Hair Follicle Drug Testing - Davis, NC

What it is, How it works

Hair testing is increasingly recognized as an effective method for detecting drug and alcohol consumption. Hair records a prolonged history of alcohol and drug intake by encapsulating biomarkers within the fibers of the developing hair strand. When taken near the scalp, hair can offer up to a roughly 3-month period for detecting alcohol and drugs. Hair collection is straightforward, somewhat challenging to tamper with, and easy to transport.

A 1.5-inch segment of about 200 hair strands (about the size of a #2 pencil) near the scalp will provide 100mg of hair, the optimum sample for screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the sample is advisable. We suggest weighing the sample on a jeweler’s scale. If scalp hair can't be obtained, a corresponding amount of body hair may be collected. When mentioning head hair, it specifically refers to scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result consists of four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary handling of a sample into a laboratory's system. This step involves confirming that the sample was properly sealed and transported, giving a random LAN (Laboratory Accessioning Number), and completing any data entry not covered by an electronic chain of custody system.

Screening includes an initial rapid assessment for drugs of abuse. Although Screening is a cost-efficient way to dismiss drug use in most samples, a positive screen necessitates confirmation to be court-admissible. Any samples showing presumptive positivity in Screening require a follow-up confirmation.

If a sample shows presumptive positivity in the Screening, additional hair is taken from the original specimen for Extraction. In this stage, drugs are removed from hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to execute.

Confirmation of any positive screening result is completed through GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples are cleansed prior to confirmation if needed. The entire laboratory procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, in contrast to urine tests which offer a shorter detection timeframe.
• Challenging to cheat: It is notably difficult to deceive a hair drug test, thereby enhancing result reliability.
• Offers historical data: It can illustrate a pattern of drug use over time, rather than just recent usage.

Limitations:

• Inability to detect recent use: It takes roughly 5-7 days for drugs to be noticeable in hair.
• Higher cost: Hair drug tests tend to be more pricey than alternate drug testing techniques.
• Result fluctuations: Elements like hair color and individual differences in hair growth can impact the concentration of drug metabolites in hair.

Note: While commonly called "hair follicle tests", the examination actually analyzes the hair strand and not the hair follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing in Davis, NC, surpasses urine testing due to its greater detection accuracy and reliability. Unlike urine tests, hair analyses can reveal drug use up to 90 days prior, offering a comprehensive overview of an individual's substance history. This extended detection period ensures that employers and authorities gain a clearer picture of patterns, enhancing decision-making.

Compared to urine tests, hair follicle analyses provide a more reliable account of substance use. The resistance of hair testing to tampering and environmental factors makes it a secure method for drug detection. This reliability provides employers with the confidence needed to maintain drug-free workplace policies effectively.
