Viral serologies can be really confusing. But, these make really good boards questions for those of us in acute care medicine. In this Twitter post, @POCUSmedicine shares a really nice infographic about Hepatitis B serologies. While the top left corner is specific to HBV, the general pattern of interpreting serology results is true of all viral serologies. I learned a mnemonic to help remember this when I was studying for boards…IgM = iMMediate, as in active infection is present; IgG = Gone, as in previous exposure.
