How do you calculate RBC indices?
RBC is per million cells. MCV = Hct × 10/RBC (84-96 fL) •Mean corpuscular Hb (MCH) = Hb × 10/RBC (26-36 pg) •Mean corpuscular Hb concentration (MCHC) = Hb × 10/Hct (32-36%) A rapid method of determining whether cellular indices are normocytic and normochromic is to multiply the RBC and Hb by 3.
How PCV is calculated?
The volume of packed red blood cells divided by the total volume of the blood sample gives the PCV. Since a tube is used, this can be calculated by measuring the lengths of the layers.
How is MCV calculated?
Mean corpuscular volume (MCV) is the average volume of red cells. It can be directly measured by automated hematology analyzer, or it can be calculated from hematocrit (Hct) and the red blood cell count (RBC) as follows: MCV in fl = (Hct [in L/L]/RBC [in x1012/L]) x 1000.
How do you calculate MCV MCHC?
MCHC/CHCM
- MCHC (g/dL) = (Hgb ÷ PCV) x 100.
- MCHC (g/dL) = (Hgb ÷ [MCV x RBC count]) x 100.
How are red blood cell ( RBC ) indices calculated?
Red Blood Cell (RBC) Indices Calculator. This red blood cell (RBC) indices calculator determines the MCV, MCHC and MCH which are the mean corpuscular volume, hemoglobin and Hb concentration of erythrocytes. Below the form you can find more information on the red blood cell indices, how each of them is calculated and what their normal ranges are.
What are the RBC indices for MCHC and MCV?
Taking the case of a patient with the following RBC parameters: ■ RBC = 4.6 x10 12 /L. ■ MCHC in g/dL = 13.5/43 x 100 = 31.39 g/dL (rounded to 31.4g/dL). 1) The McGill Physiology Virtual Lab (2016) Blood cell indices > MCV and MCHC. 2) Sharma R. (1990) Chapter 152, Red Cell Indices.
How to calculate the RBC count in g / dL?
The red blood cell (RBC) indices calculator uses the hemoglobin content in g/dL, the hematocrit value in % and the RBC count in 10 12 /L to determine the MCV, MCH and MCHC.
What is the normal RBC count in blood?
■ Hematocrit: The ratio of RBC to total blood volume, with normal values between 37 and 52% and determined via centrifugation of blood. ■ Red blood cell count: The number of RBC in the sample, with normal range between 4.2 and 6.3 x10 12/L.
