Hi mama! MCA ultrasound (middle cerebral artery) is usually done during pregnancy to check baby's blood flow, especially kung may concerns about anemia or other issues, a few of us had it done kasi recommended ng OB, and it typically costs anywhere from 2,500 to 5,000 pesos depending sa clinic, but honestly better to call your hospital directly kasi ang presyo talaga varies. Which clinic are you planning to go to? The private hospitals here in the metro tend to be a bit pricier than government hospitals, pero lahat ng results are pretty reliable naman.
