Test (four hours) started at 8am, had to fast from 10pm the night before.

Exactly as Sunshine185 said.

12 hours. It's usually a 2 hour test though, not 3 (although from you arriving at hospital to actually getting away is likely to be more like 3).

Fast from midnight, test at 8.30. It lasted 2 hours, and once I'd drunk the nasty syrup stuff, was allowed water. Good luck - it wasn't as bad as I'd anticipated, although I had to go straight for food afterwards as I was coming over all odd smile.

I didn't know about this test. How many weeks are you when they do it?
I'm 15 weeks now and still HAVE to eat at 3.00am, 6.30, 8.30, 10.00am to not be sick in the morning. How will I cope with that! Agghhhh!

12 hours.

(Littlemisskiwi, if you are in the UK you are unlikely to be asked to do the test at all unless you have two or more risk factors (and it's normally around 28 weeks if you do do it))

(that's not the case in all areas of the country, THW -- in my PCT they now go straight to 2-hour GTT at 28 weeks if you have 2 or more risk factors, without doing the single blood glucose test)

Thanks all

At least its not for a while then.
ThehedgeWitch - I hope your test comes out OK

I'm with PAL - normal to just do a GTT if there are risk factors. If you've had GD before or have 2 risk factors, then you should be tested around 16 weeks, if you have one risk factor then it's normally around 28 weeks.

My GD was picked up at 17 weeks.

HeathersMummy Tue 23-Sep-08 08:50:54

I've one risk factor - weight blush and I'm being tested at 29 weeks. It's a 2 hour test and I've to fast from 9.30pm, small sips of water only allowed. Test is at 9am - I'll be ready for chewing my arms off by the time it's over grin.
A bit miffed as regular blood tests have always shown a very low blood sugar - I guess it's just another box ticking excerise for the NHS hmm.
