Hair Follicle Drug Testing - New Castle, VA

What it is, How it works

Hair analysis is recognized as an effective method for detecting drug and alcohol consumption. It captures a comprehensive timeline of substance use by embedding biomarkers within the hair strands as they grow. Hair collected near the scalp can offer a detection period of up to about three months for alcohol and certain drugs. The collection process is straightforward, making it somewhat challenging to tamper with, and transport is uncomplicated.

Collecting a 1.5-inch sample of around 200 hair strands (equivalent to the girth of a #2 pencil) near the scalp equates to 100mg, which is optimal for both initial screening and confirmatory tests. For EtG, supplementary tests, or those exceeding 10 panels, 150mg of the sample is advisable. It's recommended to weigh the sample using a jeweler’s scale. If scalp hair is not present, an equivalent amount of body hair can be used. References to head hair pertain solely to scalp hair, while body hair encompasses all other types (facial, axillary, etc.).

Process Overview

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

During Accessioning, a sample is initially processed into the laboratory system. This includes confirming the sample's seal and appropriate shipment, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any supplemental data entry absent from an electronic chain of custody system.

Screening performs a rapid initial check for drug abuse. Although cost-effective for ruling out drug use in most samples, a positive screen must be confirmed for court validity. Samples indicating a presumptive positive need a subsequent confirmation.

Presumptive positives in the Screening stage trigger additional hair to be extracted from the sample for further analysis in the Extraction phase. Here, drugs are extracted from hair at concentrations much lower than other methods (e.g., urine or oral fluid), making it one of the most challenging testing methodologies.

Positive screening results undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, samples showing presumptive positives are washed as necessary. The complete laboratory process, from Accessioning to Confirmation, is scrutinized under CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair testing can identify drug consumption over a 90-day period, unlike urine tests with shorter detection spans.
• Resistant to tampering: Manipulating a hair drug test is quite difficult, enhancing the accuracy of results.
• Tracks historical usage: It provides usage trends over a timeframe, beyond just recent consumption.

Limitations:

• Incapable of detecting recent consumption: Detections typically require 5-7 days post-use to appear in hair.
• Expense: Hair drug tests tend to be pricier compared to alternative methods.
• Result variations: Factors like hair color and individual hair growth rates can influence drug metabolite concentrations in hair.

Note: Although often called "hair follicle tests," analysis is performed on the hair strand itself, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In New Castle, VA, hair follicle testing surpasses traditional urine tests in several ways. The extended detection window allows for a thorough review of an individual's substance use over a prolonged period. This provides a distinct advantage by capturing a wider range of substance history compared to urine tests, which are limited to a shorter timeframe.

Moreover, hair testing boasts an unparalleled detection accuracy, reducing the chance of disingenuous results. Employers, legal systems, and individuals benefit from the tests' robustness, ensuring that adherence to drug-free mandates is thoroughly monitored and upheld, unlike more transient urine testing.

Extended Detection Window

This expansive timeframe provides a more comprehensive account of an individual's drug usage history, making it an ideal tool for employers looking to understand an applicant or current employee's past substance behavior.

Thanks to the prolonged detection period, hair follicle tests offer a longitudinal perspective, capturing episodic substance use that might otherwise be missed by other test types. This ability to view past usage ensures a thorough assessment for compliance or hiring decisions, far exceeding shorter windows of alternative testing methods.

Tamper-Resistant Testing Method
