My a/g ratio says 2.9 is that something to be concerned about? all other ranges are within the normal.30 year female no health issues

Nope.: An isolated abnormal A/G ratio is generally clinically insignificant. Nothing to worry about. From Quest Labs: "The albumin to globulin (A/G) ratio has been used as an index of disease state, however, it is not a specific marker for disease because it does not indicate which specific proteins are altered. The normal A/G ratio is 0.8-2.0. "
