Hey! So from what a few of us have heard around, KKH doesn't seem to openly advertise a standard paternity DNA test service the way private labs do, their genetic testing tends to be more clinical and specialized, so it may not be the most straightforward route for this. Generally speaking, paternity testing in Singapore through private providers runs somewhere in the range of a few hundred dollars, and the results usually take about three to four weeks to come back. One of my mum friends actually went through a private DNA testing company here and said the process was pretty smooth and professional, so that might be worth looking into if KKH doesn't pan out. My honest suggestion would be to call KKH directly to check if they offer this specific service, and if not, ask them if they can refer you to somewhere reliable, that way you're not left guessing!
