Respiratory syncytial virus (RSV) was detected easiest when using reverse transcription polymerase chain reaction (RT-PCR) tests in a pediatric population.

In a recent study posted to the medRxiv* server, researchers in Germany and Switzerland evaluated 11 commercial reverse transcription-polymerase chain reaction (RT-PCR) kits (A to L) for Monkeypox ...

RT-PCR tests are not perfect, Alland said. “After the first week of infection, there is a decline in virus shedding in the respiratory tract, where tests can become falsely negative,” he said.
