During the 2-hour OGTT, how many blood draws are typically performed?

• A. 1 time
• B. 2 times
• C. 2 or 3 times (if pregnant)
• D. 4 times

Answer: (C)

The test checks how well the body handles glucose after a fixed amount is taken orally. For a 2-hour OGTT, the usual approach is to take a blood sample while fasting and then again around two hours after drinking the glucose solution to see where the glucose level stands at that two‑hour mark. In pregnant patients, some guidelines include an extra sample at about one hour after the load to better evaluate glucose dynamics, which increases the total number of draws to three. So, two draws are typical, but in pregnancy a three-draw approach is sometimes used. A four-sample schedule would be used for longer tests (such as a 3-hour OGTT), not the standard 2-hour version.
