  17. Dear Sagar

    Thank you for your interesting posts. Don’t you think the term “normal value” is better to change with “Reference Interval” as explained in CLSI and ISO terminology?

  18. Great!!! It’s vert helpful. Thank you

  19. Sagar,
    This is very impressive and shows passion for the profession on your side. What a commendable effort to make such a compilation for sharing. However may I know if a global geographical distribution difference was calculated as it has proved in my over 35 years of service in the field that blood value (normal) range from caucasian communities are not the same with the Afro-comminities. All the same your effort,once again,is very commendable.
