Your Pet's Sodium:Potassium Ratio
Na:K In Your Pet’s Blood
Veterinarians ask for this test or pencil the calculations themselves when they are suspicious that your dog might have Addison’s disease. The Na:K ratio is calculated from your pet’s blood sodium level divided by its blood potassium level (We like to see that ratio between 27 and 40:1) . Because Addison’s disease can deplete your dog’s sodium and elevate its blood potassium, ratios that begin with a number lower than 27 might mean that an ACTH test for Addison’s disease is in order.
Reasons Why Your Pet's Na:K ratio might be low :
Not all pets with a low sodium:potassium ratio have Addison’s disease.
Sustained diarrhea, or the inability to urinate (as in a ruptured urinary bladder) can also lower your pet's Na:K ratio.
Akita dogs can also have low ratios for reasons that are not understood.
Repeated removal of pooled abdominal or chest fluids and whipworm infections are also capable of decreasing Na:K ratios.
The same cautions I gave about laboratory-produced false reading for sodium and potassium apply to your pet’s Na:K ratio as well. The same causes I gave for low blood sodium or high blood potassium will drive down the Na:K ratio. The reverse is also true.
