MCV is the measurement of the average red blood cell volume and is used to classify red blood cells based on size 3,4. 100 fL. Macrocytic. Note: If the MCV is measured directly, it may be increased if there are many reticulocytes present.3. 2.
The carriers of either β° or severe β++ mutations have relatively high red blood cell count (RBC), while (MCV = hematocrit/RBC number) and mean corpuscular hemoglobin (MCH = Hb/RBC number) are markedly reduced (MCV: 60–70 fl; MCH: 19–23 pg). The Hb levels vary widely and they can be from normal to up to 2 g/dL.
To calculate the MCHC, expressed as grams of hemoglobin per 100 ml packed cells, the following formula is used: The normal ranges for MCV and MCHC are as follows: Sample problem: calculate the MCV and the MCHC for a subject with a red blood cell count of 4x10 6 per cubic mm, a hematocrit of 40% and a hemoglobin concentration of 12 g/dl.
Calculate the MCV, MCH, MCHC. Fill in the units in the chart above; Does this patient have anemia? Describe the morphological features of the anemia. Further lab tests were ordered, and the results were: Serum iron: normal. TIBC: normal. Ferritin: normal. HbA2: 7%. What type of anemia does the patient have? Why were the iron studies performed?
It is reported as part of a standard complete blood count. MCHC may be calculated from the MCV (Mean cell volume) and the MCH (Mean Corpuscular Hemoglobin) or from the hemoglobin (HGB) and hematocrit (Hct) values by using the following formula: MCHС (g/dL) = hemoglobin (in g/dL) × 100 / Hematocrit (in %) (1) or
