Question | Answer | Article | |
What test has been performed, and what is the abnormality pictured? | Slide test for autoagglutination. Autoagglutination. |
[[|Link to Article]] | |
What does this abnormality suggest about the etiology of this dog’s anemia? | The presence of autoagglutination, when differentiated from rouleaux formation, suggests that this patient’s anemia is immune-mediated in origin. |

Is a Coombs’ test necessary to confirm the diagnosis? | A positive result in saline slide agglutination negates the need to perform a Coombs’ test. |

How would you treat this patient? | Treatment of IMHA depends on non-specific suppression of the immune system, with glucocorticoids being the mainstay of therapy. In dogs with autoagglutination, aggressive treatment with prednisone (2–4 mg/kg p/o bid) and a cytotoxic drug is warranted from the beginning. Cyclophosphamide (50 mg/m2 p/o 4 days per week) or azathioprine (2 mg/kg p/o daily for 4 days, then every other day) may be used. Cyclosporin A (10 mg/kg p/o bid for 10 days) may be used in patients with intravascular hemolysis. |
