The results are part of blood tests for a business medical for an overseas job. The medical was carried out in Portugal. Test results were
Ac.Anti-HIV 1&2 + Ag (MEIA) - negative
AgHBs (MEIA) - negative
Ac.Anti-HVA, IgM (MEIA) - negative
Ac.AntiHVC (ELISA) - negative
But the test Ac.Anti-HVA.IgG (MEIA) was positive and I want to know if this is something to worry about. What does it mean and should it prevent the patient from working in Middle East?
