Second 1h glucola?

I had my glucola test a few weeks ago which came out within good range. During todays visit, they found glucose in my urine and they finger poked me 3 times. Once the reading came out to 201, and then we got an error message the other two times so the doctor wanted me to do another glucola test? Is that normal, has anyone had to do the same? The nurse tried to explain but not very well, i guess they want to sew how my body handles the sugar but why would they want to load me up with even MORE sugar when (if accurate) the first reading was so high?
