Study Notes

  • Serology blood test detects and measures levels of antibodies due to exposure to bacteria or viruses.
  • Antibody levels help determine recent or past infection.
  • Serological testing is useful in diagnosing rickettsial and viral diseases, as well as conditions like syphilis.
  • Antibodies are produced by the immune system to fight off invaders.
  • Antigens provoke a response from the immune system and can enter the body through various means.
  • Antigens include bacteria, fungi, viruses, and parasites.
  • Whole blood specimens must be refrigerated and received within 24 hours of collection.
  • Serological testing is a practical mass-screening diagnostic tool.
  • Antibody titer helps determine acute or chronic infection.
  • Serological testing is particularly helpful in diagnosing infectious mononucleosis and rheumatoid arthritis.
