Coccidia Oocyst Count (OPG)
A coccidia oocyst count (OPG) counts the egg-like stages of coccidia in each gram of faeces. It is mostly used for calves, puppies and kittens with diarrhoea, and helps your vet judge how heavy the infection is.

About this test
Coccidia are tiny gut parasites that are passed in faeces as oocysts, which are tough, egg-like stages. Young animals in crowded, damp or dirty housing pick them up easily, and stress such as weaning or travel can make illness worse. The illness, called coccidiosis, may cause watery or bloody diarrhoea, straining and weight loss. This test counts the oocysts in a measured amount of faeces, so the result shows how many are being passed. The count is only part of the picture, because diarrhoea can start before many oocysts appear and some kinds of coccidia cause little harm. A registered veterinarian reads the count with the animal's age and signs.
How to prepare
Collect fresh faeces into a clean closed container, from the rectum for calves if your vet can, and label it with the animal's name and age. The lab confirms the method, sample needs and reporting time when you book.

Before you book this test
Why this notice: so you know, before you book, how a test is done, what its limits are and who is responsible.
- Where it is tested. Some tests are done wholly or partly by an independent partner laboratory. The lab tells you before booking if this test is sent out, and the report names the laboratory that did it.
- What a result can and cannot tell you. No test is right every time. A normal result does not rule out every disease, and an abnormal result does not prove one. A registered veterinarian should read the report with the animal’s signs and history before any treatment is started, changed or stopped.
- The sample. A sample that is clotted, too small, wrongly labelled, leaking or too old may be rejected or reported with a note, and the lab may ask for a fresh one.
- Reporting time. Confirmed when you book. Times are estimates, not guarantees, and the lab confirms the time when you book.
- Emergencies. A booking or a pending report must not delay urgent care. If an animal has collapsed, struggles to breathe, has fits or bleeds heavily, call a veterinarian at once.
