Your analyzer gave a platelet count of 71×103/mcL. Because this is a low value, you decide to double check the result by scanning a slide and performing a platelet estimate. While scanning on 10x you notice large platelet clumps as you scan the slide. If you were to perform a platelet estimate, would it be accurate? In addition, due to the clumped platelets, would the value given by the analyzer be falsely decreased or falsely increased?
