hello i just had a blood test ad urine test today, and got my results already, havnt seen my dr yet however i just received the results by e mail. everything seems normal except Erythrocytes ...2-5 got worried a little, but after reading on wikipedia, they say it could be a result of kidney stones actually, i have kidney stones 2 years ago and i am followed every year buy my urologist. Should I be worried?? i am 50 years old and feel very well except low blood pressure. Thank you
