১. The most accurate substance for measuring glomerular filtration rate is:
ক) Para-aminohippuric acid (PAH)
খ) Inulin
গ) Glucose
ঘ) Urea
ঙ) Albumin
উত্তর দেখুন
সঠিক উত্তর: খ) Inulin
ব্যাখ্যা: Inulin is freely filtered and neither reabsorbed nor secreted, so its clearance equals GFR. PAH clearance measures effective renal plasma flow. Creatinine is used clinically.
