About this test
Ringworm is a skin infection caused by a fungus, not a worm. In cows and buffaloes it often shows as round, grey-white, crusty patches without hair, commonly on the head, around the eyes and on the neck. Young stock kept close together are affected most. For this test, hairs and skin scrapings from the edge of a patch are soaked in KOH (potassium hydroxide), a liquid that clears away skin and hair material so fungal spores and hyphae (thread-like strands) show up under the microscope. If none are seen, your vet may ask for a fungal culture. A registered veterinarian interprets the result along with the look of the patches.
How to prepare
Do not put any cream, oil or other application on the patches before the sample is taken, and wear gloves if you touch them. 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.
