FDG PET/CT

FDG PET/CT is used to measures tumour markers to screen for or monitor specific types of cancer. It is clinically indicated for patients undergoing cancer screening, active oncology monitoring, or post-treatment follow-up. GetVisit provides access to this test with transparent pricing, NABL-accredited labs, and cashless OPD from major insurers.
What is a FDG PET/CT Test in Mysuru ?
What is FDG PET/CT?
FDG PET/CT measures a specific biomarker in the blood that can be elevated in the presence of malignancy. Tumour markers are produced either by cancer cells directly or by the body in response to cancer. Results must always be interpreted alongside imaging and clinical findings.
What does FDG PET/CT measure?
FDG PET/CT measures how much a radioactive glucose tracer (FDG) is taken up by body tissues. Tissues that use more glucose, such as many cancers, infections, or inflamed areas, show higher uptake. This gives a map of metabolic activity inside the body. The specific marker measured depends on the test your doctor has ordered. A blood sample is typically collected from a vein in the arm using a standard venipuncture technique. The sample is then sent to a NABL-accredited laboratory where it is analysed using validated, quality-controlled equipment. Results are reported with reference ranges and returned digitally.
What do the results of FDG PET/CT mean?
Results are reported as numerical values alongside the laboratory reference range for your age and gender. A value within the reference range is considered normal for most clinical purposes. Values outside the range are flagged as high or low and discussed by your doctor in the context of your symptoms and medical history. Not every out-of-range value indicates disease , your doctor will determine what it means for you specifically.
FDG PET/CT Test Preparation in Mysuru
Fasting and dietary instructions:
Do not eat or drink anything except plain water for 8 to 12 hours before the test. Drinking water freely is encouraged , it keeps you hydrated and makes venipuncture easier. Avoid tea, coffee, juice, milk, and chewing gum during the fasting window even if they are taken without sugar.
Medication guidance:
Continue taking all regular prescribed medication unless your doctor has specifically asked you to stop before this test. Inform the lab staff about all medications, supplements, and herbal remedies you are currently taking. Some substances affect specific test values, and this information helps your doctor interpret results accurately.
What to bring:
Bring your doctor's test requisition or prescription, a valid government-issued photo ID, and your health insurance card if you plan to use cashless OPD benefits. Wear clothing that allows easy access to the inside of your elbow , a short-sleeved top or a sleeve that can be rolled up comfortably.
Timing:
For most blood tests, a morning appointment after overnight fasting gives the most standardised results. If your test does not require fasting, a morning slot is still preferable as it minimises the influence of the day's food intake and physical activity on marker levels.

Why Take a FDG PET/CT Test in Mysuru ?
When does a doctor order FDG PET/CT?
Doctors order FDG PET/CT both reactively , when you have symptoms that need investigation , and proactively, as part of preventive health monitoring. The test result provides measurable data that guides decisions about medication, lifestyle changes, specialist referral, or further diagnostic investigation.
Who should get FDG PET/CT done?
FDG PET/CT is an imaging study commonly used in cancer care and whole-body evaluations. It is ordered when doctors suspect a tumor, see an unclear mass on other scans, or need to stage known cancer. Anyone with persistent, unexplained symptoms , fatigue, weight changes, recurrent infections, or pain , that have not yet been investigated should include FDG PET/CT as part of their diagnostic workup. Adults above 35 who have not had a comprehensive health panel in the past year should also consider it as part of a routine preventive assessment.
What happens after the results are ready?
Once your results are available, book a follow-up consultation with your doctor or a GetVisit-verified specialist to review the findings. Your doctor will explain what each value means, compare it against the reference range, and advise on the next steps , whether that is lifestyle guidance, a repeat test, medication adjustment, or a referral. All GetVisit reports are stored digitally and can be shared with any doctor or specialist instantly from your phone.
