Molecular Panel Evaluation for Diagnosis of Infections of the Central Nervosous System

Infections involving the central nervous system (CNS), such as meningitis/encephalitis (ME), are serious clinical conditions associated with high morbidity and mortality rates, as well as significant long-term consequences. ME can be caused by a wide variety of pathogenic agents. Clinical symptoms may vary and it has been shown that early identification of the pathogens causing ME allows for timely and appropriate treatment, thus reducing permanent neurological damage. The multiparameter panel "QIAstat-Dx®Meningitis/Encephalitis" can detect in one hour on a sample of 15 bacterial, viral and fungal pathogens. In the diagnostic routine, Real-time PCR takes an average of 3 hours and culture examination 2 days. In addition, compared to other comparable rapid molecular systems, the "QIAstat-Dx" platform has the ability to generate a cycle-related threshold value (Ct) for the targets detected. This value may have a correlation with the viral load and thus provide in a short time not only the result of positivity, but also an indication of the amount of virus present. Other commercially available multiparameter molecular tests provide only qualitative data.
