    Is this a good or bad sign and what does it mean?

    My urea has always hovered around 3.0 mmol/L (2.5 - 7.0)

    It is now 8.5 mmol/L (2.5 - 7.0)

    Any insight would be most appreciated.

    Do you eat a lot of salt?

    I eat salt to taste.

    Well I know that salt increases urea synthesis. Generally high urea is a good thing. I'm not sure about urea out of reference range however.

    It can be a sign of high muscle catabolism, dehydration, high protein diet, or even kidney issues. I would test cortisol and kidney function, as well as electrolytes and CO2.

    Wouldn't high urea be a good sign, similar to high uric acid? I think it would be a sign of good CO2 production

    It would have to be considered together with other variables like creatinine, electrolytes, cortisol, etc. You can get high urea from eating a high protein diet or getting dehydrated but in general high urea is not looked upon favorably in the medical world especially if some of the other biomarkers of tissue damage are also elevated.

    This is Ray Peat's reply in regards to blood urea being high and outside of the reference range.
