Testing your pet's urine for protein, blood, and pH can provide important information about their overall health status.
Protein in the urine, also known as proteinuria, can indicate kidney issues or other systemic conditions.
Blood in the urine can be a sign of urinary tract issues, bladder stones, or kidney stone issues.
Specific Gravity measurements in the urine can also indicate various conditions such as urinary tract issues, kidney stones, and metabolic imbalances. 
Usually, an imbalance of fluids in your urine can be simple things, but can range to much more difficult situations. Detecting these issues early on can lead to timely intervention and treatment, which can significantly improve the outcome for your pet. Therefore, testing your pet's urine for protein, blood, and pH is a good idea to help ensure their health and well-being.
