Hematology is nothing but the study of blood. Hematology includes the study of etiology, diagnosis, treatment, prognosis, and avoidance of blood diseases. Blood diseases affect the making of blood vessels and its components, such as blood cells, hemoglobin, blood vessels necessary protein, the mechanism of coagulation, etc.
Blood contains many different substances and contaminants which may be examined. Sometimes the cells are examined, other periods the fluid aspect of the blood (plasma) will be examined. Some of the blood tests are:
Full Blood Count:
This is a common test which investigates the three main types of tissues in the blood: red blood cells, white blood cells and platelets. Evaluation of red blood cells can tell the doctor if you are anaemic or not. Evaluation of white blood cells tissues will indicate the presence or lack of disease and how good your body is at fighting Hematology disease.
Blood Clotting: The capability of the blood vessels to clog normally can be calculated by: looking at the platelets, calculating the International Normalized Ratio, or a coagulation display. Patients on warfarin will need to have frequent INR assessments. Before having these tests everyone should eat and drink normally.
ESR (Erythrocyte Sedimentation Rate):
This test looks at the red blood cells and can indicate the use of an inflamation diseases or irregular proteins conditions such as a serious illness or ligament problem.
Tests such as serum iron and Ferritin evaluate the stages of iron in your blood vessels and total body. Low iron stages may cause anaemia while high stages of iron may indicate liver organ illness, swelling or certain cancers.
Vitamin B12 and Folate:

Vitamin B12 and folic acid are the natural vitamins most often calculated in blood tests. It is important for pregnant mothers of vitamin b complex folic acidity for the foetus to create normally. Low stages of these natural vitamins may indicate the use of some types of anaemia, especially in elders. Low stages may also be due to vegetarian, certain medicines or some illnesses of the digestive tract.
