Mold Symptoms

Mold symptoms can range from moderate to severe. Both the U.S. Centers for Disease Control (CDC) and the U.S. Environmental Protection Agency (EPA) have classified mold toxins as cancer causing. The health effects can vary greatly depending on 4 risk factors, below is a brief description of each one.

Mold Spore Levels

Mold Spore Levels

Concentrated amounts of mold spores can amplify mold symptoms. When preforming air quality testing, elevated mold spore counts are defined as the indoor levels of mold spores being at higher levels than naturally occurring outdoors. Often the higher an environments mold spore count, the more severe mold symptoms can become.

Mold Exposure Time

Time of Mold Exposure

Prolonged mold exposure can lead to a host of mold symptoms including mycotoxicosis. Mold fine and ultra-fine particulates build up in the human body over time. Often the longer you are in a mold contaminated environment the higher your risk factors become for more severe health effects.

Mold Toxins

Mold Toxins

Mold toxins have been connected to some of the most harmful mold symptoms. Mold will produce toxins at different points of its life cycle. A dangerous toxin that comes from mold are mycotoxins. Mycotoxins will attach to fine and ultra-fine mold spore particulates making them extremely difficult to remove from the human body. Mycotoxins have been classified as a carcinogen (cancer causing) by the CDC and EPA.

Immune System

Immune System

Mold can affect everyone’s immune system in drastically different ways. Your immune system will dictate mold symptoms such as allergic reactions and invasive fungal infections. It is not uncommon for one member of the household to have more adverse mold symptoms than another. If left untreated mold exposure can lead to a lowered or compromised immune system.

Health & environment connections

Health & Environmental Connections

Establishing a true connection between a mold contaminated environment and the health effects you’re experiencing is possible with the correct testing approach. Working closely with the medical community we have found the most effective method is a combination of medical and environmental tests.

This testing gives you the ability to be run both medically and environmentally. The health symptoms for mold exposure can range from moderate to severe depending on the species of mold and the toxins it is producing. Medical testing in conjunction with environmental testing may be necessary to definitively identify mold sickness.

The long-term effects of mold exposure can result in mycotoxicosis, neurological disorders, severe breathing disorders, and fungal infections. Exposure severity will depend on the species of mold, amount of time in the contaminated environment, volume of spores, and an individual’s immune system.

Mold can make you sick in 3 ways (1) allergic reaction (2) Invasive fungal infection (3) Mycotoxin poisoning. The amount of time it takes to experience any of these ailments will vary greatly upon an individual’s immune system, but studies have found that prolonged exposure to mold will generally result in some form of adverse health effect.

Some of the commonly prescribed medical tests for mold sickness are Mycotoxin testing, IGE testing, Scratch Allergy testing GI testing, and DNA testing. Your doctor will often use your environmental report to identify the appropriate corresponding medical test
