If the dilution is 1:100, and the average platelet count from both sides of the hemacytometer counting chamber in 2 mm2 is 68, what is the calculated platelet count? A. 680,000/mm3 B. 6,800/mm3 C. 68,000/mm3 D. 680/mm3 E. 34,000/mm3 - ANSWER C; A simple way to calculate platelet counts on the hemacytometer is to multiply the average platelet count between the two sides of the chamber by 1,000. In this case 68 x 1,000 = 68,000 platelets. The longer derivation is as follows: The standard ...
