What is a Mixed Meal Tolerance Test?
A Mixed Meal Tolerance Test (or MMTT for short) tells doctors how much insulin your body is still making. It involves drinking a special drink called ‘BOOST’ that tastes like a milkshake, and contains protein, fat and carbohydrates. The drink will increase your blood sugar, causing insulin to be released from your beta cells. Over a four hour period after drinking the Boost, eleven blood samples are taken at specific time points. An intravenous catheter (an IV) will be placed in a vein your arm at the start of the procedure through which all blood samples will be obtained. The samples are sent to a lab for analysis.
