Understanding Your Results

Results indicate the chromosomal makeup of the baby. Abnormalities may require further testing and genetic counseling.
📊

Normal Karyotype

No chromosomal abnormalities detected, indicating typical chromosomal makeup.

📊

Trisomy 21

Indicates Down syndrome, characterized by an extra chromosome 21.

📊

Monosomy X

Indicates Turner syndrome, where one X chromosome is missing or altered.

📊

Other numerical abnormalities

May indicate various genetic disorders such as Edwards syndrome or Patau syndrome.

📊

Structural abnormalities

Includes deletions, duplications, or translocations, which may lead to genetic conditions.

⚠️ When to Consult a Doctor:

Consult a doctor immediately if results show abnormalities or if the child exhibits symptoms of genetic disorders, such as delayed development or unusual physical features.

Limitations

  • ⚠Cannot detect single gene disorders
  • ⚠May not identify all microdeletions
  • ⚠Requires cell culture, which may fail in some cases

Risks & Considerations

  • ●Minimal risk similar to blood collection
  • ●Possible minor infection at collection site
  • ●Rare chance of culture failure requiring repeat sampling

Interfering Factors

  • ●Clot formation in sample
  • ●Improper storage
  • ●Sample not received within 24 hours

When should this test be performed?
Test is recommended between 18-20 weeks of gestation for prenatal planning, with sample collected at birth for analysis.
What is the cost of the test?
The cost is INR 4000 at DNA Labs India, inclusive of home collection and report delivery.

Yes, free home sample collection is available for online bookings across numerous cities in India.
How long does it take to get results?
Results are typically available within 10 working days from sample receipt at the laboratory.
What do the results mean?
Results indicate the chromosomal makeup; normal karyotype means no abnormalities, while abnormal results may indicate genetic disorders requiring further consultation.
Are there any risks associated with the test?
Risks are minimal, similar to blood collection, including minor infection at the site or rare culture failure.
Can this test detect all genetic disorders?
No, it primarily detects chromosomal abnormalities; single gene disorders or small mutations may require additional tests like FISH or microarray.
What should I do if abnormalities are found?
Consult a genetic counselor or specialist immediately for interpretation, further testing, and management options.
How accurate is this test?
The test is highly accurate for detecting chromosomal abnormalities when performed under controlled laboratory conditions, with results reviewed by experts.
