I am happy for you Joy. MELD scoring is really only relevant for patients with cirrhosis.
Your creatinine represents a balance between muscle breakdown (usually pretty constant and releases creatinine) and kidney function washing the creatinine out.
Your creatinine is absolutely fine, and nothing to worry about.
When kidneys start to fail creatinine rises. In round numbers a creatinine of:
- 80 represents 100% renal function
- 160 represents 50% renal function
- 320 represents 25% renal function
- 640 represent 12% renal function, and
- 1280 means only 6% renal function
People go pretty well with only 10% renal function, but need dialysis if their renal function falls below this level.
There are many things that can increase muscle breakdown and thus the quantity of creatinine that needs to be excreted by the kidneys.
Eating more meat due to a better appetite or doing more exercise (causing a small increase in muscle breakdown) are quite possibly the reason in you because your creatinine was unusually low to start with, so either you have kick ass kidneys that work much better than the average person, or your meat intake or base level muscle breakdown was lower than usual.
