Hay, alam mo, this is a sensitive thing kaya better to consult with a lawyer or ask your OB/GYN for proper referrals, they usually know the accredited labs in Manila na legit and private pa. A few of us mums have gone through family concerns like this, and the hospitals like Medical City or St. Luke's usually have genetics labs na pwedeng gawin, pero important talaga na may professional guidance kaya you know your rights and ang process ay smooth. Good luck, sis, sending you strength.
