Aims:
The aim of the study was to evaluate the accuracy of two devices that measure hemoglobin (Hb) from blood samples taken from small capillary tubes (HemoCue® Hb 301 System) and another from whole blood taken from veins or arteries (Horiba H550) with a laboratory reference analyzer (Beckman Coulter DxH 520).
Subjects And Methods:
A cross-sectional study was conducted, in which capillary and venous blood samples were taken from 529 individuals across outpatient and inpatient wards of both genders, with an age range from 7 to 83 years. The accuracy and agreement were statistically evaluated using Lin's concordance correlation coefficient.
Results:
We observed a higher diagnostic accuracy in the venous blood-based point-of-care device than in the capillary blood-based device in classifying the anemia.
Conclusions:
The Horiba H550 shows remarkable accuracy in classifying the anemia closer to the laboratory reference. Further, this study underlines the significance of blood samples collected from venous in measuring Hb levels.

01:30Equipments Used To Measure Blood Pressure
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...
