COVID-19 Testing Information

What Is COVID-19 PCR Testing?

COVID-19 PCR (Polymerase Chain Reaction) testing is a molecular diagnostic test used to detect the presence of active SARS-CoV-2 infection.
PCR testing identifies viral genetic material (RNA) using advanced amplification technology that can detect even very small amounts of the virus.

Why PCR Testing Is Considered the Gold Standard

  • Highly accurate and sensitive

  • Detects current, active infection

  • Recommended for individuals with symptoms, recent exposure, or pre-procedure screening

  • Can detect viral RNA even in early stages of infection

How the Test Works

  1. A nasal or nasopharyngeal swab is collected from the patient.

  2. The sample is processed in a laboratory using PCR technology.

  3. Results determine if viral genetic material is present.

What a Positive Result Means: Current COVID-19 infection.
What a Negative Result Means: No viral RNA detected at the time of testing.


What Is COVID-19 Serology IgG Testing?

COVID-19 Serology IgG testing is a blood test that detects IgG antibodies produced by the immune system in response to past SARS-CoV-2 infection or vaccination.

What IgG Testing Tells You

  • Indicates previous exposure to COVID-19

  • Shows whether long-term antibodies are present

  • Helps determine immune response after infection or vaccination (not a measure of immunity level)

How the Test Works

  1. A blood sample is collected.

  2. The sample is analyzed for the presence of SARS-CoV-2 IgG antibodies.

  3. Results show whether your immune system has produced lasting antibodies.

What a Positive Result Means: IgG antibodies detected — likely past infection or immune response to vaccination.
What a Negative Result Means: No detectable IgG antibodies at this time.
