Kidney function level of 30.....

[rupert the dog]

Is this bad? Doc seems to think it should be better, but could be worse - anyone out there got experience of this? Thanks

Which measurement is this on?

I had some problems last year with my Creatinine levels - went up to 190-200 after I had severe food poisoning - normal was 90-120

After this I was referred to a Nephrologist, and had some kideney function test - lowest I went on this was 50%
