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.
A simple calculation is used to determine the mean corpuscular hemoglobin level in blood. According to Med Friendly, the total amount of hemoglobin in the sample is multiplied by ten and then divided by the number of red blood cells present. CBC (complete blood count) blood test can be used to monitor MCH levels in blood. Lab Tests Online explains that the MCH aspect of a CBC test âis a measurement of the average amount of oxygen-carrying hemoglobin inside a red blood cell.
