There are a number of novel prenatal cytoogenetic analysis tests for obstetricians and gynecologists on detecting aneuploidies. In the recent years, screening of pregnant patients with non-invasive prenatal testing (NIPT) is one. As the spread of genomic medicine and preventive obstetrics continue, it is prudent for obstetricians and gynecologists to accept and optimize new screening modalities, whenever available.

Chromosomal abnormalities are common. Worldwide, one out of 150 live births may involve chromosomal abnormalities. The American College of Obstetrics and Gynecologists (ACOG) and American College of Medical Genetics recommend invasive and non ? invasive prenatal testing (NIPT)3. The invasive testing, however, carries risk for procedure ? related miscarriage. 4This favors NIPT which avoids the risk. The current state of NIPT in the Philippines, is it was only in January 2018, were a NIPT workshop was conducted by the Society of Maternal Fetal Medicine.6

First, due to the minimal studies on personalized and precision medicine on prenatal testing, hence the strong move to conduct this study. In an extensive literature search review in Herdin, a local database and archives of Philippine Obstetrics and Gynecology, none specified researches on non ? invasive prenatal testing.

Second, in our country alone, there is no provision for national prenatal tests. In our institution, it was already introduced but with no uptake yet. Because of this gap, scantiness and non - uptake on NIPT locally, hence the conduct of this study. The study aimed to investigate on the obstetricians and gynecologists (OB-GYNs) knowledge, attitude towards and practices (KAP) about NIPT. Majority of the OBGYNs were knowledgeable, had positive attitude and were practicing NIPT. Strikingly, a fourth of the respondents were not comfortable in explaining NIPT. The researcher recommends that there is a need to conduct this study on a larger scale cross - sectional survey and multiple studies due to the paucity of data.
