Hepatitis E Virus by Quantitative PCR
Also known as: HEV QNT
Use
This test is used to confirm and quantify the presence of the hepatitis E virus in a patient's specimen. It aids in monitoring viral load and assessing the infection status of individuals suspected of having hepatitis E. The quantitative results can assist clinicians in determining the severity of the infection and in making treatment decisions for managing hepatitis E, particularly important in monitoring immunocompromised patients or those with chronic liver disease.
Special Instructions
Not provided.
Limitations
A negative result does not rule out the presence of PCR inhibitors in the patient specimen or HEV RNA concentrations below the level of detection of the test. Inhibition may lead to an underestimation of viral quantitation. The test's quantitative range is 3.3-8.3 log IU/mL, with one IU/mL equating to approximately 2.25 copies/mL. The test is a Laboratory Developed Test (LDT) and is not FDA cleared or approved.
