Hi! I haven't given birth under their social service myself, pero a few of my mum friends have and they said it really depends on your classification, mas mura kung lower class ka, pero kahit may discount, you still need to budget para sa meds, labs, at room charges kaya better to ask directly sa St. Lukes admissions office para exact ng total. They're usually helpful pag tinatanong mo ng detailed breakdown based sa your specific classification!
