Definitive diagnosis relies on the detection of serum anti-platelet antibodies but this test is not widely available.

Other tests may also be used to exclude potential infectious causes of thrombocytopaenia such as ''[[Ehrlichia platys]]'' and ''Anaplasma phagocytophilum''.

Faecal occult blood tests represent an unreliable way of detecting gastro-intestinal haemorrhage in cases of mild melaena. The animal must be deprived of meat, bismuth subsalicylate and ferrous sulphate for 3 days before the faecal samples are taken for analysis.

Similarly to IMHA, mortality is most likely in the initial stages of the disease and the mortality rate is approximately 30% in this period. Beyond this, the majority of animals recover well although they usually require tapered immunosuppressive treatment for roughly six months to completely control the disease. Initial responses to treatment are relatively quick, so if no increase in platelet number is seen within 1 week of initiating treatment, investigate further for an underlying cause which requires treatment.
