What are the blood tests to detect worms?

Blood tests used to detect parasitic worm infections include the eosinophil count, which measures the level of eosinophils (a type of white blood cell that often increases in response to parasitic infections). Specific serological tests can also detect antibodies or antigens related to certain worms, such as those causing schistosomiasis or filariasis. Additionally, a complete blood count (CBC) may reveal anemia or other changes indicative of a parasitic infection. However, stool tests are more commonly used for detecting intestinal worms.
