Hey,

As a French I can tell you that there is no blood testing or any health related tests that will be done if your friend wants to migrate here.

French citizens do not pay for their HIV meds. If your friend migrates to France legally, and has valid work/asilum visa, it will grants him social security, and so, free hiv meds.

FYI the price of combivir in France (Lamivudine/Zidovudine original drug) is €295, its generic drug (unbranded) costs €160.
Original Efavirenz costs €315, its generic drug costs €139.

Hope this helps, don't hesitate if you have any other questions.
