Here is my experience with Tsan Yuk: I went for the 12 week checkup and scan, and had blood taken for unspecified test and weighed and measured. They told me I had to come back 4 days later for the scan (I think they were too busy). I returned for the scan, and that midwife was very friendly and patient, spent a long time on getting baby to turn so we could have a proper look at him/her. I had another blood sample taken, and they told me that it was not NIPT but a more standard screening test which can tell you about Down's syndrome with about 80% accuracy as opposed to almost 100% with NIPT. They told me they don't offer NIPT but I had the option to pay myself (8k or so) to have it done upstairs in the HKU clinic.
