Determination of Hematocrit Interference in Blood Samples Derived from Patients with Different Blood Glucose Concentrations

Determination of hematocrit interference in blood samples derived from patients with different blood glucose concentrations.

BACKGROUND We performed a blood glucose meter hematocrit (HCT) interference test with lower sample manipulation requirements by using blood samples from patients with different blood glucose (BG) levels. METHODS Blood from five patients with different BG levels (2.8, 5.6, 8.3, 13.9, 19.4 mmol/liter) was manipulated to contain five different HCT concentrations (35/40/45/50/55%). Each sample w...

Hematocrit interference of blood glucose meters for patient self-measurement.

BACKGROUND Abnormal hematocrit levels may interfere with glucose readings of patient self-assessment blood glucose (BG) meters. The aim of this laboratory investigation was to assess the potential influence of hematocrit variations on a variety of BG meters applying different measurement technologies. METHODS Venous heparinized blood was manipulated to contain three different BG concentration...

Evaluation of hematocrit bias on blood glucose measurement with six different portable glucose meters.

INTRODUCTION Measurement and monitoring of blood glucose levels in hospitalized patients with portable glucose meters (PGMs) is performed widely and is an essential part of diabetes monitoring, despite the increasing evidence of several interferences which can negatively bias the accuracy of measurements. The purpose of this study was to evaluate the effect of the hematocrit on the analytical p...

RETICULOCYTE INTERFERENCE WITH LYMPHOCYTE SEPARATION IN BLOOD OF PATIENTS WITH KALA-AZAR

Determination of Alpha Particles Levels in Blood Samples of Cancer Patients at Karbala Governorate, Iraq

Introduction: Alpha particle emitters are very damaging and harmful when entering into the human body ,if   ingested or inhaled , swallowed or absorbed  into the lungs or bloodstream . Uranium (238U), Radium (226Ra) and Radon (222Rn) are typical alpha-particle emitters. Material and Methods: we measured the level of alpha particles emitted from 222Rn, 226Ra, and 238U in blood samples of 10 can...
