Using the formula for plasma volume determination, what is the calculated plasma volume in milliliters if the net standard count is 839,621 cpm, the standard dilution factor is 15, and the net plasma counts are 2,528 cpm/mL?

To calculate plasma volume, you can use the formula derived from the standard dilution method. The formula is given by:

Plasma Volume (mL) = (Net Standard Count / (Net Plasma Count per mL * Standard Dilution Factor))

In this case, the net standard count is 839,621 counts per minute (cpm), the net plasma counts are 2,528 cpm/mL, and the standard dilution factor is 15.

Plugging the values into the formula, you perform the following calculations:

1. Multiply the net plasma counts by the standard dilution factor:

2,528 cpm/mL * 15 = 37,920 cpm

2. Then, divide the net standard count by this product to find the plasma volume:

Plasma Volume = 839,621 cpm / 37,920 cpm = 22.13 mL (after calculating).

3. Now, to find the correct plasma volume in milliliters, we need to make sure we align our units correctly. Since we've realized a misinterpretation in conversion or significant figures in the earlier calculation, we arrived at a result that can indeed lead to different values. But refining this check generally indicates robustness when re
