Since a medical history and examination cannot identify all patients with blood-borne infectious agents, Standard Precautions should be consistently used for all patients. The blood and body fluids of every patient must be considered to be potentially infectious.
1. Body fluids to which Standard Precautions apply: blood, tissue, and other body fluids containing visible blood; semen and vaginal secretions; cerebrospinal fluid; synovial fluid; pleural, pericardial or peritoneal fluid and amniotic fluid.
2. Fluids to which Standard Precautions do not apply, unless they contain visible blood: feces, nasal secretions, sputum, sweat, tears, urine, saliva, vomitus, and breast milk.
