Understanding Your Results

Results indicate the presence or absence of 1p and 19q codeletion, which is key for diagnosing oligodendroglioma and predicting treatment response.
Positive for codeletion: Associated with oligodendroglioma and favorable response to chemotherapy.
Negative for codeletion: May indicate other tumor types or require further testing.
Consult with an oncologist to understand implications for treatment.
⚠️ When to Consult a Doctor:

If you experience symptoms like persistent headaches, seizures, or neurological changes, or if you have a brain tumor diagnosis, consult an oncologist or neurologist for test evaluation.

Limitations

  • ⚠Test is specific to oligodendroglioma and may not apply to other brain tumors
  • ⚠Requires adequate tumor tissue for accurate analysis

Risks & Considerations

  • ●No direct risks to the patient; test is performed on tissue sample.

Interfering Factors

  • ●Poor tissue quality
  • ●Insufficient tumor content in sample

Frequently Asked Questions

What is the FISH 1p & 19q Codeletion Test?
It is a genetic test using fluorescent probes to detect deletions on chromosomes 1 and 19 in brain tumor tissues, helping diagnose oligodendroglioma.
Why is this test performed?
To identify specific genetic abnormalities for accurate diagnosis, prognosis, and personalized treatment planning in brain tumors.
What are the symptoms of oligodendroglioma?
Common symptoms include headaches, seizures, nausea, vomiting, changes in vision or hearing, and personality changes.
How is the test performed?
The test is performed on a formalin-fixed paraffin-embedded tissue block from biopsy or surgery, analyzed in a lab using FISH technology.
What is the cost of the FISH 1p & 19q Codeletion Test?
The cost is INR 12000, which includes home sample collection in many cities across India.
How long does it take to get results?
Results are typically available within one week after sample submission.
Is home sample collection available?
Yes, free home collection is offered for online bookings across numerous cities in India.
What sample is required for the test?
A formalin fixed paraffin embedded tissue block with at least 10% tumor tissue is required.
What does a positive result mean?
A positive result indicates the presence of 1p and 19q codeletion, associated with oligodendroglioma and better response to chemotherapy.
What does a negative result mean?
A negative result suggests no codeletion, which may indicate other tumor types or need for further diagnostic tests.
Is the test covered by insurance?
Coverage depends on your insurance plan; it is not typically covered under government schemes like PMJAY or CGHS without prior approval.
How to prepare for the test?
No special preparation is needed, but ensure the tissue sample is collected properly and the requisition form is submitted.
