Ay hindi ko sure ng exact prices dito sa San Fernando kasi laging nagbabago, pero try mo mag-inquire sa the bigger hospitals like Pamela Medical Center or Angeles University Foundation Medical Center, usually mas mababa ang rates nila compared sa private clinics! For placental mapping specifically, I'd suggest calling ahead para confirm na may available sila at detailed pricing, kasi sometimes mas mahal ang specialty ultrasound na yan compared sa regular OB sono.
