Hair Follicle Drug Testing - Potomac Mills, VA

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair offers an extended record of alcohol and other drugs by encapsulating biomarkers within the strands' fibers as they grow. When sourced near the scalp, hair can reveal up to a roughly three-month detection window for alcohol and other substances. Collection is straightforward, it's somewhat resistant to tampering, and easily portable.

A 1.5-inch section comprising approximately 200 hair strands (about the diameter of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal sample size for both screening and verification. For EtG, additions, and/or analyses beyond 10 panels, 150mg of the sample is suggested. We advocate for weighing the sample on a jeweler’s scale. If scalp hair cannot be obtained, an equivalent quantity of body hair may be used. When mentioning head hair, we specifically mean scalp hair only. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

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

Accessioning includes the preliminary handling of a sample within a laboratory's system. This step involves confirming that the sample was sealed and delivered correctly, allocating a random LAN (Laboratory Accessioning Number), and finalizing any further data entry absent from an electronic chain of custody system.

Screening is a preliminary rapid assessment for drugs of abuse. Though Screening is a cost-efficient method to exclude drug use on most samples, a positive screen must be confirmed to be valid in legal settings. Any samples that show a presumptive positive in Screening require an additional confirmation.

Should a sample test presumptively positive in the screening phase, more hair is extracted from the initial sample and processed for Extraction. In this phase, drugs are drawn from hair at a much lower concentration than other methods (e.g., urine or oral fluid), making hair drug screening the most intricate method to execute.

A positive screening result is verified through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo cleaning prior to confirmation if needed. The entire lab procedure, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair standard and the accreditation in line with ISO / IEC 17025 requirements.

Advantages of hair drug testing:

• Prolonged detection window: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which cover a shorter detection timeframe.
• Hard to falsify: It is exceedingly challenging to deceive a hair drug test, enhancing result accuracy.
• Historic data provision: It offers a pattern of drug use over time, rather than merely recent consumption.

Limitations:

• Inability to detect recent consumption: It takes about 5-7 days for drugs to be noticeable in hair.
• Expense: Hair drug tests are usually pricier compared to other drug testing techniques.
• Result variability: Variables like hair color and individual disparities in hair growth can influence drug metabolite concentrations in hair.

Note: Frequently mistaken as "hair follicle tests", the procedure itself analyzes the hair strand and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing in Potomac Mills, VA undeniably outperforms traditional urine tests due to its superior detection accuracy. While urine tests are limited to short-term detection, hair testing captures a longer history of substance use, offering extensive insights into an individual's habits.
