What term is used for the measurement of blood glucose after fasting?

The measurement of blood glucose after fasting is referred to as Fasting Blood Sugar (FBS). This test is conducted after an individual has not eaten for at least 8 hours, allowing for a clear indication of baseline glucose levels in the bloodstream without the influence of food intake. It is a critical diagnostic tool used to assess how well the body manages glucose and can help identify conditions such as diabetes or prediabetes.

The focus of this test on fasting levels gives healthcare providers valuable insights into metabolic functions and insulin responses without external factors that could alter glucose levels. The use of the term "fasting" directly emphasizes the need for a specific pre-test condition that distinguishes it from other blood glucose measurement types.
