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

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.
