Hi, To find out if you have blood in the urine, we have to look at the urine report. Blood in the urine may be gross hematuria which means many red cells in the urine. Gross hematuria can be seen with our eyes as red urine. There is another type called microscopic hematuria where red cells are seen under the microscope. If red cells or red cells casts are present in the urine along with protein in the urine it means there is a kidney problem especially in a structure called glomerulus. Red cells or Frank blood in the urine may occur more commonly due to stones. It may also be seen with certain infections. Above the age of 40 , we also try to rule out the possibility of kidney or bladder cancer. Certain medicines and certain food items may colour the urine red but in this case the urine report is negative for blood or red cells. A condition called myoglobinuria where the muscles are affected may cause red urine. The first step therefore is to read the urine report. Blood in the urine is usually investigated with an ultrasound initially follower by other tests according to the most likely cause. Should you require further assistance, please post your urinec, blood and other reports here so that I may provide you more information regarding your query. Best regards, DrGeetha
