Hi mama! Honestly, I'd suggest calling around sa major hospitals like Quirino Memorial or Caloocan Medical Center kasi ang prices nila usually mas affordable compared sa private clinics, and you can ask them directly kung magkano exactly ang CAS nila ngayon. A few of us moms from my circle got ours done sa government hospitals and hospital chains tapos okay naman ang results, though you might need to wait a bit longer for slots, pero worth it para sa presyo talaga! Para sa best rates at availability, best to call ahead na lang kasi ang prices and promo schedules nila changes, and while you're at it, ask din kung may package deals sila with other prenatal tests. Take care!
