Cystatin C Blood Test

$90.00 AUD

Want the most accurate assessment of kidney function, especially if you have diabetes or high blood pressure, or monitoring kidney health in high-risk situations?

The Cystatin C test measures a protein in your blood that reflects how well your kidneys are filtering waste. It may help detect early kidney problems, sometimes before changes show in standard creatinine tests, and may also be linked to heart health risk.

Simple health checks in my control

I didn't know that private blood tests were an option. Tried this platform as the packages suited what I wanted for a good price. Easy to follow instructions, and super quick results. Platform provides more information than my gp's ever have on the tests and what the results meant. Would like more clinics to be able to test at (specifically Capital Pathology) but there is a decent network. Will continue to use.

Overview

Think of Cystatin C as your kidneys' honest report card. While traditional kidney tests can be thrown off by things like your muscle mass, age, or what you ate for dinner, Cystatin C tells the straight truth about how well your kidneys are actually working. This small protein acts like a reliable messenger that's produced steadily by all your cells and filtered exclusively by your kidneys – kind of like having a consistent flow of tennis balls that only your kidneys can catch and process.

What makes this test special is that it can spot kidney problems much earlier than standard tests, giving you a valuable head start on protecting your kidney health. If your Cystatin C levels are elevated, it means your kidneys aren't filtering as efficiently as they should be, which could signal the early stages of kidney disease or other kidney-related issues. This test is particularly helpful if you have diabetes, high blood pressure, or other conditions that put your kidneys at risk, and it's especially accurate for older adults, children, or anyone whose muscle mass might make other kidney tests less reliable.

Symptoms

Essential for individuals with kidney disease risk factors, need precise kidney function evaluation, or anyone requiring accurate renal health assessment independent of muscle mass.

Questions

  • Cystatin C is less affected by muscle mass, age, gender, and diet, providing more accurate kidney function assessment, especially in elderly, children, and those with unusual muscle mass.
  • Elevated cystatin C indicates reduced kidney function (lower GFR), suggesting kidney disease that requires further evaluation and management to prevent progression.
  • Yes, cystatin C can detect declining kidney function earlier than creatinine, allowing for earlier intervention and better preservation of kidney health.
  • Cystatin C is primarily affected by kidney function, though thyroid disorders and certain medications may have minor effects, making it more reliable than creatinine.
  • Cystatin C-based GFR estimates help determine appropriate doses for medications eliminated by the kidneys, reducing risk of toxicity or treatment failure.
  • People with diabetes, hypertension, cardiovascular disease, family history of kidney disease, elderly individuals, or those where accurate kidney function assessment is crucial.

How to prepare

No special preparation required. Inform healthcare provider of all medications and medical conditions that might affect kidney function or cystatin C levels.

After the test

Address elevated cystatin C through comprehensive kidney evaluation, blood pressure and diabetes management, nephrology consultation, lifestyle modifications, and regular monitoring. Protect remaining kidney function.

Your test results will be available in your private dashboard. If there are any urgent issues, we'll let you know so you can follow up with your health professional.

Understanding results

Results show cystatin C levels and calculated GFR. Elevated levels indicate reduced kidney function requiring further evaluation, monitoring, and appropriate interventions to preserve kidney health.
