Which blood test screening is more comprehensive for chromosome abnormalities?

Hi mommies, may I know what blood tests have you all chosen? My gynae would like to order Harmony and Oscar tests for me at week 12. But I have also heard from some girl friends that Oscar test is not necessary. Or Panorama is better. I’m a lil’ confused. Thanks for your sharing your experience.#advicepls #firstbaby #firsttimemom
