What if you have 2-4 rbc in urine?

Having 2-4 red blood cells (RBCs) in urine, a condition known as hematuria, can indicate a variety of underlying issues, ranging from benign causes like exercise or minor urinary tract infections to more serious conditions such as kidney stones, tumors, or glomerulonephritis. It's important to consult a healthcare professional for further evaluation, including possible urine tests or imaging studies, to determine the cause. While a small number of RBCs might not be concerning, any persistent hematuria should be investigated to rule out serious conditions.
