I just had a recent (March 2013) urinalysis (peed in a cup) and all the results came back negative but there was a note that read: there's a little bit of blood and white blood cells in your urine, we'll test again the next time you come in to the office.
The last time this happened was December 2010 where I also had a little bit of blood, but nothing about white blood cells. (That is the distance between each test, I didn't have any in between)
I'm not nervous or anything like that. I don't have any physical symptoms that I can feel or see for UTI or kidney stones, but I suppose it's possible to have a small stone or also a UTI with some less obvious symptoms.
I'm not sexually active, in that I don't have partners (just me, myself, and I) and my blood work over the years has always been good to go.
I drink a lot of water, take vitamins, and live a pretty healthy life style.
I'm posting this to see if anyone has had similar results and or knowledge of this.
