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
-
A nasal or nasopharyngeal swab is collected from the patient.
-
The sample is processed in a laboratory using PCR technology.
-
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
-
A blood sample is collected.
-
The sample is analyzed for the presence of SARS-CoV-2 IgG antibodies.
-
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.
