Hey جدة — let's clarify this. The factor of 10,000 is a multiplication factor in the RBC count formula, not an addition. It is derived from the dilution of the blood sample and the volume of the counting chamber. Here's how it works: Step 1: Understand the standard calculation. The general formula for cell count using a hemocytometer is: RBC count = Number of cells counted × Dilution FactorVolume of counted area (in mm^3) Step 2: Apply typical values for RBC counting. • A common dilution for RBCs is 1:200. So, the Dilution Factor is 200. • When counting RBCs, it's standard to count the cells in 5 small squares within the central large square of the hemocytometer. Each small square has a volume of 0.004 mm^3 (depth of 0.1 mm and area of 0.04 mm^2). • Therefore, the total Volume of counted area for 5 small squares is 5 × 0.004 mm^3 = 0.02 mm^3. Step 3: Substitute these values into the formula. RBC count = Number of cells counted × 2000.02 mm^3 RBC count = Number of cells counted × (200)/(0.02) RBC count = Number of cells counted × 10,000 So, you multiply the number of RBCs counted by 10,000 to get the final RBC count (typically in cells/ or cells/mm^3). The formula for calculating the RBC count is the same for both males and females; however, their normal reference ranges for RBC counts differ. The correct application is to: Multiply by 10,000 One more to go today! Send it over.
