The Urine Sulfosalicylic Acid Test For Protein = The SSA Test

The SSA test is an older alternative method of detecting when abnormally high amounts of albumen protein is present in your pet’s urine. Healthy kidneys do not let blood albumin escape.

These days, the urine microalbinuria test , the urine P:Cr ratio, and your dog and cat’s BUN and Creatinine blood levels are the tests most veterinarians would choose when screening your dog or cat for evidence of kidney disease. The SSA and the first two other tests detect situation in which blood proteins are abnormally leaking into your pet’s urine because of damaged kidney filters. The SDMA test is a current favorite as well. Read about the SDMA test here and that SDMA test’s significance here .   

The SSA test was once thought to be a more precise way to measure that protein leakage than visually comparing the color change on veterinary office urine dipsticks to the chart that is printed on the side of the bottle. (ref)

More recent date suggests that the SSA test is no better than the dipstick color (colorimetric) comparison method.

Since transient situations such as high fever or extreme exertion can also account for temporary protein-positive urine. Consider having these tests repeated if either situation preceded these tests.
