Why HAV Antibody (IgM) Test?


Liver is the most important organ that performs a variety of functions for the normal functioning of the body which includes the synthesis of major biomolecules such as enzymes, hormones etc, stores vitamins, sugars and iron to help give the body energy, regulates the metabolites such as cholesterol, clears the metabolic end-products from the blood, synthesis of clotting factors, produces immune factors to combat infections, releases bile for the absorption of fats etc. Hepatitis A Virus (is also known as hep A or HAV) is the most common cause of inflammation to the liver. It causes mild to severe illness. Hepatitis A is spread by eating or drinking contaminated foods and/or water (foodborne viral disease). Hence it is common in places like low-socioeconomic conditions with poor sanitation and hygiene conditions (feco-oral transmission). It can also be spread by unprotected sex, multiple sex partners, sharing needles, travel to endemic places (countries) with hepatitis A, high-density populations (over-crowded populations) etc. clinical manifestations include flu-like symptoms, poor appetite, diarrhea, abdominal pain, dark urine, pale stools, jaundice, itchy skin etc. other clinical manifestations include hepatomegaly, splenomegaly, bradycardia, lymphadenopathy, elevated transaminase enzyme levels, fulminant liver failure, encephalopathy, pancreatitis, aplastic anaemia, Guillain-Barre syndrome, transverse myelitis, tubular necrosis, interstitial nephritis, glomerulonephritis, cryoglobulinemia, reactive arthritis, pleural and/or pericardial effusion etc. IgM is an immunoglobulin subtype mainly found in the blood and the lymph fluid. It is the first class of antibodies to fight a new infection. Hepatitis A diagnosis is performed by the detection of viral hepatitis A viral antigens, antibodies (eg. IgG, IgM etc) against anti-viral hepatitis A virus, PCR, NAAT etc. Positive test result suggests recent or current infection or history of a past infection, assess immunity etc. Additional tests include CMIA for the detection of IgG and IgM antibodies. Other tests include liver function test and liver enzymes to measure potential liver damage (liver inflammation) caused by a hepatitis-B virus (i.e enzyme assays) such as alanine amino-transferase (ALT) elevated during inflammation of the liver, PCR to measure HBV –DNA, fibro scan for transient elastography and aspartate aminotransferase (AST) to platelet ratio for the assessment of liver cirrhosis, ultrasound, liver biopsy etc.
