Ketonuria is defined as the presence of ketones in the urine, which can indicate a serious condition such as diabetic ketoacidosis. However, there are several synonyms for this term that can be used interchangeably depending on the context. Some of these include ketonemia, which refers to elevated levels of ketones in the blood, and acetoneuria, which specifically refers to the presence of acetone in the urine. Other alternatives include acetonemia, acetonuria, and beta-hydroxybutyric aciduria, which all describe various ways that ketones can be measured or detected in the body. It is important to understand these terms when discussing the health implications of ketone metabolism.
