List of all pregnancy prenatal tests

Jes 0 Comments

This is just a list of all pregnancy tests that are done in Singapore. I consolidated it to prepare new mums on what to expect each time they head to the clinics. Do take a look at what to expect for first, second and third trimester too!

Week 6 - Trans-vaginal scan to check for the embryo/embryos. The gynaecologist will put a probe up your private part to do this so be sure to wear something easy to take off. You will know if you have twins or more at this point. It will not hurt but it is uncomfortable of course.

Week 8 - First ultrasound on belly. Start monitoring your weight.

Week 13 - Oscar test is around S$300+, this is a blood test and sent to a Singapore lab. If you are older than 35 years old or at high risk, you may be recommended to just go straight to do a Harmony test where it will cost S$1000+ as they will send it to a USA lab. The gender results can also be known with the Harmony test.

Week 16 - Gender test for those not doing Harmony test. You might be able to see it from the ultrasound. If it's a girl, there will be 3 lines. For boys, it should be quite obvious.

Week 21 - Detailed scan to check for abnormalities. I had to go TMC clinic (Thomson or Orchard) for the high end equipment as this is not the usual ultrasound used in normal clinics. It cost around S$188 including a CD of the scans. Gender test should be confirmed in this scan.

Week 21 or later - Glucose test for those who found their levels higher during Oscar test. Fasting is needed to be done the night before for 8 hours. No water can be drank so as not to dilute the blood results. You will have to do a blood test, which means they will draw blood from you before you drink a glucose liquid and after 1 hour of drinking it. This will determine if your body is able to metabolize glucose. If not, you will have to watch your sugar intake carefully.

Week 35 onwards - Swab test for Group B Streptococcus (GBS) bacteria infection. It means the gynaecologist will be using a cotton bud to sweep your genitals and send it to test for bacteria growth. If so, you might need to take antibiotics so that it will not affect the baby during vaginal birth. The gynae will also use a prop to widen your genitals to see if there is fungal infection. If so, you will need to insert a paste like medicine called Zalain down there like a tampon at night.

Week 36 onwards - Your gynae might insert his/her fingers down there to check if you are dilated. 1 finger inserted means 1cm.

There might be a urine test every time you visit the gynae to check if there is high level of proteins.

Not to worry, all these tests are pretty painless compared to the actual labour itself. All the best to a smooth delivery!
