Types Of Covid-19 Testing


 

There are two types of tests available for the Novel Sars-Cov-2, also known as COVID-19, infection: 

  1. PCR testing: Nasal Swab
  2. Antibody testing: Blood test

PCR Testing:

This type of testing is used to detect active infections through PCR (polymerase chain reaction) testing methodology where a swab is obtained from the nasal passageway.  This is the common test performed on individuals who show symptoms or have been exposed to someone with an active infection.

Antibody Testing:

This type of testing is used to detect past infection or exposure to the virus.  This is a blood test which checks for a type of antibody called immunoglobulin G (IgG) that is the result of past or recent exposure to COVID-19. The antibody test is not a test for an active infection. The human body produces IgG antibodies as part of the immune response to the virus. It usually takes around 10 to 18 days to produce enough antibodies to be detected in the blood.

Current studies show that close to 100% of the people develop IGG antibody against the Covid-19 virus after 15 days of exposure.

At this time it is unclear whether a patient who has an IGG antibody against Covid-19 is considered to be “immune” against future or re-infection.

Pandya Medical Center offers both nasal swab PCR testing and blood Antibody testing at all of its locations.  Please call the office to speak to a staff member to schedule an appointment 770-709-6922
