Description
Trisomy 21,18,13
Over 10 weeks
Sample Type:Serum
Tests Included:
The Harmony Prenatal Test is a non-invasive prenatal screening test assessing fetal DNA in maternal blood for chromosomal abnormalities (such as Down syndrome), fetal sex, and specific genetic conditions.
Sample Required:
Blood sample from the pregnant woman.
Test Time:
Results are usually available within a couple of weeks.
Test Range Values:
Interpretation is based on the presence or absence of specific chromosomal abnormalities or genetic conditions.
What is the test?
The Harmony Prenatal Test screens for chromosomal abnormalities and genetic conditions in the fetus using cell-free fetal DNA from the mother’s blood.
Test Procedure:
Blood is drawn from the pregnant woman, and the fetal DNA is analyzed for chromosomal abnormalities and genetic conditions.
When to take the test:
It’s often recommended in the first trimester (after 10 weeks of pregnancy) for women at increased risk or as part of routine prenatal screening.
Who should take the test:
Pregnant women seeking early and non-invasive screening for chromosomal abnormalities or specific genetic conditions in the fetus might opt for this test.
Precautions for exceptional cases (if any):
No specific precautions are necessary for the test procedure.
Frequently Asked Questions (FAQs) for Harmony Prenatal Test:
Q1: How accurate is the Harmony test in detecting chromosomal abnormalities?
A: It’s highly accurate for detecting common chromosomal abnormalities, with a low false-positive rate.
Q2: Does a positive result mean the baby definitely has a genetic condition?
A: No, a positive result indicates an increased risk, and further diagnostic testing (like amniocentesis or CVS) might be recommended for confirmation.
Q3: Can the Harmony test determine the baby’s sex?
A: Yes, it can determine the fetal sex, which can be useful for sex-linked genetic conditions or for gender determination if desired.
Q4: At what stage of pregnancy can the Harmony test be performed?
A: It’s typically performed after 10 weeks of pregnancy when there’s enough fetal DNA in the maternal blood.
Q5: Is the Harmony test suitable for all pregnant women?
A: It’s often offered to women at increased risk for chromosomal abnormalities or genetic conditions, but individual circumstances and preferences should be discussed with a healthcare provider.
