azotemia vs. uremia

azotemia vs. uremia: What's the difference?

Azotemia is a precursor of uremia, and both are conditions that result from improper kidney function. Azotemia is a state of abnormally high nitrogenous waste products in the blood, which are one of the substances usually filtered out into urine by the kidneys. Uremia typically comes alongside severe kidney failure and involves high concentrations of urea in the blood as well as other symptoms.
