable in hair.
• Expense: Hair drug tests tend to be pricier compared to other testing methodologies.
• Result variability: Variables like hair coloration and personal hair growth differences can influence the levels of drug metabolites in the hair.

Note: Frequently mislabeled as "hair follicle tests," the evaluation actually targets the hair strand rather than the follicle beneath the scalp.
