Babesia species infection (babesiosis) mimics many other conditions, including other chronic infections and a number of autoimmune diseases. If you are experiencing hard-to-diagnose chronic symptoms and have had a recent tick attachment or live in a region endemic for Babesia, you should consider testing for babesiosis. Symptoms can range from mild to a malaria-like illness, characterized by:

  • high fever
  • headache
  • muscles aches
  • loss of appetite
  • nausea
  • fatigue
  • swelling of the liver/spleen
  • anemia
  • other conditions that may require immediate medical attention.

This vector-borne infection is primarily transmitted to humans by Ixodes ticks, but can also be transmitted through blood transfusion.  Clinical presentations may be more severe when co-infected with multiple tick-borne pathogens.

Tests Offered

Babesia/Theileria species PCR Test


The Babesia/Theileria species PCR test is designed to detect all pathogenic Babesia/Theileria species. Positive results are confirmed by DNA sequencing to identify the infecting species. Babesia testing is recommended for occupational screening of animal health professionals and diagnostic testing for symptomatic patients with risk of exposure.
