These tests are used to look for some parasitic diseases that may cause swelling of internal organs or abnormal scarring. CDC is a reference lab for the 50 states. This means that CDC cannot accept specimens unless they are sent by your state health lab. It is best to send stool specimens to a lab with experience, such as the local, county, or state health lab, a commercial lab, or a hospital lab. If you receive a negative lab report, your physician may choose to send another sample to a different lab for confirmation.
Blood testing is done by a variety of labs.
Labs throughout the United States are qualified to diagnose parasitic infections.
