Reasons for Emergency Room Blood Tests at Dignity Health Southern California

Our emergency room doctors use blood tests in these critical cases:

  • Blood transfusion — if you need a blood transfusion, blood tests determine compatibility with banked blood.
  • Disease or organ dysfunction — clinical chemistry tests provide vital information about your heart, kidneys, and liver. These tests measure electrolytes, hormone levels, and enzymes. Our doctors can also administer a blood test for heart attack.
  • Drug toxicity or overdose — drug tests show the amount of a drug in the blood, such as alcohol, pain relievers, anti-seizure drugs, digoxin (atrial fibrillation drug), psychiatric medicines, and theophylline (for respiratory diseases).
  • Blood problems — hematology tests look at the amount of blood and plasma components. Examples include a complete blood count (CBC) and blood clotting tests.
  • Infection — microbiology tests detect bacteria, fungi, or parasites in the blood. These and other lab tests also help our doctors determine which drugs will work to fight the infection.
