How the Test Works

A small sample of your blood or plasma is taken and analyzed for the presence of viral genetic material. A fluorescent probe binds specifically to viral nucleic acids if they are present, allowing for detection with a sensitive instrument.

What It Measures

The test measures the presence of viral nucleic acids (RNA or DNA) in your sample. If the probe binds to these sequences, it indicates a possible viral infection.

Common Uses

This test may be used to diagnose infections caused by viruses such as influenza, respiratory syncytial virus (RSV), or other pathogens for which nucleic acid testing is indicated.

Preparation

No special preparation is needed for this test. You may eat, drink, or take medications as usual. Blood is typically drawn from a vein in your arm.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

When might I get this test?
You may receive this test if your healthcare provider suspects a viral infection based on symptoms like fever, cough, fatigue, or other signs. It can also be used in research, screening, or monitoring for certain viral diseases.
What does a positive result mean?
A positive result means that viral genetic material was detected in your sample. This suggests the presence of an active viral infection, but further testing or clinical correlation may be needed to determine the specific virus and appropriate treatment.
Are there any risks or side effects?
The most common side effect is a slight bruise or soreness at the needle insertion site. Rarely, there may be mild swelling or redness. Blood tests are generally safe, but always discuss any concerns with your healthcare provider.
