1. A method for preparing a cellular hemoglobin A1c (Hb A1c) control comprising:

  • (a) selecting a sample of red blood cells with at least one desired feature from a suitable subject;

    (b) washing the sample;

    (c) processing the washed sample to remove white blood cells;

    (d) preserving Hb A1c molecules in said sample, wherein said red blood cells are intact and said Hb A1c molecules are unmodified;

    (e) washing the sample of (d); and

    (f) adjusting the Hb A1c level to the predetermined level thereby producing a cellular Hb A1c control, wherein the level of Hb A1c of the control is substantially stabilized and detectable.
