Comparing analyzer and Fonio method platelet counts in severe thrombocytosis. Manual recount features and reasons for result discrepancies.
❗ Returning to the question of platelet count using the Fonio method.
✅ The analyzer reports a platelet level in the patient’s blood: PLT - 1277 thousand/µL.
✅ But using the Fonio method, my platelet level came out to 1623 thousand/µL, what about yours? (Erythrocytes, RBC - 4.15 million/µL). Microscopy images below.
❓Which result is true, the analyzer’s or the manual method’s?
🙏 The case was kindly shared by clinical laboratory diagnostics physician Alexey Burmaga from Novosibirsk.
