it is the acute conversion phase...this is when the Ab first appear in blood...the first best test is HIV ELISA followed by a confirmation by Western Blot

ELISA is the initial test in HIV but since the pt may be in the window period the best test would be p24 antigen level since it is the first marker that rises in the blood. take a look at kaplan notes for step 1 and u will find a figure indiacting this
