A member asked:

One urinalysis showed rbc none seen and another one months later said 0-3 both normal why are they different?

A doctor has provided 1 answer

Within normal limits: These are within normal limits because during activities, there is non-specific trauma on regular movements like walking and sitting and sometimes a red cell can even get filtered through the kidneys normally, so the urinalysis allows for this. That's one of the reasons why there are normal ranges.
