Comparison of gamma camera-based methods to measure glomerular filtration rate in potential kidney donors.

Introduction: The aim of this study was to compare two gamma camera-based methods (Gates' method and Inoue's method) for measuring glomerular filtration rate (GFR) with Russell's two plasma sample clearance method (2-PSC), which was taken as the gold standard.

Materials And Methods: In 94 healthy potential kidney donors (25 women and 69 men), GFR was measured by means of the 2-PSC method and was compared with Gates' and Inoue's methods of assessing GFR after technetium-99m-labeled diethylene triamine penta-acetic acid (⁹⁹ mTc-DTPA) injection.

Results: Inoue's method showed no statistically significant difference (P=0.

Reference range variation in haematological indices amongst five different age groups of less than one year in Islamabad, Pakistan.

Objective: The objective of the current study was to establish the reference ranges of haematological indices amongst five healthy infantile (<1 year) age groups.

Methodology: It was a descriptive cross sectional study carried out at the Department of Haematology, Armed Forces Institute of Pathology (AFIP), Rawalpindi. Non probability convenience sampling was adopted for the proceedings for the study.
