If you list both cytocentrifuge speed and osmolality specimen in a single statement, which would be correct?

Explanation:
Cytocentrifugation needs a moderate speed to concentrate cells onto the slide without damaging them. A range of about 200–1000 rpm provides enough force to deposit cells while preserving morphology; speeds too low won’t sediment well, and speeds too high can distort or damage cells. For osmolality, serum is the standard specimen because it gives a stable, consistent measure of the blood’s solute concentration, whereas urine can vary widely with hydration and other factors. Putting these together, the correct statement is that the cytocentrifuge should run at 200–1000 rpm and the osmolality specimen is serum.
