Urinalysis reads no RBC but trace blood. Not understanding how can you have trace blood but no red blood cells & what does that mean?

In brief: Other things..

The test that is looking for "blood" detects things other than just blood - for instance, myoglobin, which is a breakdown product from cells and muscle.
That is why if you test "positive" for blood, you have to look under a microscope and see if there are red blood cells present . Other tests can then get more specific into the other reasons "trace blood" may appear on the dip.

In brief: ? myoglobulinuria

Absence of rbc can be found in muscle breakdown or rhadomylosis with positive.
However the trace blood may not be significant. However if you are on statins and fibrates or exercise excessively you may have your doctor consider checking your CPK . Drink plenty of water.
