[PubMed: 3968826]Payne BA, Pierre RV, Morris MA. ^ MedlinePlus Medical Encyclopedia: RBC indices . MCHC as measured by the electronic machines is mostly normal in microcytic anemias, however, and the value of MCH closely parallels the value of MCV. Conditions such as hyperlipidemias, hyperbilirubinemia, a very high white blood cell count, and high serum protein can interfere with this measurement and result in falsely elevated hemoglobin values.Presence of immunoglobulins or fibrinogen precipitated by low temperatures in the blood sample leads to interference with cell counts, resulting in spuriously increased white blood cell count and sometimes small elevations in hemoglobin, hematocrit, red blood cell count, and a slight decrease in MCV. The size distribution of a population of cells is graphically represented by the red cell histograms (Price–Jones curves) (see Figure 152.1). Clinical SignificanceAnemias may be classified based on their etiology (e.g., hemolytic, hemorrhagic, etc.), erythropoietic response (e.g., hypoproliferative, ineffective), or cell morphology (e.g., macrocytic, microcytic-hypochromic).Red cell indices are valuable in the morphologic classification of anemias.


There is anisocytosis, and RDW is often increased. It is, therefore, important to examine the peripheral smear in the evaluation of anemias. 1979;300:1277. Two types of automated machines are generally used. In contrast, when there is defective and delayed synthesis of hemoglobin, the continued cell division leads to microcytosis. Am J Clin Pathol. In red cell agglutination, doublet erythrocytes are counted as one, and larger clumps are not counted as red blood cells at all. Termed red cell indices, these values are useful in elucidating the etiology of anemias. Thalassemia minor: routine erythrocyte measurements and differentiation from iron deficiency.


In contrast to MCH, MCHC correlates the hemoglobin content with the volume of the cell. [PubMed: 6881096]Bessman JD, Gilmer PR, Gardner FH. Measure Units Conventional units Conversion Hct 40% Hb 100 grams/liter 10 grams/deciliter (deci- is 101) RBC 5E 12 cells/liter 5E 6 cells/L (micro is 106) MCV = Hct / RBC 8E-14 liters/cell 80 femtoliters/cell (femto- is 1015) MCH = Hb / RBC 2E-11 grams/cell 20 picograms/cell (pico- is 1012) MCHC = MCH / MCV 250 grams/liter 25 grams/deciliter (deci is 101) . M C H C = H b H c t {displaystyle MCHC={frac {Hb}{Hct}}} x 100 Normal range: 32-36 g/dL . Something went wrong. Improved classification of anemias by MCV and RDW.


The MCV and MCH are increased, while the MCHC remains normal. 1985;2:37988.Rose MS. 1983;14:50914.Gottfried EL. Please try refreshing this page, or going back. Spurious results from automated hematology cell counters. Mean corpuscular hemoglobin concentration (MCHC) is the average concentration of hemoglobin per unit volume of red blood cells and is calculated by dividing the hemoglobin by the hematocrit. The normal value for RDW is 13 1.5%. N Engl J Med. We apologize for the inconvenience.

The normal values for MCHC are 34 2 g/dl.RDW represents the coefficient of variation of the red blood cell volume distribution (size) and is expressed as a percentage. Worked example[edit].
