Blood and Body Fluid Precautions

Topic Overview

What are blood and body fluid precautions?

Blood and body fluid precautions are recommendations designed to prevent the transmission of HIV, hepatitis B virus (HBV), hepatitis C virus (HCV), and other diseases while giving first aid or other health care that includes contact with body fluids or blood. These precautions treat all blood and body fluids as potentially infectious for diseases that are transmitted in the blood. The organisms spreading these diseases are called blood-borne pathogens.

Blood and body fluid precautions apply to blood and other body fluids that contain visible traces of blood, semen, and vaginal fluids. They also apply to tissues and other body fluids, such as from around the brain or spinal cord (cerebrospinal fluid), around a joint space (synovial fluid), in the lungs (pleural fluid), in the lining of the belly and pelvis (peritoneal fluid), around the heart (pericardial fluid), and amniotic fluid that surrounds a fetus.

The wide range of symptoms associated with mononucleosis can make diagnosis difficult. Your doctor will begin by giving you a complete physical exam. A throat culture may be taken to rule out strep throat, which has similar symptoms. The doctor may take a blood sample to look for the presence of abnormal white blood cells. A heterophile antibody test, commonly called a “Monospot,” may also  be done. This test examines the blood for special antibodies that your body produces in response to a viral...

Why are blood and body fluid precautions important?

Although skin provides some protection from exposure to potentially infectious substances, it is strongly recommended that health professionals use blood and body fluid precautions for further protection when they are providing health care. These precautions also help protect you from exposure to a potential infection from your health professional in the unlikely event that you come in contact with the health professional's blood.

The American Red Cross recommends that everyone use blood and body fluid precautions when giving first aid.

Are blood and body fluid precautions always needed?

The best practice is to always use blood and body fluid precautions, even when you can't see any blood and there's no chance that blood is present. But the precautions aren't absolutely needed if you don't see any blood when you come in contact with other body fluids, such as:

  • Breast milk.
  • Stool.
  • Mucus from the nose or lungs.
  • Sweat.
  • Tears.
  • Urine.
  • Vomit.

How can you reduce your risk of exposure to blood and body fluids?

Blood and body fluid precautions involve the use of protective barriers such as gloves, gowns, masks, and eye protection. These reduce the risk of exposing the skin or mucous membranes to potentially infectious fluids. Health care workers should always use protective barriers to protect themselves from exposure to another person's blood or body fluids.

  • Gloves protect you whenever you touch blood; body fluids; mucous membranes; or broken, burned, or scraped skin. The use of gloves also decreases the risk of disease transmission if you are pricked with a needle.
    • Always wear gloves for handling items or surfaces soiled with blood or body fluids.
    • Wear gloves if you have scraped, cut, or chapped skin on your hands.
    • Change your gloves after each use.
    • Wash your hands immediately after removing your gloves.
    • Wash your hands and other skin surfaces immediately after they come in contact with blood or body fluids.
  • Masks and protective eyewear, such as goggles or a face shield, help protect your eyes, mouth, and nose from droplets of blood and other body fluids. Always wear a mask and protective eyewear if you are doing a procedure that may expose you to splashes or sprays of blood or body fluids.
  • Gowns or aprons protect you from splashes of blood or body fluids. Always wear a gown or apron if you are doing a procedure that may expose you to splashes or sprays of blood or body fluids.
