Insights

Hepatitis C virus (HCV) core antigen tests identify active HCV infections, unlike antibody tests. These antigen tests aid in diagnosing early infections and monitoring treatment effectiveness.

Area of Science:

  • Hepatology
  • Virology
  • Immunology

Background:

  • Hepatitis C virus (HCV) antibody tests are common for detecting exposure.
  • Antibody tests cannot differentiate between resolved and active HCV infections.
  • HCV core antigen tests offer a method to identify active viral replication.

Purpose of the Study:

  • To highlight the utility of HCV core antigen detection in biological fluids.
  • To present HCV core antigen testing as a tool for identifying active HCV infections.
  • To discuss its application in early detection and therapy monitoring.

Main Methods:

  • Review of serological testing methodologies for HCV.
  • Focus on the principles and applications of HCV core antigen assays.
  • Discussion of quantitative HCV core antigen testing.

Main Results:

  • HCV core antigen tests detect active infection, unlike antibody tests.
  • These tests can identify early-stage HCV before antibody development.
  • Quantitative assays enable monitoring of antiviral therapy efficacy.

Conclusions:

  • HCV core antigen testing is valuable for confirming active infection in seropositive individuals.
  • It serves as an early detection method in blood banks and diagnostic labs.
  • Quantitative core antigen tests are crucial for assessing treatment response.

Viral Hepatitis I: Introduction01:28

Viral Hepatitis I: Introduction

Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...

Hepatitis

Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...

Cytomegalovirus Disease

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
Enzyme-Linked Immunosorbent Assay01:33

Enzyme-Linked Immunosorbent Assay

In 1971, Peter Perlman and Eva Engvall developed an Enzyme-linked immunosorbent assay (ELISA or EIA). ELISA differs from western blot in that the assays are conducted in microtiter plates or in vivo rather than on an absorbent membrane.
There are many different types of ELISAs, but they all involve an antibody molecule whose constant region binds an enzyme, leaving the variable region free to bind its specific antigen.  Enzyme-substrate reaction allows the antigen to be visualized or quantified.
Antigens Involved in Adaptive Immunity01:26

Antigens Involved in Adaptive Immunity

An antigen is any substance the immune system identifies as foreign and potentially harmful to the body, prompting an immune response. Antigens have two functional properties: immunogenicity and reactivity. Immunogenicity is the ability of an antigen to stimulate a specific immune response. At the same time, reactivity describes the antigen's ability to react with the cells and antibodies produced in response to it.
Complete Antigens
Complete antigens possess both immunogenicity and reactivity.
Antigen Presenting Cells01:22

Antigen Presenting Cells

The immune system is a complex network of cells and molecules that protects the body from foreign invaders. T cells, a type of white blood cell, play a crucial role in this process. They recognize and attack foreign substances, such as pathogens, that enter the body.
T cells require the help of antigen-presenting cells (APCs), which process foreign antigens into smaller fragments that can be recognized by T cells. These APCs are highly specialized cells that efficiently internalize antigens...
