Why do you need a Blood Test


Our blood shows us a great deal about our health. Blood tests are used to diagnoseillness and are also useful as they can draw attention to health problems in their earlystages. For example, measuring Cholesterol levels helps to identify one of the risks ofheart disease, long before the condition becomes more serious.

  • Medical technologists use either whole blood or separate the blood cells from the fluid which is called plasma or serum, to analyse it.
  • A nurse needs to take a blood sample from you to conduct these tests.

Nurses use a new needle for each new patient, to eliminate any risk of being infected.The most common risk is slight bruising and discomfort where the needle has inserted into the vein, however, this should go away shortly after.

How is the test carried out?

A nurse draws a small amount of blood from a vein in your arm using a thin needle. Some tests can also can be done using a finger prick. Drawing blood usually takes just a few minutes and should not be painful.

What do the results show?
