Real time RT-PCR is a nuclear-derived method for detecting the presence of specific genetic material in any pathogen, including a virus.
Real time RT-PCR is one of the most widely used laboratory methods for detecting the COVID-19 virus. While many countries have used real time RT-PCR for diagnosing other diseases, such as Ebola virus and Zika virus, many need support in adapting this method for the COVID-19 virus, as well as increasing their national testing capacities.
PCR Test is run at a lab and can detect the virus BEFORE you have symptoms and during the entire virus.
Results usually take 24- 48 hours from when the lab receives the swab.
Same day results are available at some locations.
Testing and Air Travel- What test?
Here's what to know:
Get tested with a RT-PCR Test 1-3 days before your flight.
Get tested with a RT-PCR Test 3-5 days after travel AND stay home for 7 days after travel.
Always follow state and local recommendations or requirements related to travel.
Even if you test negative, stay home for the full 7 days.
If you don't get tested, it's safest to stay home for 14 days after travel.
Delay your travel if you are waiting for test results.
Countries and states that require testing prior to entry are mostly using the RT-PCR molecular test (for travel purposes, this isn't covered under insurance).
COVID-19 Antigen Test is a lateral flow immunochromatographic assay for the detection of extracted nucleocapsid protein antigens specific to SARS-CoV-2 in swab specimens directly collected from symptomatic individuals who are suspected of COVID-19 by their healthcare providers
FDA Approved under EUA
10 Minute Turn Around Time
If Negative, PCR Test is recommended
With acute infections in symptomatic patients 88.4% Sensitivity = 12% False Negative Results
With acute infections in symptomatic patients 100% Specificity = 0% False Positive Results
