When RBC in urine is said to be high?

High levels of red blood cells (RBCs) in urine, a condition known as hematuria, can indicate various underlying issues, such as urinary tract infections, kidney stones, or more serious conditions like kidney disease or tumors. Generally, more than three RBCs per high-power field in a urine sample is considered elevated. It's essential to consult a healthcare professional for proper diagnosis and treatment if hematuria is detected.
