Chorionic Villi Culture – Karyotyping

Overview

Chorionic Villi Culture – Karyotyping is a prenatal diagnostic test performed on chorionic villi (placental tissue) collected during pregnancy. The test helps evaluate the baby’s chromosomes to detect genetic abnormalities, chromosomal disorders, and structural rearrangements.

This advanced cytogenetic analysis provides a detailed view of the fetal chromosome structure and number, enabling early detection of inherited or developmental conditions.

Why This Test is Done

This test may be recommended for:

• Advanced maternal age
• Abnormal ultrasound findings
• Positive prenatal screening results
• Family history of genetic disorders
• Previous pregnancy with chromosomal abnormalities
• Recurrent miscarriages
• Suspected fetal genetic conditions

Conditions Detected

Chorionic Villi Culture – Karyotyping can help identify:

• Down Syndrome (Trisomy 21)
• Edwards Syndrome (Trisomy 18)
• Patau Syndrome (Trisomy 13)
• Turner Syndrome
• Klinefelter Syndrome
• Structural chromosomal abnormalities
• Translocations and inversions
• Aneuploidies and mosaicism

Sample Required

• Chorionic villi tissue obtained through CVS (Chorionic Villus Sampling)

Test Method

• Cell Culture
• Chromosome Analysis / Karyotyping
• G-Banding Cytogenetic Technique

Benefits of the Test

• Early prenatal chromosomal diagnosis
• Accurate detection of major chromosomal abnormalities
• Supports informed pregnancy management
• Helps genetic counseling and risk assessment
• Useful for high-risk pregnancies

Turnaround Time

• Typically 10–21 days depending on culture growth

Preparation

• Usually no special preparation required
• Procedure performed only under specialist supervision

Important Notes

• This is an invasive prenatal diagnostic procedure.
• Genetic counseling is recommended before and after testing.
• Results should always be interpreted by a qualified fetal medicine specialist or geneticist.

FAQ

Is Chorionic Villi Culture – Karyotyping safe?

The CVS procedure carries a small procedural risk and is performed by experienced specialists under ultrasound guidance.

When is this test usually performed?

Typically between 10–13 weeks of pregnancy.

What is the difference between CVS and amniocentesis?

CVS uses placental tissue and is done earlier in pregnancy, while amniocentesis uses amniotic fluid and is usually performed later.

Can this test confirm genetic disorders?

Yes, it can accurately identify many chromosomal abnormalities and structural chromosome defects.
