Immunity Detection & Titer Tests

Immunity detection and titer tests are diagnostic assessments used to evaluate an individual's immune response to specific pathogens or vaccines. These tests typically involve analyzing a blood sample to measure the levels of antibodies produced by the immune system in response to infection or vaccination. Antibodies, also known as immunoglobulins, are proteins that target and neutralize pathogens such as viruses or bacteria. Immunity detection tests assess whether an individual has been previously exposed to a particular pathogen or has developed immunity following vaccination. Titer tests, in particular, quantify the concentration of antibodies present in the blood, providing information about the strength and duration of immunity. These tests are commonly used to assess immunity to infectious diseases such as measles, mumps, rubella, varicella (chickenpox), hepatitis B, and influenza, among others. Interpretation of immunity detection and titer test results helps healthcare professionals determine an individual's susceptibility to specific infections and may guide decisions regarding vaccination or additional preventive measures. These tests play a crucial role in public health surveillance, outbreak investigation, and the development of immunization strategies aimed at protecting individuals and communities from infectious diseases.
