The Urine Sulfosalicylic Acid Test For Protein = The SSA Test

These days, the urine microalbinuria test or the urine P:Cr ratio are the preferred tests most veterinarians choose to screen dogs and cats for the early signs of kidney problems. All three tests detect blood protein abnormally leaking into your pet's urine through damaged kidneys.

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



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.
