Hair Follicle Drug Testing - Bristol, VA

What it is, How it works

Hair testing is regarded as an effective method for identifying drug and alcohol consumption. Hair retains a prolonged record of substances by encapsulating biomarkers within the strands as it grows. When gathered near the scalp, it can offer up to a 3-month detection span for alcohol and drugs. Hair collection is straightforward, not easily tampered with, and convenient for shipping.

A specimen of 1.5 inches comprising roughly 200 hair strands (comparable to the thickness of a #2 pencil) adjacent to the scalp yields 100mg, which is an optimal amount for screening and validation. For EtG, add-ons, and tests exceeding 10 panels, a recommendation of 150mg is made. It is advised to use a jeweler’s scale for weighing the sample. If scalp hair is unavailable, an equivalent amount of body hair can be used. The term head hair specifically denotes scalp hair, whereas body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory procedure for processing a drug test outcome consists of four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase where a sample is integrated into a laboratory system. This stage involves ensuring the sample's proper sealing and shipment, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data entry absent from an electronic chain of custody system.

Screening serves as a preliminary review for the presence of drugs. While it is a cost-efficient method to eliminate drug presence in most samples, court admissibility requires confirming a positive result through further analysis. A positive outcome in Screening necessitates subsequent confirmation.

Presumptively positive samples during Screening require additional hair from the original specimen for Extraction, where substances are extracted from hair at notably lower concentrations compared to alternative methods (such as urine or oral fluid), highlighting the complexity of hair drug screening.

Confirmation of any positive screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive specimens undergo necessary washing before confirmation. The entire process from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair standards and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection span: Hair drug tests can identify drug use for up to 90 days, while urine tests have a shorter duration.
• Challenging to deceive: Hair drug tests are difficult to manipulate, ensuring more reliable outcomes.
• Reveals usage pattern: Provides a history of substance use over time, rather than only recent usage.

Limitations:

• Inability to identify recent use: Detectability of drugs in hair takes approximately 5-7 days.
• Expense: Hair drug tests generally incur higher costs than other testing approaches.
• Result variability: Factors like hair color and individual differences in hair growth can influence drug metabolite concentration.

Note: Although commonly called "hair follicle tests", the analysis focuses on the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing offers significant advantages over traditional urine tests in Bristol, VA. Its ability to detect a wide range of substances makes it ideal for workplace settings where drug use must be monitored closely. The results from hair tests are more reliable and less susceptible to tampering, ensuring zero-tolerance policies are effectively enforced.
