Frequently Asked Questions1. Which doctor should I consult for azotemia?

2. What is the average life expectancy of patients on dialysis?
3. Which substances accumulate in the blood in azotemia?
These include nitrogen waste products such as urea and creatinine.
4. Can azotemia be caused by dehydration?
5. At what blood creatinine level should dialysis be started?

6. What is FENa?
Fractional excretion of sodium (FENa) is the amount of salt (sodium) excreted through urine relative to the amount filtered and reabsorbed by the kidney. It is not a test but a calculation based on sodium and creatinine levels in the blood and urine. FENa values less than 1% indicate decreased blood flow to the kidney, which can happen with kidney damage during dehydration or heart failure. FENa values greater than 1% suggests damage intrinsic to the kidney itself.
