- A blood culture is a test that looks for germs (such as bacteria or fungi) in the blood.
- If germs are found, the test also can help doctors know which medicines will work best to treat the infection.
- A blood culture is done when a child has signs of an infection that might be caused by bacteria or fungi.
- It also might be done if a child has an infection in one part of the body that may have spread into the blood.
- Most blood tests take a small amount of blood from a vein. To do that, a health professional will:
- clean the skin
- put an elastic band (tourniquet) above the area to get the veins to swell with blood
- insert a needle into a vein (usually in the arm inside of the elbow or on the back of the hand)
- pull the blood sample into a vial or syringe
- take off the elastic band and remove the needle from the vein
