That is my understanding as well. If I recall correctly, to be negative for HBsAg, but positive for anti-HBc (Hep B core IgM, I think) can mean a false positive, recent acute infection, or chronic carrier with unmeasurably low circulating HBsAg. They typically don't look any further, though there certainly are tests (like PCR-based viral DNA assays as well as liver function tests) that can more rigorously establish chronic disease or lack thereof.
