Bag 382, sounds like her liver. Occult (or hidden) blood is higher up in the GI tract. It cannot be seen with naked eye must be tested with culture. Bright red blood in stool is lower GI bleed. Because urea is synthesized (or manufactured) in the liver, liver failure causes a reduction of urea in the blood. I would have the vet run some liver enzyme tests on Emily. I know for people its the ALS and ALT enzyme tests that are the hallmark "markers" of liver inflammation or damage. |
