Affordable clinics

Hello po. Any suggestion po for affordable and good clinic to do laboratory tests and ultrasounds.. Hindi kasi covered ng health card. Sampaloc, QC near Manila, or Makati areas. Maybe I can consider Mandaluyong din. Nung TVS ko po kasi, nag St. Luke's QC ako, wala kasing idea. Ayun, sobrang mahal 3k+. Thank you po.
