    Changes in pH affect red blood cell (RBC) deformability. Lowering or increasing pH decreased RBC deformability in NaCl solutions, while alkaline pH increased it in Teitel solutions.

    Area of Science:

    • Hematology
    • Biophysics
    • Physiology

    Context:

    • Red blood cell (RBC) deformability is crucial for microcirculation.
    • Altering physiological pH can impact cellular function.
    • Filtration techniques are used to assess RBC mechanical properties.

    Purpose:

    • To investigate the impact of pH variations on red blood cell deformability.
    • To compare the effects of pH on RBCs in different solution types (NaCl vs. Teitel).

    Summary:

    • Red blood cell deformability decreased in 0.9% NaCl solutions when pH was lowered or raised from neutral.
    • In Teitel solutions, RBC deformability exhibited an increase specifically at alkaline pH levels.
    • The study utilized a filtration technique to quantify changes in RBC deformability under varying pH conditions.
