Prenatal screening and foetal diagnostics have undergone transformative evolution from biochemical serum screening to cell-free DNA analysis, advanced genomic sequencing, and high-resolution foetal imaging. The shift from invasive diagnostic modalities toward highly sensitive noninvasive prenatal screening (NIPS) has redefined risk assessment paradigms in obstetric care. This comprehensive analytical study evaluates technological, ethical, clinical, and psychosocial dimensions of contemporary prenatal diagnostics through a retrospective observational analysis of 520 pregnancies undergoing prenatal screening at a tertiary centre. Logistic regression modelling identified advanced maternal age (β=0.48, p<0.001), abnormal ultrasound markers (β=0.44, p<0.001), and positive NIPS results (β=0.56, p<0.001) as significant predictors of invasive diagnostic confirmation. Integration of NIPS reduced invasive procedures by 41% (p<0.01). Ethical concerns regarding informed consent and equitable access significantly influenced screening uptake (β=0.32, p<0.05). The final predictive model explained 82% of variance in diagnostic outcomes (R²=0.82). Findings support a paradigm shift toward precision prenatal medicine integrating genomic technologies, ethical governance, digital counselling platforms, and psychosocial screening frameworks.
