Plain-English summary
A study found that using amikacin, an antibiotic, in blood samples from healthy cats helped prevent clumping of platelets, which can interfere with accurate blood tests. In samples without amikacin, 56% showed platelet clumps, while only 5% of samples with amikacin did. This means that adding amikacin to the blood collection process could lead to more accurate blood counts without affecting other important blood measurements. This could be particularly useful for veterinarians when performing complete blood counts on cats.

Abstract
INTRODUCTION: Physiologically, feline platelets are more reactive and prone to aggregation, which interferes with platelet counts using automated counters and manual methods. The use of aminoglycoside amikacin in association with EDTA has proven to be efficient in preventing platelet aggregates in cases of pseudo thrombocytopenia (PTP) in people. OBJECTIVES: This study evaluated the efficacy of amikacin in preventing platelet aggregation in EDTA-containing feline blood samples and investigated the possible effects on hematologic measurands. MATERIALS AND METHODS: Blood samples (1.0 mL) collected from 100 healthy cats were stored in two EDTA tubes: 0.5 mL in a microtube containing 10 μL of 250 mg/mL amikacin (EDTA-AMK group) and 0.5 mL in a microtube containing only K2 EDTA 10% (EDTA group). A CBC was executed with an automated impedance blood analyzer, and a microscopic examination of the blood smears was performed. RESULTS: Platelet clumps were observed in 56% of samples from the EDTA group and 5% of samples from the EDTA-AMK group. Platelet counts (PLT), plateletcrit (PCT), and WBC counts were significantly higher (P < .001) in the EDTA-AMK group compared withi the EDTA group. CONCLUSIONS: Amikacin prevents platelet aggregation in feline venous blood samples and does not cause clinically relevant changes in other hematologic measurands. To our knowledge, this is the first report showing the use of amikacin in preventing platelet aggregation in feline blood samples. Based on this study, amikacin could be added to EDTA collection tubes for complete blood counts in cats.
