The Two-Hour Glucose Tolerance Test: Highlights, Lowlights and Vern

Because I’m a spectacular failure and soared well over the threshold for my one-hour Glucose Challenge Test (GCT) last week, I went back to the lab today for a second screening for gestational diabetes — the dreaded two-hour Glucose Tolerance Test (GTT).

As predicted, to pass the time, I once again live-blogged the entire thing.

But first, a little background.

WHY THE TWO TESTS?

In Canada, there are two screens for gestational diabetes, according to Diabetes Canada: the Glucose Challenge Test (GCT) and the Glucose Tolerance Test (GTT).

The GCT involves drinking a sugary drink containing 50 g of glucose, and having your blood drawn an hour later to check your blood sugar level. The idea is to see how efficiently your body processes sugar.  If the reading is too high, you have to go back for a two-hour Glucose Tolerance Test (GTT), which involves more blood draws and a higher concentration glucose drink, to see whether you really do have gestational diabetes.

Okay, let’s do this.

8:00am: After 12 hours of fasting, my blood was just taken to establish a baseline. This is the first of three blood draws I will have this morning. I feel lightheaded already and I haven’t even choked down the glucose drink. 75 g this time, vs 50 g last time.

Cheers.

8:30am: Since I’m going to be here a while, I wasted no time in making new friends.

Meet Vern.

Vern is a year-and-a-half-old yellow lab whose likes include wandering around sniffing everyone’s crotch, whining impatiently when he’s not being directly spoken to, and delicious pocket treats generously dispensed by his human, James. I’m not sure of the specific medical reason James has for needing a service dog like Vern, but I kind of want the same diagnosis because Vern is a really, really good boy. If he wasn’t so obviously serving a legitimate medical purpose, I would be currently orchestrating an elaborate plan to kidnap him when James gets up to get his blood drawn. We’d start a new life together, Vern and I, full of frolic and fancy. Take me out of this place, Vern. Take me far away.

9:00am: It’s time for my second draw to see how I’m reacting to the early morning sugar dump into my bloodstream. If last week is any indication, my guess is not well. Vern, send me all your strength.

Wait for me on the other side, pal.

9:15am: My favourite lab tech — a no-nonsense Jamaican hurricane named Karen — is here today, and we had a good chat as she expertly stuck a needle into my bruised arm. Shortly before my name was called, an irate eastern European lady sitting across from me began to sass-mouth her and Karen was having NONE OF IT. Her professionalism shone through like the class act that she is, but I swear, she was seconds away from Lab Lady Smackdown 2017 on this horrible woman. Team Karen all the way — I’d ride with her into battle any day of the week. Vern informed me he is also on Team Karen.

9:30am: To everyone’s dismay, Vern has departed the lab, dutifully following his human, James, out the door. No one is more devastated than I am. How will I make the last leg of this journey without you, Vern?

I’m never washing these pants.

9:45am: Janet Jackson is blasting in my earphones. If this woman can dance like it’s her last day on earth and pop out a baby at 50, I can handle a secondary test for gestational diabetes at 33.

10:00am: Karen beckons. It’s time for my third and final blood draw. I’m not sure I want to do this without Vern to come back to. I’m not even sure that I can.

10:30am: It’s over, and now we wait. Special shout-out to Vern, for giving me the support I needed during this difficult time. Full disclosure — today, I’m eating like there’s no tomorrow, because in mere hours, I’ll probably have a diagnosis of gestational diabetes and it’ll be, at the very minimum, a strict diet of vegetables and chicken from now until July. This is unbelievably devastating for reasons I’m not quite ready to acknowledge, so in the meantime, I’m going to savour these Toaster Strudels like I’ve never savoured anything before.

Bon appetit.
