Profitez des bons moments.

It seems like years ago when France showed an interest in IGRAs,

blood assays could replace TST for antibiotherapy

Later on Madhukar Pai reported that for some situations in France

an IGRA test may replace TST

Roll on 2011 and Madhukar Pai is more clear ie for contact investigations, for HIV patients, those on TNF-a inhibitors, the screening of immigrants and for serial testing of HCWs, France recommends IGRA alone.
