Results indicate the chromosomal makeup of the fetus. Normal results show 46 chromosomes with no structural abnormalities, while abnormal results may indicate genetic conditions requiring further consultation.
📊

No chromosomal abnormalities detected; fetus has typical chromosome number and structure.

📊

Presence of an extra chromosome, indicating conditions like Down syndrome.

📊

Deletions, duplications, or translocations in chromosomes, which may lead to genetic disorders.

Frequently Asked Questions

What is prenatal diagnostic screening by karyotyping?
It is a genetic test that examines fetal chromosomes to detect abnormalities like Down syndrome or other chromosomal disorders during pregnancy.
How is the test performed?
Fetal cells are collected via amniocentesis or chorionic villus sampling, then cultured in a lab to analyze chromosome structure and number.
What are the risks associated with the test?
Risks include a small chance of miscarriage, infection, cramping, or spotting, but these are rare when performed by experienced professionals.
How long does it take to get results?
Results are typically available within 15-20 days after sample collection.
Is the test covered by insurance?
Coverage varies by insurance provider; it is not typically covered under government schemes like PMJAY or CGHS, but check with your insurer.
What should I do before the test?
You need a doctor's prescription, except for pregnancy cases or travel abroad. No fasting is required, but discuss any concerns with your healthcare provider.
Can the test detect all genetic disorders?
No, karyotyping primarily detects chromosomal abnormalities; it may not identify single-gene disorders or other genetic conditions.

Who should consider this test?
Pregnant individuals with risk factors such as maternal age over 35, abnormal ultrasound findings, family history of genetic disorders, or previous chromosomal issues.
How accurate is karyotyping?
Karyotyping is highly accurate for detecting chromosomal abnormalities, but accuracy can depend on sample quality and laboratory expertise.
