Do I need to fast before a PET CT?
You may be asked to fast for 4-6 hours before the scan. You can usually drink water. Your doctor will give you specific instructions.
How much does a PET CT cost in India?
Prices for PET CT vary widely by city, lab, and accreditation. As a rule of thumb, NABL-accredited labs in metros are more expensive than standalone neighbourhood labs. Use Locatemycentre to compare verified centres near you.
Can I get a PET CT with home sample collection?
Yes. Almost every NABL-accredited diagnostic centre in metros like Bangalore, Delhi, Mumbai, Chennai and Hyderabad offers home sample collection for PET CT. Book the night before, especially for any fasting tests, and confirm the visit fee (typically ₹100-₹250).
How long do PET CT results take?
Most routine PET CT reports are ready within 6-24 hours of sample collection. Specialised assays and tests sent to a parent lab may take 2-7 days. Confirm the exact turnaround with the centre before booking - it matters if you have a follow-up consult scheduled.
How will I receive the report?
Reports are emailed as a PDF and are usually downloadable from the centre's patient portal using your registration ID. Hard-copy collection at the counter is usually free; courier delivery is optional. Save the digital copy - your physician will want to see it alongside any prior reports.
Do I need a doctor's prescription for a PET CT?
For most routine versions of PET CT you can walk in without a prescription. Some advanced or restricted tests require a referral by law, and a physician's involvement is always recommended so the result is interpreted against your symptoms and history.
When should I repeat a PET CT?
Repeat timing depends on the clinical reason for the test. For monitoring a known condition, your physician will set the interval (often every 3-6 months). For a screening test that came back normal, repeat as part of your annual health check unless your doctor advises otherwise.
