Why Yale Medicine?
  • Our physicians and staff can offer several tests to accurately identify potential parasites.
  • We partner with researchers at the Yale School of Public Health to address ongoing research into parasitic diseases.
  • Both stool and blood samples can be examined in order to reach an accurate diagnosis for the type of parasite.

A parasite can sound like something out of a science-fiction movie: A foreign creature enters your body, usually through food, water, or an insect bite, causing anything from minor symptoms to life-threatening illness. Though diseases caused by parasites are far more common in underdeveloped countries, which may have unclean water and poor pest control, they still affect millions of Americans each year. At Yale Medicine’s Laboratory Medicine department, these diseases are diagnosed using the most up-to-date testing methods.
