Gestational Diabetes Test & Lucozade

Ladies,I’m scheduled for my glucose tolerance test in 2 weeks & I’m just curious if anyone knows if drinking Lucozade can impact it?Ive packed in coffee & all other drinks in my pregnancy but I do confess,lucozade is definitely my go to drink…I drink maybe a small bottle or 2 a day which my midwife says is OK but now I’m just curious if there is any impact on my GD test with this drink?
