Understanding Your Results

The Parietal Cell Antibody IFA test is a qualitative test. It is important to interpret antibody results along with symptoms, vitamin B12 levels, and other investigations ordered by your doctor.
📊

Negative

No parietal cell antibodies detected. Autoimmune gastritis is less likely, but clinical correlation is still required.

📊

Positive

Parietal cell antibodies detected. This suggests possible autoimmune gastritis and further evaluation is recommended.

⚠️ When to Consult a Doctor:

If you have a positive test result or persistent gastric symptoms, consult your doctor for a complete assessment. Do not stop or start any medication without medical advice.

Limitations

  • ⚠A positive test does not diagnose autoimmune gastritis alone; clinical, endoscopic and other laboratory findings are needed.
  • ⚠A negative test does not completely exclude autoimmune gastritis, especially in early stages.
  • ⚠Test results should not be used for self-diagnosis or self-treatment.

Risks & Considerations

  • ●Mild pain or bruising at the blood collection site
  • ●Dizziness or light headedness during the blood draw
  • ●Very low risk of infection when aseptic technique is used

Interfering Factors

  • ●Immunosuppressive medications may lower antibody levels and cause false-negative results.
  • ●Recent blood transfusion or immunotherapy can interfere with antibody testing.
  • ●Hemolysed or lipemic samples may affect assay performance.

Frequently Asked Questions

What is the Parietal Cell Antibody IFA test?
It is a blood test that detects antibodies against the parietal cells of the stomach. These antibodies are often present in autoimmune gastritis, a condition where the immune system attacks the stomach lining.
What is the cost of the test at DNA Labs India?
The test costs Rs 1731.6. Online bookings include free home sample collection in selected cities across India.
How is the test done?
A healthcare professional draws blood from a vein in your arm. The serum sample is then sent to the laboratory and analyzed using indirect immunofluorescence assay.
Do I need to fast before the test?
Overnight fasting is preferred, though it is not strictly mandatory. Your doctor or lab staff will guide you.
What does a positive result indicate?
A positive result means that parietal cell antibodies were detected in your blood. This may indicate autoimmune gastritis, and your doctor may advise further evaluation.
What does a negative result mean?
A negative result means no parietal cell antibodies were detected. However, it does not completely exclude autoimmune gastritis, so clinical correlation is important.
What are the symptoms of autoimmune gastritis?
Symptoms may include abdominal pain, nausea, bloating, loss of appetite, weight loss, fatigue, and sometimes symptoms related to vitamin B12 deficiency such as tingling or anaemia.
Why are parietal cells important?
Parietal cells produce stomach acid needed for digestion and intrinsic factor, a protein essential for vitamin B12 absorption.
What sample is needed for this test?
A serum sample of 2 mL (minimum 1 mL) is required, usually collected in an SST (serum separator tube).
What is the turnaround time for the report?
If the sample reaches the laboratory by 9 am, the report is generally delivered the same day.
Is home sample collection available?
Yes, free home sample collection is offered for online bookings for eligible locations across India.
Are there any other tests that may be done with this test?
Your doctor may order tests such as anti-intrinsic factor antibody, vitamin B12, serum gastrin, complete blood count, or ferritin to support the diagnosis.
