Hair Follicle Drug Testing - Hilham, TN

What it is, How it works

Hair analysis is increasingly regarded as an effective means for identifying drug and alcohol consumption. By encasing biomarkers within the hair fiber, it furnishes a long-standing record of substance usage. When sourced near the scalp, it offers a possible detection timeframe for various drugs and alcohol extending up to around 90 days. Hair is effortless to collect, comparatively resistant to tampering, and straightforward to transport.

Securing a 1.5-inch section that contains approximately 200 hairs (approximately the thickness of a #2 pencil) nearest the scalp yields an optimal 100mg for assessment and validation. To accommodate EtG, supplementary, or tests beyond 10 panels, 150mg of hair is advisable. It is beneficial to measure the sample using a jeweler’s balance. In the absence of head hair, a corresponding quantity of body hair can be fetched. "Head hair" pertains solely to scalp hair, whereas "body hair" covers all other hair types (facial, axillary, etc.).

Process Overview

There are four primary phases in the laboratory evaluation of a drug test: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of the specimen into a lab's framework. Tasks include confirming the seal and shipment integrity, assigning a random LAN (Laboratory Accessioning Number), and executing any missing data entry not captured by an electronic chain of custody system.

Screening offers a preliminary rapid assessment for substance abuse. While Screening is a budget-friendly approach to eliminate drug use on most samples, any positive result requires validation for judicial acceptance. Samples testing presumptive positive in Screening necessitate further confirmation.

For samples indicating presumptive positivity during Screening, more hair is extracted from the initial sample and readied for Extraction. This phase extracts substances from hair with a much smaller concentration than alternative methods (e.g., urine or oral fluid), emphasizing why hair drug evaluation is highly challenging to execute.

Confirmation of any positive screening outcome is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive specimens undergo necessary cleansing. The comprehensive lab process from Accessioning to Confirmation adheres to CAP (College of American Pathologists) Hair classification and accreditation following ISO / IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection period: Hair drug evaluations can sense drug utilization over a span of up to 90 days, whereas urine tests possess a limited detection period.
• Challenging to manipulate: Due to its resistance to tampering, a hair drug test provides more trustworthy outcomes.
• Reveals historical usage: It yields a pattern of drug use spanning a timeline, beyond merely recent usage.

Drawbacks:

• Incipient usage detection: Drugs take an estimated 5-7 days to become identifiable in hair.
• Expense: Hair drug evaluations tend to be pricier compared to alternative testing techniques.
• Result variability: Attributes such as hair pigmentation and individual differences in hair growth can influence drug metabolite concentration within the hair.

Remark: Although often termed "hair follicle tests", the testing process actually examines the hair strand rather than the follicle beneath the scalp.
