Preventive Kidney Assessment
The kidney is the silent organ.
It loses function on a curve, with no symptoms. By the time it hurts, the damage is past the window. Preventive kidney assessment looks at the kidney in the phase when there is still time to change the trajectory.
Why Look Earlier
Approximately 10% of the Brazilian adult population has some degree of chronic kidney disease. More than 90% don't know it. The kidney signals only after losing more than half of its function — and by then, much of what is lost does not come back.
That is why the preventive nephrology approach changes the agenda. We don't wait for creatinine to rise; we read cystatin C, albuminuria, urinary sediment, and 24-hour blood pressure pattern. We cross with the cardiometabolic profile — because the kidney and heart share a damage pathway. We adjust medications that overload the kidney before they cause a problem. We treat hypertension for nephroprotection, not just for the number.
Plenya's preventive kidney assessment is led by Dr. Getúlio Amaral Filho, a nephrologist (CRM-PR 21.876 · RQE 16.038), faculty member, and coordinator of the nephrology medical residency at Santa Casa de Londrina. The reading is specific: every test enters in context, every decision has a re-evaluation deadline.
Perguntas frequentes
Frequently asked questions about kidney assessment.
- The kidney is the silent organ. It loses function on a curve — without pain, without symptoms — and only signals when the damage is already irreversible. About 10% of the Brazilian adult population has chronic kidney disease, and most don't know it. Detecting it early, in the window when damage is still reversible or stabilizable, changes the trajectory of the next decade.
- Serum creatinine and estimated glomerular filtration rate (eGFR) are the basics — but insufficient on their own. The combination that changes clinical decisions: cystatin C (more sensitive in early stages), albuminuria (urinary albumin/creatinine ratio), urinalysis with microscopy, electrolytes, 24-hour blood pressure when indicated. ApoB and the metabolic profile enter because the kidney and the cardiovascular system are coupled.
- Anyone over 40. Anyone with hypertension, diabetes, obesity, or metabolic syndrome at any age. Anyone with a family history of kidney disease, early cardiovascular event, or a single kidney. Athletes who use intense protein supplementation or chronic anti-inflammatories. Patients on prolonged use of PPIs, lithium, or non-steroidal anti-inflammatories.
- In people with normal kidney function, the evidence is reassuring for creatine, omega-3, vitamin D, and magnesium. Concern concentrates on high doses of protein in those already with reduced function, anti-inflammatories used chronically without indication, unregulated imported supplements, and "kidney detox" formulas — which lack evidence and may mask real problems.
- The nephrologist reads the same tests with a magnifying glass: pattern of eGFR decline, fine interpretation of albuminuria by stage, medication adjustment by residual function, decisions about nephroprotectors in pre-clinical phase. For an asymptomatic patient, it is the difference between a stamp and a plan.
- Yes. Dr. Getúlio Amaral Filho is a nephrologist with RQE 16.038, faculty member at Santa Casa de Londrina and coordinator of the nephrology medical residency. Preventive kidney assessment is a structured part of the Continuum Plenya program, integrated with the cardiometabolic and functional reading.

Pre-diabetes is not a phase. It is a five-year window.
An HbA1c between 5.7% and 6.4% is usually treated as a vague warning — "let's repeat it in a year." The literature is more uncomfortable: every year without action increases the probability of progression and narrows the window in which reversal is still the most likely outcome.

Lp(a): the test your father's cardiologist didn't order
One in five people has elevated lipoprotein(a). It is genetically determined, doubles or triples the risk of heart attack and aortic stenosis — and almost never appears on a checkup. Measuring it once in a lifetime changes decades of clinical decisions.

Ferritin between 30 and 100: the normality that drains women
The lab clears it as normal starting at 15 ng/mL. But our team observes, in patients we follow longitudinally, that menstruating women with ferritin below 50 already live with real symptoms — fatigue, hair loss, dropping performance — without ever having become anemic.
