Customer Question

I went for the 1 hr. glucose test. I am 27 weeks pregnant. My number came back as 135 and 135 is the cut off. Should I be going for the 3 hr. test?

Most of the time, a normal result for the glucose screening test is a blood sugar that is equal to or less than 140mg/dL 1 hour after drinking the glucose solution. I'm not sure why your lab has 135 as the cut off.

most likely you don't need the 3 hour test at this point.

but your doctor will continue to monitor your weight and your glucose levels during pregnancy.

let me know if you have other questions.
