If neg, then no leuk attack present, or very low grade. So --- leukocytes without infection do appear in urine from interstitial nephritis , usually allergic, or from interstitial cystitis, usually of unknown ...Read more

Many crystals can be caused by kidney stones or food metabolism issues. ...Read more

I took an at home uti test. Twice I was negative both times for Leukocyte and bright pink positive for nitrite.... Does this mean I have a uti??

Yes you most likely : Nitrites are highly sensitive and specific for UTI's. It is unusual that you don't have any or negative leukocytes (WBC's) though. I suggest that you go and visit your physician or local urgent care for a more accurate test to confirm the diagnosis of a UTI and to possibly get a urine culture and sensitivity done. Symptoms of a UTI include frequency, urgency and painful urination. Good Luck! ...Read more
