What is PDD by serology (Proventricular dilatation disease) test ?
PDD is an extremely contagious disease. When a PDD case is detected in a farm, the farmer usually loses many birds.
This disease mainly affects large parrots (macaw, cockatoo, Gray parrot).
The infected bird loses weight, although it normally eats, then ends up in a few weeks.
Differences between PDD by serology and by PCR test ?
Genimal had developped 2 differents tests to detect PDD, by PCR and by serology.
- PDD by PCR had the main advantage to be a very fast test (1-3 days, Express option 1 days) and the sample is easy to perform because it consists on a cloacal swab. However this test is accurate only at 70%. So this test should be used when the bird health is endangered and you need very fast result.
- PDD by serology is a longer process (7-15 days) and samples are difficult to collect because we need blood. However this test is 100% accurate.
Type of sample
- Blood in dry tube
