What This Test Measures

This test detects specific DNA variations associated with *Morgagni syndrome*—a rare congenital heart defect where heart structures may be positioned unusually. The probe targets genetic sequences that could influence heart development.

Why It Might Be Ordered

Your healthcare provider may recommend this test if you or a family member have a history of congenital heart defects, or if symptoms like breathing issues, feeding difficulties, or heart murmurs are present.

How the Test Works

A small blood sample is taken to extract DNA. The DNA is analyzed using a specialized probe to identify any genetic changes linked to *Morgagni syndrome* or related cardiac anomalies.

What to Expect Before the Test

No special preparation is needed. A simple blood draw is performed, similar to other routine blood tests. Results may take several days to weeks, depending on lab processing.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Identifying genetic risks can guide prenatal care, fetal monitoring, or decisions about family planning. Early detection may help plan interventions like surgery or medical management to support heart function.

Frequently asked questions

How long does it take to get results?
Results typically take 7–14 business days, depending on lab workflow and genetic analysis complexity.
What does a positive result mean?
A positive result indicates a genetic variation linked to *Morgagni syndrome* or related heart defects. This does not always mean the condition will develop, but it may inform further testing or monitoring.
Can this test be used for prenatal screening?
Yes, this test can be performed during pregnancy if there’s a family history or suspicion of congenital heart defects. Consult your provider for prenatal options like amniocentesis or non-invasive prenatal testing.
