It is also called an erythrocyte count” (Cafasso J. ,2012).The red blood cells have a vital function in carrying oxygen throughout the body in order for the body to function well.

White blood cells which is also called leukocyte play a very important role in the immune system. White blood cells attack the viruses and bacteria by fighting the infection which tries to harm our body. As stated by Higuera V. (2012), a white blood cells count is a test that measures the number of the white blood cells in the body. The white blood cells count can fluctuate according to our health status. An average normal range for white blood cells is between 4500 and 10000 mcl (Higuera V.,2012). So, if the result of the test was higher or lower than the range, the result is said to be abnormal. A low or high white blood cells count may cause many medical conditions. A high white blood cells count can be described in the term of leukocytosis. There are many conditions that can cause the elevated number of the white blood cells. Some of the examples are tumors in the bone marrow, inflammatory conditions such as arthritis and bowel disease, tissue damage, pregnancy and also allergies. Leukemia is the disease which is related to the high white blood cells count. On the opposite side, when the count is low, Leukopenia may occur. Some condition that can make the count become low are HIV, bone marrow disorders, lymphoma, liver and spleen diseases and lastly, radiation

While O’Connor connects Enoch’s lack of faith to his animalistic tendencies, one can also ascertain that Enoch completely immerses himself in his wise blood because his life lacks a love for God and other people, promoting the theme that without divine or human love one can only act like an animal. O’Connor’s introduction to Enoch establishes his lonely, unloved existence.

The osmotic fragility test can be performed on freshly taken red cells. The susceptibility to osmotic lysis is primarily determined by the surface area to volume ratio of erythrocytes .Increased osmotic fragility typically occurs in hereditary spherocytosis. Because of their reduced surface membrane area in respect to the cell volume, spherocytes take up less water in a hypotonic solution before rupturing than do normal blood cells. They cannot expand as much as normal discoid erythrocytes and are osmotically more fragile ( Roper and Layton, 2012
