Key result
PCR improves rapid and accurate diagnosis of CNS infections to avoid unnecessary invasive investigations.
Why the study?
PCR has improved diagnosis and understanding of CNS diseases by detecting minute amounts of DNA or RNA, but its role in diagnosis and management across CNS infections and other diseases requires synthesis.
Does polymerase chain reaction (PCR) improve the diagnosis and management of central nervous system infections?
Does polymerase chain reaction (PCR) improve the diagnosis and management of central nervous system infections?
PCR is a valuable tool for the rapid and accurate diagnosis of CNS infections, enabling appropriate treatment and avoiding unnecessary investigations.
Supports PCR for CNS infection diagnosis; leaves open prospective trials on outcomes before practice change.
Polymerase chain reaction (PCR) is a broadly applied laboratory test for the diagnosis of a wide variety of central nervous system (CNS) diseases, including genetic and autoimmune diseases, malignant neoplasms, and infections. With its ability to detect minute amounts of DNA or RNA contained in tissues or fluids, PCR has improved the rapidity and accuracy of diagnosis, enhanced understanding of pathogenesis, and helped identify infectious causes for diseases previously considered idiopathic. In addition, PCR can be performed on a variety of tissues preserved in different ways--even archival specimens can be used to provide important epidemiological information. By making quick and precise diagnoses, appropriate treatments can be instituted, and unnecessary or invasive investigations can be avoided.

DeBiasi et al. (1999) conducted a review in Central nervous system (CNS) diseases and infections. Polymerase chain reaction (PCR) was evaluated. Polymerase chain reaction (PCR) improves the rapidity and accuracy of diagnosing central nervous system diseases, enabling appropriate treatments and avoiding unnecessary invasive investigations.
