WebReticulocytes appear in the blood 2-4 days after sudden blood loss. Therefore repeat sampling may be necessary. To determine if anemia is regenerative or non-regenerative. Other reticulocyte calculations are the absolute reticulocyte count and the reticulocyte production index (RPI).

Frest Anticoagulated blood collected in a EDTA tube 2. Reticulocytes are newly produced red blood cells. They are slightly larger than totally mature red blood cells, and have some residual ribosomal RNA. The presence of RNA allows a visible blue stain to bind or, in the case of fluorescent dye, result in a different brightness. This allows them to be detected and counted as a distinct population.

"WebJun 4, 2024 · RPI is defined as follows: RPI = (RET% × HCT) : (0.45 × days in blood). 0.45 represents the ideal haematocrit in the formula. At this 'ideal' HCT of 0.45, RPI is identical to the reticulocyte percentage, which is 'ideally' about 1% in normal healthy individuals. In an anaemic patient with adequate bone marrow response, the RPI should be > 2.0. " - Rpi calculation hematology

WebCell Indices - hematology. Ability of red cells to withstand hemolysis when placed in hypotonic solutions. WebThe RPI can be calculated based on peripheral blood maturation time (RPI-C or RPI-S). In this study, the AMRC showed strong correlations with both the RPI-C and RPI-S (r2 = 0.87 and 0.76 respectively). Modern hematology analyzers are able to directly report both the reticulocyte count (%) and ARC.
