what happens if you fail a 3 hour glucose test?

Annaliesa
I am now in the process of taking my 3 hour glucose test, and wondered what happens if you were to fail it? I failed my 1 hour test by 5 points, according to my test results but wondered what happens if I fail this test? First time mom and feeling clueless! TIA!
Here is my results from the 1 hour test.
