What is the procedure for a PPBS test?

A PPBS test involves eating a meal as directed by your doctor, followed by a blood sample collection exactly two hours later. A healthcare provider will draw blood from a vein in your arm, which is then analyzed to measure glucose levels. The two-hour interval allows time for your body to process the carbohydrates in the meal, providing insight into your body’s insulin response. Results are usually available within a few hours or the next day, depending on the lab.
