Ova and Parasite Test
Ova and Parasite Test
An Ova and Parasite test is also known as a ‘stool test’. It is a lab investigation that checks a sample of your stool to detect the presence of parasites or their eggs (ova).
Preparation for the Ova and Parasite Test
You may need to provide a sample of your stool (faeces) for the test. The sample needs to be collected in the container or bag that the laboratory has given you. If you do not follow the instructions for the collection, there is a risk that the test results may be incorrect.
You may be asked to avoid taking certain medications prior to the test as some of these drugs may interfere with the test results. Ask the doctor whether you need to stop taking any of the drugs you are currently prescribed before having the Ova and Parasite test.

During the test the laboratory technician will examine the sample of your stool using various staining procedures and microscopic examination. In some cases additional tests may also be carried out.
