Coronavirus Testing Kits: FAQs

Some frequently asked questions about the PCR Testing Kits. Please don’t hesitate to contact us if you don’t find the information you are looking for.

What is the difference between the PCR test and an Antibody test?

The PCR test answers the question “Do I have Covid-19?” and an Antibody test answers the question “Has my body shown a IgG antibody response to Covid-19?’. The PCR test is ideal for those who think they may currently have the virus.

When should I use the PCR test?

Use the PCR test if you suspect you currently have Covid-19 or suspect you have recently been exposed to it. The PCR test can detect Covid-19 even if you don’t yet have symptoms.

Does a positive test result mean I am immune from future infection?

No. At present, we do not know if recovering from Covid-19 protects you from reinfection.
According to the World Health Organisation: “There is currently no evidence that people who have recovered from COVID-19 and have antibodies are protected from a second infection.

Is the test reliable?

The PCR test reports high sensitivity and high specificity.

Sensitivity tells you how often a test correctly gives a positive result for people who have the condition being tested for. This is also known as the “true positive” rate.

Specificity tells you how often test correctly generates a negative result for people who do not have the condition being tested for. This is also known as the “true negative” rate.

The PCR test has a specificity of 100% and a sensitivity of 100%
