My test levels aren't back yet but I'm worried about my creatinine and Bun/cre ratio. Creatinine, serum is low. Range: 0.6-1.4 & I have 0.3. Bun/crea ratio is high. Range: 10.0-23.0 & I have 70.0. They say a high BUN means my kidneys or liver may not be working properly however it also states that if I have a high protein diet (which I do) it can cause these numbers. Any input? I'm a bit worried...
