Trutol Glucose Tolerance Beverages for GTT Testing

Trutol is the standardized glucose drink clinicians and patients reach for when an oral glucose tolerance test (OGTT) is on the schedule. Each bottle delivers a precise, measured dose of glucose so lab results stay consistent and comparable — whether you're screening for gestational diabetes, confirming a diabetes diagnosis, or monitoring impaired glucose tolerance.

The Fisher Scientific Trutol Glucose Tolerance Beverage comes ready to drink in a single 10 oz. bottle, is caffeine-free, and is formulated for the fasting-then-testing protocol most labs follow. Because it arrives premixed, there's no powder to reconstitute and no risk of a mismeasured dose — you get the exact carbohydrate load the test requires, every time.

Two questions come up constantly with these drinks: how much glucose is in a bottle, and does the flavor matter? Trutol is offered in defined glucose amounts to match the load your ordering provider specifies (a fixed grams-of-glucose dose is what makes the result valid). Flavor exists purely to make the drink easier to finish quickly — patients are typically asked to drink it within a set number of minutes, and a chilled bottle goes down far more comfortably than a warm one. Refrigerate before use if your protocol allows.

For labs and OB practices, Trutol is a practical stock item: shelf-stable, individually bottled for grab-and-go dosing, and free of the prep steps that slow down a busy draw station. Patients prescribed a take-home test appreciate the same simplicity.
