A study identified of 23 patients with such findings and compared them with 10 patients with positive antemortem blood cultures for Candida, but negative postmortem heart blood cultures. The results indicate that candidaemia—whether at autopsy heart blood culture or by antemortem blood culture—is an insensitive but highly specific indicator of disseminated candidiasis (Journal of Clinical Pathology 2010;63:337-40, doi:10.1136/jcp.2009.070607).

As “e-patients” grow in number worldwide, is there a safer way for consumers to glean good information?
