Hindi ko sure ng exact price kasi nag-vary sa different labs and clinics here sa Pilipinas, but from what I've heard from my mum friends, usually anywhere from 500 to 2,000+ pesos depending kung saan ka magpa-test and ano specific na serum test ang kailangan mo. Best thing is to call ahead sa clinic or lab mo to ask directly, some ng hospitals may mas mura, some mas mahal, and may promo pa minsan especially if bulk tests yung kailangan mo!
