Figures in many Northern Renaissance paintings look a little strange by the Italian Renaissance standards. People often have slightly elongated heads and strange-looking faces, but overall their proportions are realistic. Northern Renaissance painting lacks the classical references found in Italian art.
A. MCH stands for mean corpuscular hemoglobin. It estimates the average amount of hemoglobin in each red blood cell, measured in picograms (a trillionth of a gram). Automated cell counters calculate the MCH, which is reported as part of a complete blood count (CBC) test. MCH may be low in iron-deficiency anemia, and may be high in anemia due to vitamin B12 or folate deficiency. Other forms of anemia can also cause MCH to be abnormal.
Not to be confused with mean corpuscular hemoglobin concentration, although they are predictably correlated in healthy states. The mean corpuscular hemoglobin (MCH) , or mean cell hemoglobin (MCH), is the average mass of hemoglobin per red blood cell in a sample of blood.It is reported as part of a standard complete blood count.CH value is diminished in hypochromic anemias. It is calculated by dividing the total mass of hemoglobin by the number of red blood cells in a volume of blood. MCH=(Hgb*10)/RBC. A normal value in humans is 27 to 31 picograms/cell.
