    Attention COACH STUDY participants:

    The principal investigators of the study request that you use the official version of the modified score here.

    Absolute Reticulocyte Count & Reticulocyte Index

    Assesses appropriate response to anemia, frequently in sickle cell patients.
    When to Use
    Why Use

    Determining if an anemic patient is mounting an appropriate response to their anemia, or if they have an inadequate marrow response (either from the marrow itself or a nutrient deficiency, or the blood loss was too rapid for reticulocyte response).

    The laboratory “reticulocyte count” is actually a percentage. The absolute count corrects for the level of anemia, and the reticulocyte index determines if the reticulocyte count is appropriate for the level of anemia.
