WebCRC = (Reticulocyte level in % x Hematocrit level in %) / Normal hematocrit in %. For example, if the patient's reticulocyte count is 2.5%, their hematocrit level is 40%, and the reference normal hematocrit level is 45%, the calculation would be: CRC = (2.5 x 40) / 45 = 2.22%. Interpret the corrected reticulocyte count in conjunction with other ...
