Following a recent blood draw, my creatinine reading was off the chart 25 mg/dl it had been 1.2. I self cath every 6 hours. Is that sufficient?

Clarification. Are you sure that 25 wasn't the blood urea nitrogen? Bun? Different than the creatinine.
Too high. That seems incorrect. As in, they wrote the wrong number down on that part of your chart. I am no nephrologist, but a creatinine of 25 is easily 3-4x the level of a dead person. It should be rechecked by a reliable lab, and you need to see your doctor immediately.
Lab error. There has been an error somewhere in the lab or transcription. I'm sorry this happened.
