| Summary: | ABSTRACT
Background
It becomes important to detect chromosomal abnormalities prenatally and early in the pregnancy. The
present thesis is aimed to assess the performance of prenatal screening tests for chromosomal
abnormalities detection i.e., dual marker test, first trimester ultrasound which measures the nuchal
translucency and presence or absence of nasal bone, and their correlation with diagnostic test which is the
karyotyping after amniocentesis.
Materials and Methods
It is a prospective & observational clinical study conducted in the Obstetrics and gynaecology department
of a tertiary care hospital. Two hundred pregnant females above 18 years of age attending ANC OPD
(Antenatal Check-up Out-patient department) were considered for this study.
Results
In this study we found the presence of chromosomal abnormalities in 10% of participants. Combined
sensitivity of NT and Dual marker test was found to be 83.75% in detecting chromosomal abnormalities.
Conclusions
It can be concluded at the end of the study that; prenatal diagnosis with ultrasonography for nuchal
translucency either alone or in combination with dual marker test offered good detection rate for these
chromosomal abnormalities.
