Hair Follicle Drug Testing - Big Falls, MN

What it is, How it works

Hair testing has emerged as a robust method for identifying drug and alcohol consumption. Hair strands encapsulate a prolonged history of alcohol and other substances by securing biomarkers within the fibers of the developing hair. When gathered near the scalp, hair can offer up to roughly a 3-month detection timeframe for alcohol and other substances. Hair collection is straightforward, relatively hard to alter, and convenient to transport.

A 1.5-inch section of roughly 200 hair strands (approximately the size of a #2 pencil) nearest to the scalp will yield 100mg of hair, the optimal sample for analysis and validation. For EtG, additional components, and/or examinations covering more than 10 panels, 150mg of the specimen is advisable. It is suggested to weigh the specimen using a jeweler's scale. If scalp hair is inaccessible, a comparable quantity of body hair may be utilized. When referencing head hair, it strictly pertains to scalp hair. Body hair encompasses all other types (facial, auxiliary, etc.).

Process Overview

The laboratory workflow for processing a drug test result encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary introduction of a sample into a laboratory's system. This process verifies the sample's proper sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and completes any supplementary data entry absent from an electronic chain of custody system.

Screening encompasses a preliminary swift assessment for drugs of abuse. Though Screening is economical for excluding drug usage in the majority of samples, a positive result necessitates confirmation for courtroom admissibility. Any samples with a presumptive positive in Screening require subsequent confirmation.

If a sample is presumptively positive in the Screening phase, more hair is extracted from the original specimen and readied for Extraction. In this phase, drugs are drawn out from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), rendering hair drug screening the most intricate methodology to execute.

Confirmation of any positive result from Screening is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed before confirmation as required. The entire laboratory process from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and compliance with ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug assessments can track drug usage for up to 90 days, in contrast to urine evaluations which cover a narrower window.
• Difficulty to manipulate: Cheating a hair drug test is exceedingly challenging, enhancing result accuracy.
• Offers historical insights: It can reveal a pattern of drug usage over time, not merely recent usage.

Limitations:

• Inability to detect recent usage: It takes about 5-7 days for drugs to manifest in hair.
• Expense: Hair drug examinations are typically costlier than alternative testing approaches.
• Result variation: Elements like hair color and individual differences in hair growth can influence the level of drug metabolites in hair.

Note: Despite the common reference as "hair follicle tests," the analysis is of the hair strand, excluding the follicle beneath the scalp.
