What This Test Measures

The test detects specific RNA sequences from coronaviruses using molecular probes. These probes bind to unique genetic fragments of the virus if present in your sample, allowing for identification. This is often done through advanced laboratory techniques like polymerase chain reaction (PCR).

How the Test Works

Your sample (likely collected from a nasal or throat swab) is analyzed to identify viral RNA fragments. If the virus is present, the probes will bind to these fragments, triggering a detectable signal that confirms exposure. This process helps differentiate between different coronaviruses.

Why It’s Done

Healthcare providers may order this test to diagnose COVID-19 or other coronavirus infections, monitor exposure risks, or assess potential outbreaks in certain settings.

Sample Collection

A healthcare professional will collect a sample, typically a nasal or throat swab. The sample is then sent to a lab for analysis. This test does not require fasting or special preparation.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

This test is primarily used to detect the presence of coronavirus RNA, which can indicate recent infection. It is not a test for antibodies or active illness but is critical for early identification of exposure, especially in high-risk or outbreak settings.
This test can help determine if you’ve been exposed to a coronavirus, which may be important for public health monitoring or guiding treatment decisions.
What does a positive result mean?
A positive result suggests that coronavirus genetic material was found in your sample, meaning you may have been exposed to the virus. However, this does not always mean you are currently sick. Further testing or clinical evaluation may be needed to confirm infection or symptoms.
How long does it take to get results?
Results are typically available within 24 to 72 hours, depending on lab processing times. Your healthcare provider will discuss the results with you.
