Azotemia

Long Ago it was called uremic poisoning or just kidney failure

Your cat or dog is said to be “Azotemic” when the amount of urea and creatinine in its blood is above normal. The term for the condition azotemia produces is uremia.

 

Conditions That Can Causes Azotemia In Your Pet :

Any condition that decreases the capacity of your dog or cat’s kidneys to move urea and creatinine out of the blood stream and into the urine (reduced glomerular filtration rate = GFR). This can be due to kidney damage (renal causes) or a decrease in the amount of blood passing through the pet’s kidneys (pre-renal causes) like the inefficient circulation that occurs in heart disease or inadequate fluid intake.

When BUN and Creatinine rise significantly in your dog or cat due to kidney disease (renal causes), two-thirds of its kidney’s filtering units, the glomeruli, are not functional.

Complementary Tests :

Urine specific gravity, complete urinalysis, anion gap, blood phosphorus, potassium and magnesium levels, PCV, reticulocyte count, Response to IV fluids, urine specific gravity less diagnostic of kidney disease in cats, after-trauma tests for bladder integrity
