Hi mama! Placenta Doppler is usually available sa major hospitals and diagnostic centers like Ultrasound Boutique, Philippine Heart Center, or private OB clinics, best to call your OB directly kasi sila na mag-refer ng best place para sa iyo. Ang cost ay around 2,500-4,500 pesos depending sa clinic, pero some cases ay covered ng insurance or may subsidy sa government hospitals, kaya worth asking talaga! A few of my mum friends did it during their pregnancy at ang doctors nila talaga ang nag-advise kung kailangan, so I'd suggest talking to your OB muna about whether it's needed para sa case mo, they'll also know kung saan best makakuha at may options for affordability.
