A complete blood count (CBC), also known as a full blood count (FBC), is a set of medical laboratory tests that provide information about the cells in a person's blood.The CBC indicates the counts of white blood cells, red blood cells and platelets, the concentration of hemoglobin, and the hematocrit (the volume percentage of red blood cells).

Mean platelet volume (MPV) is a machine-calculated measurement of the average size of platelets found in blood and is typically included in blood tests as part of the CBC. Since the average platelet size is larger when the body is producing increased numbers of platelets, the MPV test results can be used to make inferences about platelet ...
This is the most common human hemoglobin tetramer, accounting for over 97% of the total red blood cell hemoglobin in normal adults. [55] hemoglobin A2, (HbA2) is a second form of adult hemoglobin and is composed of two alpha and two delta chains. This hemoglobin typically makes up 1-3% of hemoglobin in adults. [55]
Anemia can be confirmed by a blood test if the hemoglobin value is less than 13.5 gm/dl in men or less than 12.0 gm/dl in women. [39] Several countries have blood banks to fill the demand for transfusable blood. A person receiving a blood transfusion must have a blood type compatible with that of the donor. Sickle-cell anemia
During pregnancy the plasma volume increases by 40-50% and the red blood cell volume increases only by 20–30%. [22] These changes occur mostly in the second trimester and prior to 32 weeks gestation. [24] Due to dilution, the net result is a decrease in hematocrit or hemoglobin, which are measures of red blood cell concentration.
Anemia – A target hemoglobin level of 100–120 g/L is recommended; [67] [68] raising hemoglobin levels to the normal range has not been found to be of benefit. [69] Guidelines recommend treatment with parenteral iron prior to treatment with erythropoietin. Replacement of erythropoietin is often necessary in people with advanced disease. [70]
The "68–95–99.7 rule" is often used to quickly get a rough probability estimate of something, given its standard deviation, if the population is assumed to be normal. It is also used as a simple test for outliers if the population is assumed normal, and as a normality test if the population is potentially not normal.
