Implication

Randomized trial evaluates detection of platelet antibodies in dogs with immune thrombocytopenia, suggesting improved diagnostics.

Key Points

The study aimed to develop control reagents for the characterization of platelet surface-associated immunoglobulin in flow cytometric assays for dogs with ITP.
Silica microspheres were coated with canine IgG and IgM for assay use.
Blood samples from 33 dogs (7 healthy, 26 with thrombocytopenia) were assessed for PSAIg reactivity.
Assay evaluations included sample stability and reactivity of anti-canine immunoglobulin reagents.
Sample stability confirmed for 48 hours; positive control microspheres remained fluorescent over 2 years.
Median PSAIgG levels of thrombocytopenic dogs were significantly higher (18.4% primary, 34.1% secondary) compared to controls (3.8%, P < .05).
Rabbit anti-dog IgG consistently recognized canine IgG better than goat origin antibodies.
