Brief Answer:
Urine dipstick Results

Detailed Answer:
Hi

We have recently moved away from urine disptick as an accurate measure for blood in the urine. The reason is there is a high probability of false positive results. The true test is urine microscopy which found no blood. The dysmorphic cells are usually cells of the bladder lining that shed from time to time.

I would worry about blood in the urine as the true test for that was negative. Urine dipstick in inaccurate and should not be used.

Why did the lab label it as very mild glomeur disease. The lab didnt no of my other tests: ultrasound, cystocosoy, and kidney function vlood work being all normal. Does the other test being normal dismiss mild glomuer disease? Would the other tests i took have shown mild glomeur dusease if i had that? Finally how can i have blood negative result and dysmorphic cells at the sametine

Brief Answer:
yes and no

Detailed Answer:
Some types of glomerulonephritis can leak dysmorphic red blood cells in urine (hence the dysmorphic component and the label mild glomerular disease). What is reassuring is that intact blood cells are negative. The other tests being normal is great, but does not dismiss the dysmorphic cells. When we see this we typically treat high blood pressure with an ace inhibitor medicine and repeat the urine test in 3 months to see if the presence of dysmorphic cells are there.
