Stool Ova, Cysts and Parasites (Microscopy)
The Stool Ova, Cysts and Parasites (OCP) test is a microscopic examination of a stool sample designed to detect intestinal parasites. This includes identification of parasitic eggs (ova), cysts, trophozoites, and helminths that may infect the gastrointestinal tract. Parasitic infections are a common cause of persistent diarrhoea, abdominal discomfort, bloating, and unexplained gastrointestinal symptoms, particularly following travel or exposure to contaminated food or water. Microscopy remains a valuable diagnostic method for identifying a broad range of intestinal parasites and guiding appropriate treatment.

Clinical Significance
Intestinal parasitic infections may be caused by protozoa such as Giardia lamblia and Entamoeba histolytica, or by helminths including roundworms, hookworms, and tapeworms. Symptoms can range from mild abdominal discomfort to significant diarrhoea, malabsorption, weight loss, and anaemia. Parasitic infections may be more common in individuals who have travelled to endemic regions, consumed untreated water, or experienced exposure through childcare settings or close household contact. Some infections may persist for prolonged periods if not properly diagnosed and treated. Stool microscopy allows direct visual identification of parasite structures. In certain cases, multiple stool samples collected on different days may be recommended to increase diagnostic sensitivity.
Who Might Benefit From This Test?
This test may be appropriate for individuals experiencing persistent diarrhoea, abdominal pain, bloating, or unexplained gastrointestinal symptoms, particularly following recent travel. It may also be indicated in cases of unexplained iron deficiency, weight loss, or eosinophilia on blood testing. Clinicians may request OCP testing when bacterial stool cultures are negative and parasitic infection remains a possibility.
Sample Collection
A stool sample is required for this test. Clear written instructions are provided to ensure correct collection and safe handling. In some cases, repeat sampling over consecutive days may improve detection rates.
Understanding Your Results
A positive result identifies the presence of a specific parasite and enables targeted antimicrobial or antiparasitic treatment. A negative result reduces the likelihood of parasitic infection, though repeat testing may be recommended if clinical suspicion remains high. Results are interpreted in conjunction with travel history, symptom duration, and other laboratory findings.
