Sample Requirements:
SST tube
Purpose:
Monitors kidney function using BUN and creatinine which reflect glomerular filtration, as well as electrolytes that regulate fluid balance. Important for hypertension, diabetes, and chronic kidney disease monitoring. eGFR helps stage kidney dysfunction.
Reference Range:
Creatinine: 0.7–1.3 mg/dL; BUN: 7–20 mg/dL; eGFR: >60 mL/min/1.73m²; Electrolytes: Sodium 135–145 mmol/L, Potassium 3.5–5.1 mmol/L, Chloride 98–107 mmol/L.
