Mean Corpuscular Volume (MCV) This is the average volume of each red blood cell sampled. Differences in the average red blood cell volume explain why the PCV and RBC count do not always match. This can also be used to help identify causes of anaemia. Mean Corpuscular Haemoglobin (MCH) This is the average amount of haemoglobin in each red

The Hematological Complications of Alcoholism

the mean corpuscular volume (MCV) is significantly larger than normal. However, an increased MCV does not automatically lead to a diag-nosis of macrocytosis. For example, cells with an increased MCV can be found in patients with folic acid or vitamin B12 deficiency (as in the case of megaloblastic anemia) or with chronic liver disease

The Complete Blood Count and Associated Tests

The purpose of this course is to explain the normal blood values for the complete blood count and associated tests as well as implications of increased and decreased values. Upon completion of this course, the healthcare provider should be able to: Discuss the composition of blood. List 4 types of progenitor cells that produce blood cells.

The normal reference range for MCH is age dependent. The MCH value tends to be proportional to MCV. The size of a cell is largely determined by the haemoglobin content. Cells that have a normal MCH are referred to as normo-chromic whereas those with low values are termed hypo-chromic. Mean cell haemoglobin concentration

Three neglected numbers in the CBC: The RDW, MPV, and NRBC count

The mean corpuscular volume is the aver-age volume of red blood cells. Providers use it to classify anemia as either microcytic, normo-cytic, or macrocytic, each with its own differ-ential diagnosis. The differential white blood cell count provides absolute counts and relative percent-ages of each type of leukocyte. For example,

Diagnostic Evaluation of Anaemia - IntechOpen

The mean normal value for the MCHC is 34 grams of haemoglobin per dL of RBCs. Low values occur in the same conditions that generate low values for MCV and MCH, while increased values occur almost exclusively in the presence of congenital or acquired spherocytosis or in other congenital haemolytic anaemia in which red cells are abnormally

Overview of Mean Corpuscular Volume (MCV/HCT)

The mean corpuscular volume (MCV) is one of the standard red blood cell indices It is the volume of the average red blood cell, stated in femtoliters (fL) and it has been available as a reliable, directly measured value, for more than 40 years. Diagnosis of different types of anemia may be assisted by the mean corpuscular volume. 2.

Milder carriers may have a normal haemoglobin with minimal reduction in MCV and MCH while other carriers will have mild anaemia with more marked reduction in MCV and MCH.

cell. MCH levels generally increase or decrease in conjunction with changes in the MCV. A low MCH is associated with decreased hemoglobin production. Iron deficiency is the most common cause of a low MCH. Large cells (high MCV), as seen with vitamin B12 deficiency, generally have a higher than normal MCH.

In absolute anemia, RBCs, HGB, and/or

Mean Corpuscular Hemoglobin (MCH)

The MCH is expressed as picograms (pg) of hemoglobin (per average red cell). The MCH may be affected by cell size (MCV). MCHC corrects for cell volume and should be used for classification of anemia if different from the MCH value. A true increase in MCH is not possible as cells cannot contain an increased amount of hemoglobin.

If the MCV is normal and the RDW is high, there is a mixture of large and small RBCs If the RDW is normal and the MCV is high, the RBCs are likely all macrocytic If the MCV and RDW are both normal, the RBCs are likely all about the same normal size MCV = normal RDW = normal MCV = normal RDW = high

he MCV measures the average size of red blood cells. he average MCV ranges from 80 100 femtoliters (fL). A low MCV shows that cells are smaller than normal. his may be due to an iron deiciency or chronic disease.

Hematocrit (Hct), Hemoglobin (Hb or Hgb), Mean Corpuscular Volume (MCV), Mean Corpuscular Hemoglobin (MCH), and Mean Corpuscular Hemoglobin Concentration (MCHC) [5,26]. RBCs, Hgb and Hct can be measured directly in the lab, the rest are calculated based on previous values [27]. MCV, MCH and MCHC give evidence to support pathologies in RBCs [18,28].


The normal MCV for men and women is 92 ± 9 fL In electronic counters the MCV is determined by pulse height analysis. 15.3.2 Mean Corpuscular Haemoglobin or MCH MCH is the average mass of hemoglobin per red cell expressed in picograms.
