Hair Follicle Drug Testing - Turin, IA

What it is, How it works

Recognized as a robust instrument for detecting substance and alcohol consumption, hair testing has gained prominence. By embedding biomarkers within the strands of developing hair, a comprehensive long-term record of substance use is obtainable. A sample sourced near the scalp is capable of offering up to a 3-month observational window for alcohol and other substances. The simple collection process, challenging adulteration, and uncomplicated shipping make hair an optimal choice.

Approximately 1.5 inches of around 200 hair strands (comparable to a #2 pencil's diameter) next to the scalp will yield around 100mg, the recommended sample for both initial screenings and confirmations. For EtG, additional assessments, or screenings beyond 10 panels, a quantity of 150mg of specimen is advocated. We suggest measuring the specimen using a jeweler’s scale. If scalp hair is unavailable, a comparable volume of body hair can be used. "Head hair" is defined as scalp hair solely, whereas "body hair" encompasses other variations such as facial or axillary hair.

Process Overview

The fundamental laboratory procedures of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial integration of a sample into a laboratory’s framework. This phase ensures proper sealing and shipping, assigns a unique LAN (Laboratory Accessioning Number), and completes ancillary data entry that may not be included within an electronic chain of custody framework.

Screening allows for a swift preliminary assessment for substance abuse. Although Screening is economical and beneficial in eliminating potential drug usage in most samples, confirmation is necessary for legal admissibility. Samples presenting a presumptive positive in the Screening necessitate a subsequent validation.

Presumptively positive samples at the Screening juncture are further processed from the original specimen for Extraction. Here, the removal of drugs from hair is executed at concentrations significantly lower compared to other techniques (e.g., urine or oral fluid), establishing hair drug screening as notably challenging.

Affirmation of any positive screening outcome is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. Samples with presumptive positives are cleansed before confirmation if necessary. The comprehensive laboratory procedure covering Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation alongside ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extensive detection timeframe: Hair drug assessments uncover drug usage for up to 90 days, as opposed to urine examinations which possess a narrower detection span.
• Resistant to falsification: Circumventing a hair drug assessment is exceedingly challenging, resulting in heightened result precision.
• Delivers historical insights: Capable of indicating a usage pattern over a duration, rather than merely indicating recent consumption.

Limitations:

• Incapable of identifying recent usage: Detection of drugs within hair requires approximately 5-7 days.
• Expense: Hair drug evaluations typically incur greater costs compared to alternative testing approaches.
• Result variability: Elements such as hair pigmentation and individual hair growth variability can influence the drug metabolite concentration within the hair.

Note: The term "hair follicle tests" is commonly used, though the analysis is conducted on the hair strand, not the follicle beneath the scalp.
