Hi all! I have a quick question...is it possible for blood and wbc in urine to not show up on a dipstick but to show up during a urinalysis? My cat hasn't been feeling well so I got a urine sample yesterday, it was dark brown/amber. I did a dipstick test on it and everything was normal except a bit of protein. So I took the same sample to the vet, they did a urinalysis yesterday which showed blood and wbc. They put her on amoxi drops for a U.T.I. Also, the dipstick didn't show any bilirubin either, which I thought might lead to the dark color, and I'm sure it didn't show up with the urinalysis since the vet didn't mention it. Why would blood and wbc not show on a dipstick but show on a urinalysis? Any help is appreciated!
