Anyone know anything about creatinine

[Nogodsnomasters]

Hi,

Recently found out I only have one kidney so was sent to the renal dept of the hospital to have functions tested. This is the only one of the urine tests that came back out of range, everything else was normal range or negative in terms of urine. The creatinine is low, does anyone know what this means or indicates? I haven't heard anything from the hospital yet.

Thanks

Look up effective glomerular filtration rate which explains how well your kidneys work. That might explain it a bit.

They've also just sent these and this one is a bit low too.
