What is blood test?

What does a blood test show?

Some blood tests can help your doctor determine how different organs in your body are working. Examples of organs whose malfunctions can be visible in a blood test include your thyroid, liver, or kidneys.

Your doctor can also use blood tests to search for markers of diseases and health conditions such as:

  • diabetes
  • HIV
  • anemia
  • cancer
  • coronary heart disease

Even if a person does not have heart disease, a blood test can show whether they may be at risk of developing the condition.

Other blood tests can indicate whether the medications you’re taking are working properly, or assess how well your blood is clotting.
