Albinum 5.1 globulin 1.9 ag ratio 2.7 . the report said 1.9 was low and the ag ratio was high. are these numbers concerning? all other blood work came back normal?

It is difficult to interpret labs taken out of the context of the clinical situation-like what symptoms, if any, are you having? Having said that, these labs results are not concerning. The ratio is high because the globulin is slightly low but a mildly low globulin by itself is not a reason to be concerned. The trend would be informative, is it decreasing or increasing over time?
