Azotemia is a medical condition characterized by elevated levels of nitrogen-containing compounds in the blood, particularly urea, creatinine, and other waste products. It occurs when the kidneys fail to filter waste products efficiently. This condition can be prerenal (due to decreased blood flow), renal (kidney damage), or postrenal (urinary tract obstruction).
