What is the function of an antiglycolytic agent?

An antiglycolytic agent serves the primary function of preserving glucose in collected blood samples. This is essential because glycolysis, a metabolic process occurring in red blood cells, can lead to the breakdown of glucose into pyruvate, thus resulting in lower glucose levels in the sample over time. To maintain the integrity of glucose measurements, antiglycolytic agents inhibit this process and help preserve glucose levels for accurate laboratory analysis.

In the context of blood collection and testing, it is crucial to ensure that the glucose levels remain stable and reflect the true state of the patient's condition at the time of collection. By using antiglycolytic agents, phlebotomy technicians can help prevent significant changes in glucose concentration, enabling reliable test results.
