Betas? If it is "high beta globulins" on a serum protein electrophoresis, this means nothing in the absence of a meaningful history and physical exam. If it is "beta lipoprotein", this is an old name on the old lipid profile for LDL / low density lipoprotein / bad cholesterol.
More info. This is a very nebulous question that is very difficult to answer. At the very least, info about the specific blood test would be helpful.
