Test your diagnostic instincts: Quick-read CNS infection mysteries

When central nervous system (CNS) infections can turn deadly within hours, early diagnosis is essential. But often, these infections begin with vague or overlapping symptoms that obscure a definitive diagnosis.

QIAstat-Dx syndromic testing empowers clinicians to identify pathogens quickly, even when the presentation is misleading.

Explore these short, real-world clinical cases shared by frontline clinicians and laboratory scientists. Each is an interactive mini-mystery – can you solve it before the diagnosis is revealed?

New: QIAstat-Dx sets the benchmark for meningitis testing

The WHO now strongly recommends PCR-based testing for fast pathogen detection in patients with suspected CNS infections ¹.

Our new IVDR-compliant QIAstat-Dx ME Panel aligns with the latest WHO guidelines and offers added value with unique detection of emerging pathogens like S. pyogenes. With some of the broadest coverage available – 16 clinically relevant pathogens, including CMV – it helps you detect more causes at once and get answers in about an hour.

Get the clarity you need to make confident decisions.
