Which of the following compounds are used as agents to determine Glome

1.	Which of the following compounds are used as agents to determine Glomerular Filtration Rate?(a) Calcium ion(b) Albumin(c) Creatinine(d) Calcium carbonateThis question was posed to me by my school principal while I was bunking the class.My doubt stems from Drugs Excretion topic in portion Prodrugs & Excretion of Drugs of Drug Biotechnology
Answer» Right choice is (c) Creatinine To elaborate: GFR is determined by AGENT which is excreted exclusively by glomerular filtration and is neither secreted nor reabsorbed in the tubules. The excretion RATE of such compounds is 120-130 ml/min. The compounds USED are creatinine, INSULIN, mannitol, sodium thiosulfate.
