But, it is not the best test if one is possibly exposed. We now send HIV genetic tests which can be positive by day 21 post expos. ...Read more

Testing these is obvious by covering one eye and seeing if the doubling ends. Refinements of this can determine the muscles involved. Less common is doubling in one eye from defects in the lens or retina. ...Read more
