When Reid, 20, heads to the bench during a game the club's medical services manager Andrew McKenzie will issue a simple finger-prick blood test before directing the young Queenslander for a walk along the boundary.
By the time he returns, McKenzie will know Reid's sugar levels and will advise him on the next course of action.
"Sometimes I'll have to sit down for a bit and maybe eat some lollies or drink some Powerade," Reid told afl.com.au.
"It's quick. I only have to prick my finger and then it takes five seconds to read so the maximum time I need is 20 seconds."
It's a routine Reid - and the interchange staff - will have to get used to. It will happen every time he comes off the ground, which can be as much as three or four times a quarter.
Reid is currently returning from a groin injury through the VFL and is using the time to perfect both his pre-game routine and what happens during his breaks.
He's confident his diabetes won't affect the way he plays the game after learning how to control it since his November diagnosis.
His levels are relatively stable, he doesn't have as many "hypos" (hyperglycaemic attacks caused by a sudden drop in blood sugar) as he once did, and his weight is under control after he initially gained four kilos as part of his four daily insulin injections.
He also believes the diagnosis, and his subsequent work with the Juvenile Diabetes Research Foundation (JDRF), has matured him.
"It wakes you up. One day I didn't have it and then next day I've got this life changing thing," Reid said.
"In a way, it's helped my football because I have to be so prepared with everything.
"I used to be really shy and wouldn't start a conversation with anyone. Now I've got more people skills because I'm meeting more people."
While Reid is learning to live with his disease, he admits there are aspects of it he'll never get used to including the self-administered injections and curbing his sweet tooth.
"I hate needles. The first time I did it, it took me ages," he said.
"Now, if I hit the same spot too many times in my stomach, it really hurts and I still pull it out before I even put the insulin in."
Reid says he now thinks of himself as a role model for people that have the disease and hopes he can inspire others to follow his example.
"Kids with diabetes think they can't do anything, so I thought if I'm going to get better I have to do this and do it right," he said.
"Before I got diagnosed, I didn't even know what it really was. It's changed my thoughts on it and now I want to help a lot of people understand what it is.
"I get letters saying, 'I didn't think I'd be able to play football with diabetes and now you've got it, I know I can do stuff'."
Reid is an ambassador for JDRF and recently participated in Spin to Cure diabetes, a cycling fundraising event run by the foundation.
