Dr D has a thing for working out and it has been a long term thing. When you are in your forties and workout 3-5 days a week, you present complexity to your doctor. I have been rocking a serum Creatinine of 1.5 for a few years now. Creatinine is a test of kidney function. The top end of “normal” is usually about 1.2 to 1.3.
What they don’t tell you when you go to the doctor is that serum Creatinine as a test is not universally accepted. In men with larger than “normal” muscle mass it might be elevated. In sick older individuals with kidney failure it is usually elevated. So when it is elevated, are you sick?
So I was changing between health plans and I had a mini work-up for the Creatinine issue. A Renal ultrasound was normal. Then I got to collect my urine for 24 hours. Test results indicate that my kidney might work too well filtering at a higher than normal rate. So what does this mean? Apparently this is not uncommon in men with larger than “normal” muscular mass.
Not all elevated medical tests are meaningful. Test results need to be taken in context.
