Background: Platelets are more difficult to count compared to other blood cells. Platelet counting is a significant tool used in clinical investigation to prevent bleeding complications. There is a general agreement that automation bring precision and accuracy for platelet counts in healthy individuals. Automation of platelet counting has been embraced in most part of the world, particularly in more developed countries. However, manual platelet counting & estimation is still being done by skilled medical technologist to generate platelet results in most developing countries like ours. The method of platelet counting in thrombocytopenic patients is still controversial. Aims: To compare if there is significant difference between automated and manual platelet counts of adult patients with thrombocytopenia at the clinical laboratory of Saint Paul Hospital Iloilo City, Philippines. Methods: This is a retrospective‐analytical study of 384 samples of complete blood count (CBC) results with thrombocytopenia that contain both automated and manual platelet count values. Results: Out of the 384 adult patients with thrombocytopenia, there was an approximately 1:1 ratio based on sex. Thrombocytopenia was most common between 6 th to 8 th decades of life affecting 36% of patients. The mean of the automated platelet levels was approximately 76 × 10 9 /L with the standard deviation of 45; while the manual platelet count results was 170 × 10 9 /L with the standard deviation of 99. Among adult patients with thrombocytopenia, there was a significant difference between manual and automated platelet count results with p value < 0.05). Summary/Conclusion: Thrombocytopenia affect both male and female sex equally. The higher the age group, the higher is the incidence of thrombocytopenia. Manual platelet counts are highly variable compared to the automated values. There was a significant difference between manual and automated platelet count results.
