Introduction

A serum antibody test is a blood test that is pivotal in diagnosing and managing various infectious diseases, immune system disorders, and for epidemiological investigations. This article provides detailed insights into what these tests detect, along with a highlight of solutions offered by Joinstar, a leading company in the diagnostics field.

What Does a Serum Antibody Test Detect?

Serum antibody tests are designed to detect specific antibodies, which are proteins produced by the immune system in response to antigens, such as viruses, bacteria, and other pathogens. These tests can be categorized based on the type of antibodies detected:

  • IgM Antibodies: Typically, the first antibodies to appear after an infection. Their presence indicates recent or active infection.
  • IgG Antibodies: These antibodies usually develop later and can indicate past infection or vaccination. IgG levels can provide insights into immunity status over time.

Specific numerical parameters include:

  • Sensitivity and Specificity Rates: Many tests aim for a sensitivity and specificity greater than 95% to ensure reliable results.
  • Concentration Levels: Antibody concentrations are often measured in units per milliliter (U/mL), with thresholds for positivity varying by test and pathogen.

Serum antibody tests are crucial in diagnosing diseases such as HIV, Hepatitis B and C, COVID-19, and more. They also play a role in evaluating vaccine efficacy by measuring antibody response post-vaccination.
