Pakiet Nerkowy — Renal Panel

Kidney function panel with creatinine (including eGFR calculation), urea, uric acid, electrolytes, and urinalysis. At 170 PLN (~€39), a comprehensive renal assessment covering both blood and urine markers.

This panel provides a thorough assessment of kidney function through both serum and urine markers. Creatinine with eGFR (estimated glomerular filtration rate) is the primary screening tool for chronic kidney disease — eGFR below 60 mL/min/1.73m² sustained for 3+ months defines CKD stage 3. Urea (blood urea nitrogen) rises with reduced kidney filtration but is also influenced by dietary protein intake and hydration status, making it a useful but less specific marker than creatinine. Uric acid elevation indicates either overproduction or underexcretion — relevant for gout risk and as an independent cardiovascular risk factor. Electrolyte balance (sodium, potassium) is directly regulated by kidney function. Potassium dysregulation is particularly dangerous as it affects cardiac rhythm. Calcium and phosphorus metabolism is also kidney-dependent, with chronic kidney disease causing secondary hyperparathyroidism and bone mineral loss. The urinalysis component detects proteinuria (protein in urine) — an early marker of kidney damage that often precedes changes in creatinine. Microalbuminuria in diabetic patients is a critical screening target as it identifies nephropathy at a reversible stage. Individual components: creatinine + eGFR 23 PLN, urea 22 PLN, uric acid 22 PLN, electrolytes 34–49 PLN, urinalysis 25 PLN.
