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

Think of creatinine as your kidney’s report card—it shows how well these hardworking organs are clearing waste from your blood. Your muscles release a small, steady trickle of creatinine every time they recycle energy. Although this production stays fairly constant day-to-day for each person, it does differ from one individual to another based on muscle mass, age, and sex. In healthy kidneys, creatinine is swiftly filtered out of the bloodstream and sent into the urine, so the amount left in your blood becomes a convenient snapshot of kidney function.

When blood creatinine starts to inch upward, it’s a quiet alarm that your kidneys may be falling behind. That’s important because kidney problems usually develop silently—people often feel fine while damage is happening in the background. Persistently elevated creatinine can point to chronic kidney disease, diabetes- or blood-pressure–related kidney damage, or side effects from certain medications. Because the test is quick, inexpensive, and largely unaffected by short-term changes in diet or exercise, it’s a staple of routine blood work that helps catch kidney trouble early, when treatment is most effective.

Symptoms

Essential for people with diabetes, high blood pressure, or family history of kidney disease. Important for monitoring medications that can affect kidney function. Valuable for anyone with cardiovascular disease, older adults, and those with risk factors for kidney problems.

Questions

  • Elevated creatinine typically indicates that your kidneys aren't filtering waste as effectively as they should. This could suggest kidney disease, dehydration, certain medications, or other conditions affecting kidney function.
  • Yes, certain medications including some antibiotics, blood pressure medications, pain relievers, and diabetes drugs can affect kidney function and creatinine levels. Always inform your doctor about all medications you're taking.
  • eGFR provides a more accurate assessment of kidney function by adjusting creatinine levels for age, gender, race, and body size, giving a better picture of how well your kidneys are working.
  • For people with kidney disease or risk factors, creatinine may be checked every 3-6 months or more frequently. For healthy individuals, annual checking as part of routine screening is often sufficient.
  • Extremely high protein intake or creatine supplements can temporarily raise creatinine, but dietary protein has minimal effect on the test. Normal dietary variations don't significantly impact results.
  • Both measure kidney function, but creatinine is more specific to kidney function while BUN can be affected by hydration, protein intake, and liver function. Creatinine is generally considered more reliable for kidney assessment.

How to prepare

No fasting required. Can be taken at any time of day. Inform your healthcare provider about medications, especially those that might affect kidney function. Avoid extremely high protein meals immediately before testing. Stay normally hydrated - don't over-hydrate or become dehydrated before testing.

After the test

Discuss elevated results with your healthcare provider immediately as this may indicate kidney problems requiring further evaluation. Additional testing may include eGFR calculation, urine tests, kidney ultrasound, or referral to a nephrologist. Treatment depends on the underlying cause and may include blood pressure management, diabetes control, medication adjustments, or specific kidney disease treatments.

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

Normal ranges vary by gender, age, and muscle mass. Men: 70-110 μmol/L (0.8-1.3 mg/dL); Women: 50-90 μmol/L (0.6-1.0 mg/dL). Elevated levels may indicate reduced kidney function, kidney disease, dehydration, or certain medications. Even small increases within the normal range can be significant for kidney function assessment when calculating eGFR.

Frequently Asked Questions

Most collection centres accept walk-ins. Some may require a booking - check details when you click on your chosen location.

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)
