RT-PCR Laboratory Testing
- Results by email, next working day
- Most accurate method of determining current infection
- Fit to Fly certificate available
- Optimal results from 5 to 21 days post exposure to infection
Using Polymerase Chain Reaction (PCR) technologies, PCR kits detect the genetic RNA material of the virus confirming current infection status.
RT-PCR Laboratory testing is the most reliable method of determining an individuals’ infection by the Coronavirus. It uses DNA testing to identify the viral DNA within the individuals’ body and, like all Anti-Gen testing, is most effective in the first 21 days after initial exposure – the period when the level of the virus in the body is at it’s peak. After 21 days, the antibodies developed by the infected person start to fight the virus and eliminate it from the body. Use for:
- Confirmation of a Positive Screening Result
- When individual is Symptomatic
- Following contact with a known infectious person
- International Travel
RT-PCR is highly accurate – it is able to detect very low levels of infection, and is the standard testing method used for determining infection. It is relatively expensive, and the delay incurred by sending the samples to the laboratory mean that it is far less practical than LFIA rapid testing as a screening method, but it should always be used to confirm any positive rapid-screening results.
RT-PCR cannot however determine the level of infection (it’s just a black-and-white, yes-or-no as to whether the viral DNA is present or not), nor can it detect whether an individual has been infected in the past – for this, an antibody test would be required – either an LFIA rapid test, or an ELISA laboratory test using a blood sample.
