Growing popularity: Prenatal genetic screening is increasingly common, yet it has limitations in diagnosing various genetic disorders.
Detection challenges: While chromosomal abnormalities and certain single-gene disorders are identified, mitochondrial and epigenetic disorders remain difficult to detect.
Medical professionals' role: Combining genetic blood analysis with ultrasound can assess potential birth defects, but many conditions can only be diagnosed after birth.
Screening phases: Prenatal genetic testing occurs in stages with specific timelines for blood tests and ultrasound scans focused primarily on detecting chromosomal risks.
Optional but recommended: Basic screening is advised for all pregnancies, particularly for those with risk factors like advanced maternal age or family history of genetic disorders.
