Hair Follicle Drug Testing - St. Charles, MD

What it is, How it works

Recognized as an effective method for identifying drug and alcohol consumption, hair testing captures biomarkers within the fibers of hair strands as they grow, offering a historical footprint of substance usage. When gathered near the scalp, this type of test can provide a detection period extending up to roughly three months. The collection process is straightforward, tampering is less feasible, and it facilitates easy shipping.

A sample measuring 1.5 inches, consisting of roughly 200 hair strands (similar to the width of a #2 pencil) taken nearest to the scalp will yield 100mg of hair, which is ideal for both screening and verification. For more detailed tests, such as EtG, add-ons, or panels exceeding ten, a specimen amount of 150mg is advised. We suggest utilizing a jeweler’s scale for weighing the specimen. In cases where scalp hair is unavailable, an equivalent quantity of body hair may be used. "Head hair" specifically denotes scalp hair, while "body hair" encompasses any other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test involves four major steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step of incorporating a sample into the laboratory's workflow. It includes ensuring the sample's proper sealing and shipment, assigning a Laboratory Accessioning Number (LAN) at random, and completing any additional information entry absent from an electronic chain of custody system.

Screening initiates a preliminary assessment for substances of abuse. Although Screening is an economical means to evaluate the majority of samples for drug use, positive results from this step require confirmation to be considered valid in legal settings. Any samples flagged as presumptively positive in Screening necessitate secondary confirmation.

For samples indicated as presumptively positive during Screening, additional hair is extracted from the original sample set and readied for Extraction. Here, drugs are isolated from the hair at much lower concentrations than those found in alternative approaches (e.g., urine or oral fluids), making hair drug testing a challenging methodology to execute.

Positive results from the Screening phase are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples labeled as presumptively positive undergo a wash before moving to Confirmation as required. The full laboratory process, from Accessioning to Confirmation, undergoes evaluation under the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug use up to 90 days preceding, unlike urine tests which offer a shorter timeframe for detection.
• Difficult to tamper: Cheating a hair drug test is notably challenging, thus enhancing result accuracy.
• Historical usage pattern: Hair testing identifies habitual drug use over time, beyond just recent consumption.

Limitations:

• Incapable of detecting recent drug intake: A timeframe of approximately 5-7 days is required for drugs to become traceable in hair.
• Expense: Generally, hair drug tests incur higher costs compared to alternative testing approaches.
• Result variability: Drug metabolite concentrations in hair can be impacted by factors such as hair pigmentation and individual hair growth rates.

Note: Although occasionally referred to as "hair follicle tests", the actual analysis is conducted on the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Choosing hair follicle testing over traditional urine tests in St. Charles, MD, reveals numerous benefits. Hair tests demonstrate superior detection accuracy and reliability, capturing a more profound history of substance use.
