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.
Iron:
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.
