Patient's question:
My nine-month-old son had a fever, a viral cold with ulcers in his throat, and was hospitalized for six days. When he was discharged, a blood test showed platelets at 500. The next day, a follow-up test revealed 545. The doctor suspected "Kawasaki disease," but he had no symptoms of it. I don't know what the cause is, and I'm almost dying of anxiety. I hope for an answer. Thank you!Doctor's answer:
When suffering from a cold and fever, platelet counts may increase. It is recommended to follow up after treatment. Essential thrombocythemia generally does not affect health, but excessive platelet counts may lead to thrombosis. However, most cases are long-term and stable. Therefore, when platelet counts are excessively high, typically around 700-800, medication treatment can be considered. The relevant medications may have some impact on a child's growth and development, so it should be considered cautiously. Machine errors and blood concentration can also cause elevated test results.
