7.2.3. Estimated RBC in laser
The couette volume uses 1 milliliter resulting in 100 / 5 = 20 * 10
6
RBC in the couette system
The suspension volume in the laser beam = 0,5 microliter
The diffraction pattern uses (20 * 10
6
/ 1000) * 0,5 = 20.000 RBC
7.2.4. Oxygenscan whole blood volume calculation
Measure RBC level CBC on a Cell Counter.
250/RBC = xx µL blood in 5 ml Oxy ISO
RBC in 10
