This is a bit personal so bear with me. I was just wondering if such a test is even possible before the baby is born or only after. Asking out of curiosity more than anything, dont judge pls.
Better to wait and do it after the baby is born unless its really urgent, the after birth test is simpler and totally safe. If it cant wait, only go through a proper lab via a doctor. Dont trust random online kits for something this important.
It is possible technically, but i would strongly suggest talking to a doctor rather than going by online labs. There can be legal and consent angles too. Your gynac can point you to a proper certified centre if you genuinely need it.
This is really something to discuss directly with a doctor, as some methods can carry risk to the pregnancy. Please dont go to any random place for it. A specialist can tell you the safe options.
From what i know yes, there is a non invasive prenatal paternity test done with the mothers blood sample, but its specialised and not available everywhere in India. Best to ask a good diagnostic lab or your gynac about whether and where its done safely.
