Cystatin C, in Guwahati

Fasting and dietary instructions:

No fasting is required for this test. However, as a general precaution, avoid alcohol and a heavy, fatty meal the evening before any blood test. These can temporarily alter several commonly tested markers even in tests that do not require strict fasting.

Medication guidance:

If you take NSAIDs (such as ibuprofen or diclofenac), certain antibiotics, or contrast agents, inform your doctor before the test. These medications can transiently elevate creatinine and urea levels, and your doctor may advise a brief medication pause if it is clinically safe to do so.

What to bring:

Carry your doctor's test order, a photo ID, and your corporate OPD insurance card to the appointment. If you have had this test done before, bring your previous reports , comparing values over time is clinically more meaningful than interpreting a single reading in isolation.

Timing:

Morning appointments are recommended for most blood tests. Biological markers tend to be most stable before meals and physical activity, giving the most consistent, comparable results. Booking an early slot also means you can eat and resume normal activity sooner after the test.

When does a doctor order Cystatin C?

Doctors order Cystatin C 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 Cystatin C done?

Cystatin C is often included in kidney function panels or used to calculate an alternative eGFR. Doctors may order it if you have reduced urine output, swelling, high blood pressure, fatigue, or abnormal creatinine. Adults above 30 benefit from including Cystatin C in a periodic preventive health panel. People with chronic conditions such as diabetes, hypertension, or autoimmune disease, those on long-term prescription medication, and individuals with a relevant family history should have this test at the frequency their doctor recommends.
