Overview
Laboratory findings consistent with the diagnosis of diaphragmatic hernia include decreased maternal alpha-fetoprotein and an ABG showing hypoxemia, metabolic acidosis, and hypercapnia.
Laboratory Findings
Antenatal tests
- Amniocentesis: karyotyping should be obtained to rule out associated chromosomal abnormalities.
- Maternal alpha-fetoprotein is decreased in CDH[1]
Postnatal tests
- Arterial blood gas: ABG may show hypoxemia, metabolic acidosis, and hypercapnia.
- The infant should be investigated for the presence of associated chromosomal abnormalities.[2]
