People who are at risk of contracting hepatitis D, including those who have a history of intravenous drug use, sexual contact with infected individuals, or have received blood transfusions before 1992, may benefit from getting tested for HDV.
When this test is required
The HDV PCR test may be requested by a healthcare provider when a patient has symptoms of liver disease or is known to be at risk for hepatitis D infection. Risk factors for HDV infection include injection drug use, having multiple sexual partners, and being born in or traveling to areas with a high prevalence of HDV.
What the Test Detects
HDV PCR (Hepatitis Delta Virus Polymerase Chain Reaction) is a laboratory test that is used to detect and quantify the amount of HDV RNA in a patient’s blood. HDV is a virus that infects the liver and can cause severe liver disease. This virus is unique in that it requires the presence of the hepatitis B virus (HBV) to replicate and cause disease.
Preparation for the Test
No special preparation is required for the test. However, it is important to inform your healthcare provider about any medications you are taking, as some drugs may interfere with the test results. It is also important to inform your healthcare provider if you have had a recent vaccination or have been exposed to any other infectious diseases, as these factors may affect the results of the test.
Sample Requirements
A blood sample is required for the test. The sample can be collected through a standard blood draw, which involves inserting a needle into a vein in the arm.
Additional Notes
It is important to note that HDV infection can be prevented by receiving the hepatitis B vaccine. Therefore, individuals who are at risk for HDV infection should also receive the hepatitis B vaccine.
