ATN |
Another example of toxic ATN is shown below. Skeletal muscle injury may trigger rhabdomyolysis that can be detected by urine dipstick analysis as positive blood, but no red blood cells on urine microscopic examination. This is explained by the presence of myoglobin, which gives the urine a dark brown appearance. Myoglobin is protein, accounting for the 1+ dipstick measurement for protein. With rhabdomyolysis, the serum creatine kinase will be elevated. |
