Kidney Function Panel (Creatinine/eGFR, Urea, Electrolytes)
Last reviewed 25 August 2026 · Evidence-graded review — see Methodology
Creatinine — used to estimate glomerular filtration rate — together with urea, sodium and potassium. Reduced kidney function is both a marker and a driver of cardiovascular risk, and chronic kidney disease stays asymptomatic until it is well advanced. That combination of silent, consequential and cheap to detect is what a screening test is supposed to look like.
eGFR staging under KDIGO guidelines robustly predicts progression to renal failure, cardiovascular events and mortality across large international cohorts. It is one of the best-validated tests in general medicine.

Not covered in the current review
Singapore’s national screening committee has not reviewed this test in the current volume of its report, which covers nine conditions. That is not a verdict either way.

What you would actually pay
- Healthier SG
- Not subsidised
- MediSave
- Not among the screenings named for outpatient claims

What it costs when it is wrong
- Basis
- No published harm criterion found
- Severity
- Not documented
Not covered in the current volume of the committee’s report, so no harm criterion was found either way.
An empty finding, not a clean bill of health: this means nothing documented was found for this test. It is not a claim that the test is safe.
Screening harm is not only a laboratory question: the committee’s own criteria advise against a test when “the screening test, or follow-up tests arising from a positive screen, are associated with significant medical risks”. Sources on overdiagnosis → · How this is graded.

Kidney Function Panel (Creatinine/eGFR, Urea, Electrolytes) carries a strong evidence grade for screening adults without symptoms. It is most appropriate for everyone, as part of a basic panel. It typically costs S$15–25 in Singapore. The usual schedule: every 1–3 years in average-risk adults; annually with hypertension, diabetes, or nephrotoxic medications.
