In vitro hematocrit measurement using spectrally encoded flow cytometry

Area of Science:

• Biomedical Engineering
• Clinical Diagnostics
• Optical Imaging

Background:

• Accurate measurement of physiological parameters from small blood samples is crucial for point-of-care clinical diagnosis.
• Blood hematocrit, the volume fraction of red blood cells, is a fundamental parameter in all blood tests.

Purpose of the Study:

• To develop and evaluate an in vitro method for precise hematocrit measurement.
• To assess the feasibility of using spectrally encoded flow cytometry for real-time blood analysis.

Main Methods:

• Utilized spectrally encoded flow cytometry to acquire data from blood samples.
• Analyzed reflectance confocal images of blood within a flow chamber.
• Developed a novel method for in vitro hematocrit evaluation.

Main Results:

• Achieved a low measurement error of 1.7% for hematocrit.
• Demonstrated the capability of the technique for precise blood parameter analysis.
• Validated the method using in vitro blood samples.

Conclusions:

• The developed method provides accurate in vitro hematocrit evaluation.
• This technique can be integrated into point-of-care diagnostic systems.
• Enables real-time measurement of key blood parameters, improving clinical diagnosis.
