What Does This Test Measure?

The test uses advanced sequencing technology to identify and quantify viral RNA fragments present in your serum or plasma. It can detect a wide range of viruses, including those causing infections like hepatitis, influenza, or other respiratory or systemic illnesses. The probe specifically targets viral genetic material, allowing for precise identification.

Why Might You Need This Test?

This test may be recommended if you have symptoms of infection (e.g., fever, fatigue, flu-like illness) and your doctor suspects a viral cause. It can also be used in research, monitoring, or screening contexts where viral RNA detection is critical.

How Is the Sample Collected?

A blood sample is drawn from a vein, typically in your arm. The blood is processed to separate serum or plasma, which is then analyzed for viral RNA. This process is similar to standard blood draws but involves specialized techniques for RNA extraction and sequencing.

What Are Possible Results?

Results may indicate the presence of specific viral RNA sequences, suggesting an active viral infection. Negative results mean no detectable viral RNA was found in this sample. Interpretation depends on clinical context, symptoms, and other diagnostic findings.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

How does this test help doctors?
This test helps doctors confirm or rule out viral infections that may not be detected by other blood tests, such as antibody tests. Early detection can guide treatment decisions, monitor disease progression, or assess response to therapy.
How does this differ from antibody tests?
Unlike antibody tests, which detect immune responses to past or current infections, this test directly measures viral RNA. It can detect infections at earlier stages, even before antibodies develop, making it useful for acute or early-stage viral infections.
What if I have a positive result?
A positive result suggests active viral infection. Your healthcare provider will discuss next steps, which may include further testing, treatment recommendations, or monitoring based on the specific virus detected.
