A method for determining the presence of an infection in a liquid sample comprising the steps of: lowering the pH of the liquid sample so as to drive short-chain fatty acids present in the liquid sample, acetic acid in particular, to the gaseous phase; detecting short-chain fatty acids, ammonia and, optionally amine species present as gases in a headspace associated with the liquid sample using a detector which is sensitive to the presence of short-chain fatty acids, ammonia and, optionally, amine species, particularly conductive and semi-conductive polymer sensors; and correlating the presence of detected short-chain fatty acids, ammonia and, optionally, amine species with the presence of the infection.
