A blood test is a common medical procedure where a small sample of blood is taken from a person's arm or hand to be tested in a laboratory. Blood tests are used for multiple purposes, such as:
-
Assessing General Health: Blood tests can provide information about a person's overall health status.
-
Detecting Infections: They can help confirm the presence of bacterial or viral infections in the body.
-
Organ Function: Blood tests can evaluate how well certain organs like the liver and kidneys are functioning.
