Implication

Investigation shows age-related decline in red blood cell deformability in humans and murine models, indicating potential for assessing biological age.

Key Points

This research aims to evaluate red blood cell deformability as a marker of biological age and to improve detection sensitivity.
Developed an ultrasensitive microfluidic device based on the spleen's filtration mechanism.
Standardized hematocrit levels and adjusted osmolarity in human samples for consistent measurements.
Analyzed murine models of varying ages (1 to 18 months) for differences in RBC deformability.
Statistically significant differences in RBC deformability were observed among different age groups in murine models.
A clear distinction in deformability was found between young and older humans, with a diagnostic cutoff speed of 0.9 mm/s.
Demonstrated a diagnostic performance with an area under the curve of 0.84, sensitivity of 78.3%, and specificity of 73.9%.
