RTs

RTs is an acronym that appears in several domains and can refer to different concepts depending on context. The most common expansions are radiotherapy in medicine, reverse transcriptase in biology, real-time in computing, and retweet in social media.

In medicine, RT stands for radiotherapy, a cancer treatment that uses high-energy radiation to target malignant cells. The plural RTs may refer to multiple radiotherapy sessions, treatment courses, or different radiotherapy modalities offered at a facility. In biology, RT stands for reverse transcriptase, an enzyme that converts RNA into DNA. RTs can denote multiple reverse transcriptases used in experiments or the process of reverse transcription itself when describing protocols such as RT-PCR. In computing, RT signifies real-time, describing systems and processing that occur within strict time constraints. RTs can refer to real-time systems or real-time processing capabilities. In social media, RT stands for retweet, the act of sharing another user’s post. RTs therefore indicate multiple retweets of a post.

Because RTs is highly context-dependent, the intended meaning is usually clarified by the surrounding domain or by expanding the acronym on first use. Without such context, RTs can refer to several distinct concepts in health care, molecular biology, computing, or online communication.
