CDH screening is not done commonly and is often found incidentally. Affected patients can range from being symptomatic to asymptomatic. Second trimester screening can determine cases through the use of ultrasonography and MRI, methods that have been able to detect  60% of right-sided defects and more than 80% of those with left-sided CDH. Patients with polyhydramnios and an extended familial history of CDH dating back three generations should undergo further testing for diagnosis confirmation. Methods to evaluate for CDH include chorionic villus sampling, amniocentesis as well as chromosomal microarray analysis with the help of SNPs.
