I was told i had low vitamin d, blood trace in my urine and protein in my liver. what are the possibilities and what is most likely?

Interpreting doctors: Hi the 'protein in my liver' part of your question does not make much sense. But, we now know that every human needs to have a good level of vitamin d in our bodies. We do not get much of this from the sun and so it is wise to start and stay on a daily vitamin d. Blood in the urine is usually a sign of a bladder infection. If the bleeding increases or you are a smoker you need further tests.

Low vit D: Is now known to be responsible for a lot of serious disease. It is not just a "bone vitamin" and affects every cell in the body. You need heavy replacement and as soon as the sun is ready for sun bathing start slowly to get a tan. You make your own vit d from the action of sunlight on skin.
