Hepatitis-related Diagnostic Tests

Hepatitis-related Diagnostic Tests

Hepatitis refers to an inflammatory disease of the liver. The condition is commonly caused by a viral infection, but there are other possible causes of Hepatitis. These include autoimmune Hepatitis that occurs as a secondary result of toxins, drugs, alcohol and medications. Autoimmune Hepatitis is a disease that occurs when the body produces antibodies against the liver tissue.

Hepatitis testing

A hepatitis panel is blood tests that check to see if you have a hepatitis infection caused by one of these viruses. There are different hepatitis panels. Some tests look for proteins (antibodies) that the body makes to fight the infection. Other tests look for antigens or the genetic material (DNA or RNA) of the viruses that cause Hepatitis.

Who needs hepatitis testing?

Individuals may require a test if they have symptoms of liver damage. These symptoms include:

  • Fever
  • Fatigue
  • Loss of appetite
  • Jaundice (yellowing of the skin and eyes)
  • Dark-coloured urine
  • Pale-coloured stool
  • Nausea and vomiting

Those with certain risk factors may need testing, including people who:

  • Have been in close contact with someone infected with Hepatitis
  • Are on long-term dialysis
  • Use illegal, injectable drugs
  • Have a sexually transmitted disease

What are the different types of Hepatitis?

There are many types of Hepatitis, but the three most common are:

Hepatitis A

Hepatitis A is mainly transmitted by consuming water or food contaminated by the stool of a person infected with Hepatitis A.

Hepatitis B

Hepatitis B is transmitted via contact with infectious body fluids, such as blood, semen or vaginal secretions that contain the hepatitis B virus. Injection drug use, unprotected sex, or sharing razors with an infected person increases the risk of contracting hepatitis B. For some people, hepatitis B infection can become chronic. 

Hepatitis C

Like Hepatitis B, Hepatitis C is contracted via direct contact with infected body fluids, typically through injection drug use and unprotected sex.
