You can get a referral to KKH from polyclinic ! Then KKH will arrange the appointment accordingly for you (it will be reflected on healthhub app) when they receive the referral from polyclinic. If you are already in the KKH system, they will do all the necessary bookings of appointments for you. There isn’t really a speed for the slot, but in the first tri, usually appointments are a month apart.
if u go poly to ask referral letter u can ask dem for the earliest date and also if u book under poly u can get subsidies if u book straight from KKH it will be private
