Along with blood and urine tests,my nephrologist ordered a ultrasound to look at my kidneys for any scarring, size of kidneys etc

When I had AKI they did the blood and urine tests and that’s how they diagnosed it. I was severely dehydrated and ended up in the hospital.

I just Recently found Out I Was Diagnosed With having Kidney injury

I'm also on farxiga 10mg to keep my glucose from reabsorbing thru my blood,and existing thru my urine,I have a question though my creatinine level is 1.76 mg/ dl is that high

How do they diagnose kidney injury ?
