    Now I am a stickler for accuracy and seeing some people asking what the new numbers for HbA1c meant I sorted out an easy conversion formula to work both ways.

    So, if you want to quickly convert your present HbA1c numbers to the new IFCC HbA1c numbers here is the formula:
    Present (HbA1c) - 2.15 x 10.929 = IFCC HbA1c
    Example: 7.5% - 2.15 x 10.929 = 58.47 rounded down to 58.

    To convert the opposite way.
    IFCC HbA1c ÷ 10.929 + 2.15 = Present HbA1c %
    Example: 48 ÷ 10.929 + 2.15 = 6.54 rounded down to 6.5%
