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.

"I'm a little biased as I work here! However, I love that The Bloody Good Test tracks my health over time. After turning 40, I wanted to make sure I wasn't going to drop dead from something basic I should have known about earlier. Measuring all my core biomarkers each year gives me peace of mind my health is on the right track"

Overview

Your kidneys work like your body's master filtration system, constantly cleaning waste and excess fluid from your blood around the clock. The eGFR (estimated Glomerular Filtration Rate) test acts as a sophisticated performance check for these vital organs, measuring how efficiently your kidneys can filter blood by calculating how much they process per minute. Unlike basic kidney tests that only look at waste levels in your blood, eGFR creates a personalized assessment by factoring in your age, gender, and other individual characteristics to give you a complete picture of how well your filtration system is actually working.

This test is particularly valuable because it can detect kidney problems early, often before you feel any symptoms, and helps stage kidney disease from mild to severe. Whether you have diabetes, high blood pressure, take certain medications, or have a family history of kidney issues, eGFR testing provides crucial insights that help your healthcare provider protect your kidney health and adjust treatments as needed. Think of it as your kidney report card – giving you and your doctor the information needed to keep these essential organs functioning at their best for years to come.

Symptoms

Essential for anyone with diabetes, high blood pressure, or family history of kidney disease. Critical for medication dosing and monitoring chronic kidney disease progression. Valuable for comprehensive health assessment and cardiovascular risk evaluation, as kidney function closely relates to heart health.

Questions

  • Creatinine is the raw measurement, while eGFR is a calculated result that adjusts for age, gender, race, and body size, providing a more accurate assessment of actual kidney function.
  • Kidney function naturally decreases by about 1% per year after age 30 due to normal aging processes, which is why age-adjusted reference ranges are used for interpretation.
  • While you can't reverse kidney damage, eGFR decline can often be slowed or stabilized through blood pressure control, diabetes management, lifestyle changes, and proper medication management.
  • For people with kidney disease or risk factors, eGFR should be checked every 3-6 months. For healthy individuals, annual screening is often sufficient, but may be more frequent for those over 50.
  • Stage 1-2: Normal/mildly reduced function; Stage 3: Moderately reduced (may need specialist care); Stage 4: Severely reduced (prepare for kidney replacement therapy); Stage 5: Kidney failure (need dialysis or transplant).
  • Yes, certain medications can temporarily or permanently affect kidney function. Always inform your doctor about all medications, and some may need dose adjustments based on eGFR levels.

How to prepare

No fasting required. Can be taken at any time of day. Ensure accurate reporting of age, gender, and race as these factors are used in the calculation. Inform your healthcare provider about medications that might affect kidney function. Stay normally hydrated before testing.

After the test

If eGFR shows reduced kidney function, discuss with your healthcare provider about further evaluation and kidney protection strategies. May require referral to nephrologist, additional testing (urine protein, kidney imaging), blood pressure optimization, diabetes management, medication adjustments, and lifestyle modifications. Regular monitoring helps track progression and guide treatment.

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.

If your test needs fasting, we’ll include that in your instructions after you order. Fasting usually means no food for 8–12 hours, but water is fine.

Just your pathology referral form (we email it to you)
