I have notice some inaccurate information on the above posts.

Correct info are as follows.
1) booking can be made at PPUM klinik antenatal counter as soon as you know you are pregnant. Just bring what ever photo/report from private clinic or pink book if you went to Klinik Kesihatan earlier. No referral letter is required.
2) first check up appointment is usually 2 months later from your booking date.
3) need to pay RM500 deposit + RM 31 registration during first check up. Inborn Error of Metabolism Test (RM80 - Optional) payable during first appointment if you wish to do it when your baby is born later.
4) earliest first check up appointment will be in July 2019 now.

not necessary to do check up at PPUM, but we prefer to do it there because hospital is still better than KK with greater facilities. Especially if you have any complications during pregnancy. Nothing can't be done at PPUM so far except 4d, 5d, 6d scan. You can do normal ultrasound, NT scan, anomaly scan, OGTT and etc. there.
