During the test, blood is drawn from your body. After which, laboratory workers analyze it. Sometimes, they use the whole blood to count your blood cells. At other times, they separate your blood cells from its fluid (also known as plasma or serum).

The plasma is utilized to measure various substances within the blood. The results of this measurement can lead to the early detection of health problems. It is important to note that doctors won’t rely on blood tests alone to diagnose conditions as other factors are used to confirm a diagnosis. These factors might include results from other procedures and tests, medical history, signs and symptoms, and vital signs.

For most blood substances, a normal range is based on levels found within 95% of healthy people in a particular group.

Results of your blood tests might show that you fall out of the normal range. This might be due to various reasons. Abnormal findings may be a sign of disease or disorder. It might also be caused by other factors such as level of physical activity, diet, medicine intake, and alcohol consumption, among others.

The doctor will discuss any abnormal or unusual results with you. These types of results may or may not be a sign of health challenges. Blood tests are a great way to detect health conditions and diseases early. The detection of these problems can lead to lifestyle changes and treatments at an earlier time, which is better compared to identifying health problems when it’s already too late.
