Hair Follicle Drug Testing - Lebanon, OH

What it is, How it works

The examination of hair has emerged as an effective means for identifying drug and alcohol consumption. Hair serves as a record of long-term usage by capturing biomarkers within the fibers of the continuously growing hair. When samples are taken close to the scalp, hair can offer a detection window that extends up to roughly three months for both drugs and alcohol. The collection process for hair is straightforward, somewhat resistant to tampering, and uncomplicated to send.

A hair sample measuring 1.5 inches and comprising approximately 200 strands (comparable to the diameter of a #2 pencil) taken nearest to the scalp provides 100mg of hair, which is the preferred amount for preliminary exams and thorough analysis. For additional tests like EtG or for analyses beyond 10 panels, a specimen weighing 150mg is advisable. Utilizing a jeweler's scale for weighing is suggested. In cases where scalp hair isn't available, a comparable volume of body hair can be used. References to head hair indicate only scalp hair. Body hair encompasses all other types (such as facial, axillary, etc.).

Process Overview

The pivotal stages in processing a laboratory drug test result encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the primary phase where a sample is entered into a laboratory’s framework. This process ascertains that the sample has been sealed and transported correctly, assigns it a unique LAN (Laboratory Accessioning Number), and completes any additional data entry omitted by an electronic chain of custody system.

Screening involves a preliminary assessment for substance misuse. Although Screening is a cost-efficient method to exclude drug use for most samples, a verified positive finding is mandatory for legal acceptability. Samples yielding a presumptively positive result in Screening necessitate further confirmation.

Samples with a presumptive positive outcome during the Screening phase are subjected to further specimen collection and undergo preparatory steps for Extraction. In this stage, drugs are isolated from hair at concentrations significantly lower than those in other methods (e.g., urine or oral fluids), rendering hair drug analysis the most challenging to conduct.

Confirmation of any positive result from Screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples that preliminarily test positive undergo washing before confirmation is executed where necessary. The entire laboratory sequence from Accessioning through Confirmation is scrutinized in accordance with both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug usage for as long as 90 days, whereas urine tests offer a shorter detection timeframe.
• Resistance to manipulation: Efforts to cheat on a hair drug test are notably challenging, contributing to the test's reliability.
• Chronological data provision: It reveals patterns of drug use over extended durations, rather than just recent consumption.

Limitations:

• Ineffectiveness for recent detection: Drugs only become detectable in hair after approximately 5-7 days.
• Expense: Hair drug analyses tend to cost more than alternative drug testing methodologies.
• Result variability: Influencing factors such as hair color and individual growth rates can impact the concentrations of drug fragments in hair.

Note: Common terminology may label these as "hair follicle tests," but the analysis focuses on the hair strands, not the follicles beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing in Lebanon, OH, surpasses urine tests by providing superior detection accuracy and reliability.
