Look at the blood urea nitrogen, or BUN, and creatinine levels in the blood test. This test is conducted only by a vet. The levels of these substances directly correlate with the severity of kidney disease. When BUN and creatinine levels are increased, this means the kidneys are being progressively damaged and there is a loss of filtering function. This change is irreversible. Normal BUN values range from 10 to 30 and do not vary by cat breed. Normal creatinine values range from 0.3 to 2.1.
Look at the hemoglobin level on the blood test. If the hemoglobin level is decreased, this means that the cat has a condition known is anemia. CRF can result in anemia, because the kidneys are involved in the production of red blood cells and hemoglobin. If the kidneys are failing, there is a drop in hemoglobin. Normal hemoglobin values range from 9.5 to 15.
Look at the potassium levels. CRF can result in low potassium levels, putting the cat at risk for an irregular heart rhythm. The body will attempt to compensate by shifting potassium from the cells to the bloodstream. Thus, even a low-to-normal potassium level can indicate ongoing kidney damage. Normal potassium levels range from 3.7 to 5.8.
How to Interpret CRF Blood Test Results in a Feline
Cats can undergo age or metabolic-related diseases similar to humans. Chronic renal failure, or CRF, is a condition that causes kidney damage and results in the buildup of dangerous toxins. Take your cat to a doctor if you suspect that it is sick or suffering from an insidious condition. Initial CRF symptoms are usually increased thirst or urination. Have electrolyte and metabolic tests done on your cat to help diagnose CRF.
