Hi, in every urine test I have done it always shows either trace or small amt. of protein, hemoglobin and leukocyte esterase at times but in all tests no nitrites are found. What could it mean? I am 44 yrs female, 5'1 & weigh 142. I have fibromyalgia, Cardio vasospasm, Hypertension, interstitial cystitis, diverticulosis and possible MS.
