Quantitative Reverse Transcription PCR (qRT-PCR) is a laboratory technique used for measuring the amount of a specific RNA. It combines reverse transcription of RNA into DNA and subsequent amplification of specific DNA targets using Polymerase Chain Reaction (PCR). The "quantitative" aspect refers to the ability to measure the amount of starting material, making it an invaluable tool in epidemiology for monitoring disease outbreaks and studying gene expression.
