Detecting Low-Yield Target Fungal DNA from Bronchoalveolar Lavage Fluid: Sensitivity Limits of Conventional vs. Quantitative PCR

Introduction 0.5 ng/µL of DNA is detectable and can yield a positive result by PCR. In modern molecular diagnostics, PCR is incredibly sensitive. While 0.5 ng/µL might seem like a low concentration on a spectrophotometer (like a NanoDrop), it is actually a substantial amount of …

SARS-COV-2 Antigen Test Strong Positive-Upper while weak positive -lower test device

Introduction SARS-CoV-2 antigen tests, also known as rapid antigen tests or rapid diagnostic tests (RDTs), are diagnostic tests designed to detect specific proteins or antigens from the SARS-CoV-2 virus, which is responsible for the COVID-19 disease. These tests are used to quickly identify active COVID-19 …
