Cryptosporidiosis is a diarrheal disease caused by infection with Cryptosporidium parasites. This microscopic parasite can cause watery diarrhea, stomach cramps, nausea, and dehydration. Accurate diagnosis requires specialized laboratory testing to detect the parasite in stool samples.
Recommended Test
Ova & Parasites w/Giardia Antigen (Stool)
This comprehensive stool test is designed to detect various parasites, including Cryptosporidium. The test can identify Cryptosporidium ova (eggs) and parasites in the stool, which indicates an active infection. Detection of these microscopic organisms confirms the diagnosis of cryptosporidiosis and helps guide appropriate treatment.

Diagnosing Cryptosporidiosis
Because symptoms of cryptosporidiosis can be similar to other gastrointestinal infections, definitive diagnosis relies on laboratory testing that can detect Cryptosporidium parasites or their components in stool samples. This ensures appropriate treatment and helps prevent transmission to others.
Understanding Test Results
A positive result indicates the presence of Cryptosporidium parasites in the stool, confirming an active infection. Early detection is important for managing symptoms and preventing dehydration, especially in vulnerable populations such as young children, elderly individuals, and those with compromised immune systems.
