Full origin of PSA →Frequently asked questions
What does PSA mean in a social media post?
It stands for public service announcement and is used, usually half-jokingly, to introduce something the writer thinks everyone should be aware of. It signals "listen up, this is useful" rather than an official notice.
What is a normal PSA level?
Below about 4 nanograms per millilitre has traditionally been treated as normal, but the threshold rises with age and varies between labs. A raised PSA can be caused by infection, an enlarged prostate or recent exercise as well as cancer, so results are always interpreted by a doctor alongside other findings.
What is the difference between a PSA and an advert?
An advert is paid for and promotes a product or brand. A PSA carries information in the public interest, is usually produced by a government body or charity, and broadcasters often carry it free of charge.
