A member asked:

Will holding your breath for over a minute during your cbc change the results?

A doctor has provided 1 answer

No.: Try it and see. This will certainly influence some lab tests, but the CBC is just a measure of the number of cells in your blood none of which changes in any significant way over short spans of time or with changes in respiration.
