Hair Follicle Drug Testing - Stone Ridge, VA

What it is, How it works

Hair analysis has become recognized as a robust method for identifying drug and alcohol consumption. Hair can serve as a long-term record for alcohol and other substances by encapsulating biomarkers within the fibers of the hair as it grows. When obtained near the scalp, hair can offer up to nearly a 3-month detection period for alcohol and illicit substances. Hair is easy to collect, relatively hard to tamper with, and convenient to transport.

A sample measuring 1.5 inches and consisting of about 200 hair strands (approximately the diameter of a #2 pencil) close to the scalp will yield 100mg of hair, which is perfect for both screening and confirmation tests. For EtG, additional panels, and/or tests beyond 10 panels, 150mg of the sample is suggested. It is advisable to measure the sample using a jeweler’s scale. If scalp hair is not available, an equivalent quantity of body hair can be gathered. In the context of head hair, we specifically mean scalp hair. Body hair includes all other types (such as facial, axillary, etc.).

Process Overview

There are four primary steps in processing a drug test result in the lab: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first step where a sample is processed into the laboratory’s system. This entails verifying that the sample was appropriately sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any extra data entry not captured by an electronic chain of custody system.

Screening entails an initial rapid check for drugs of abuse. While Screening is a cost-effective approach to exclude drug use in most samples, any positive results require confirmation for them to be used in court. Samples that test presumptively positive in Screening necessitate a secondary validation.

For samples that are presumptively positive during Screening, more hair is extracted from the initial sample and prepared for Extraction. At this phase, drugs are extracted from hair at a significantly lower concentration than other methods (such as urine or oral fluid), making hair drug screening a more challenging methodology to execute.

Confirmation of any positive screening result is done using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that test presumptively positive are cleansed prior to confirmation if needed. The comprehensive laboratory process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a more limited detection period.
• Challenging to deceive: It is quite challenging to trick a hair drug test, thus ensuring more precise results.
• Offers historical insight: It can reveal a trend of drug use over time, not just recent consumption.

Limitations:

• Incapable of detecting recent use: It typically takes 5-7 days for drugs to become traceable in hair.
• Expense: Hair drug tests often cost more compared to other drug testing methods.
• Result variability: Elements such as hair color and personal differences in hair growth can influence the concentration of drug metabolites within the hair.

Note: Although commonly called "hair follicle tests", the test itself examines the hair strand and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

When comparing hair follicle testing to traditional urine testing in Stone Ridge, VA, the advantages are clear. Hair tests boast a longer detection period, identifying substance use up to 90 days post-consumption, while urine tests primarily cover recent use within a short timeframe.

The superior reliability of hair testing, enhanced by the impossibility of sample tampering, positions it as a more robust method, especially for environments with zero-tolerance policies.

Extended Detection Window

Hair follicle testing in Stone Ridge, VA, offers an extended detection window of up to 90 days, far surpassing other testing methods. This allows employers a comprehensive view of an individual's substance use history.

Such an extensive detection period ensures that organizations and professionals can make informed decisions based on a more complete understanding of an applicant or employee's historical substance use.

Tamper-Resistant Testing Method
