Blood tests shows high gamma globulin & high igg. ifx shows no monoclonal protein & free light chains are within normal range. what does this mean?

It might be a benign: Many benign processed can cause hypergammaglobulinemia, which are benign elevations without a para -protein or m-spike on serum protein electrophoresis(spe)> it all depends on how high is the gammaglobulin level and making sure the liver functions are ok and there is no chronic inflammation(like rheumatoid arthritis, sarcoidosis etc) going on inside the body.
