Exposure Tests

Exposure testing is important because chemical hazards and toxic substances pose a wide range of health hazards and human parasitic infections often go unnoticed or are misdagnosed.

Toxins are poisonous and extremely harmful substances, which causes potential harm to the various organs in the body. Liver and kidney sustain the damage and the toxin build up starts forming in the blood. And once this happens, there are strong and severe symptoms that start developing. The only way in which toxins can be checked in the blood is through blood tests. Heavy metal toxicity can result in damage to the vital organs, neurological and muscular degeneration, cancer, allergies and even death.

Occupational exposure is the most common way people are exposed to heavy metals but other ways exposure happens is through environmental releases in the air, water and soil, intentional poisoning, living in or remodeling old homes, cigarette smoke, contaminated soil, ingestion, or taking metal-based supplements at unnecessary levels.

Heavy metal testing is recommended for anyone who believes they have had exposure in the workplace or through other means especially if they are exhibiting symptoms of heavy metals poisoning.  Family members of those exposed in the workplace should also be tested as toxic particulates can be brought into the home on clothing.

Millions of Americans develop parasitic infections and symptoms often go unnotices or are misdiagnosed.  An infection can lead to serious health problems, including blindness, pregnancy complications, seizures, heart failure, and even death.

Many kinds of lab tests are available to diagnose parasitic diseases.  Some, but not all, parasitic infections can be detected by testing your blood. Blood tests look for a specific parasite infection; there is no blood test that will look for all parasitic infections.  An ova and parasite test stool test is used to find parasites that cause diarrhea, loose or watery stools, cramping, flatulence and other abdominal illness.
