Testing for novel coronavirus or COVID-19 might take from a couple of hours to minutes to give you results. However, the procedure of sample-taking lasts for a few seconds, no matter what test you choose to perform to yourself. In this article, we will go through the available testing methods, and the estimated time it takes for each one to give results.
The three methods to test for SARS-Cov-2 are the following:
- Swab samples and laboratory PCR tests
- Blood samples and laboratory antibody tests
- Fingerstick blood samples and COVID-19 rapid kit tests
All these COVID-19 testing methods are only for healthcare professional use. Experts do not recommend getting tested alone for the novel coronavirus.
How long does it take for a PCR test to give you COVID-19 results?
A polymerase chain reaction (PCR) is a lab technique based on the genetic material of the virus. It compares your sample to the SARS-Cov-2 virus through a reverse transcription-polymerase chain reaction. It does so by targeting 100 specific nucleotides that include two genes. To get tested for COVID-19 using a PCR technique, your doctor takes a swab sample from your upper respiratory system, such as your throat. This procedure might take a few seconds up to a minute. PCR is a classical technique that uses antigen testing takes a few hours to give you results. Due to lots of patients getting tested daily, it might take up to two days for an individual to receive their results and follow the relative measures.
How long does it take for a serological antibody test to give you COVID-19 results?
A serological antibody test detects the presence or the absence of SARS-Cov-2 based on a person's antibodies. They work on blood samples that a doctor collects using a syringe. These tests establish whether you have or had SARS-Cov-2 infection in the past. However, human antibodies formed against a virus may take days to appear in the blood serum, making early infections underdiagnosed. These tests also require a few hours to give COVID-19 results. Due to the large daily workload in the labs, it might take days for an individual to receive their results. Meanwhile, there is the danger of disease transmission to others, in the case of a COVID-19-positive individual. ELISA is one of the most common methods to detect blood serum antibodies.
How long does it take for a fingerstick rapid test kit to give you COVID-19 results?
Rapid test kits for novel coronavirus also detect blood serum antibodies. However, they do so way faster. According to Eleanor Riley, professor of immunology at the University of Edinburgh, rapid test kits "use proteins from the SARS-Cov-2 as “glue” to trap antibodies present in the blood". Test kits for COVID-19 need to detect two types of antibodies. The first one is IgM, and the second one is IgG. IgM is the first one to develop during an infection, and the first one to fight it. IgG appears later in the course of the disease to provide memory and immunity. It takes just a few minutes for fingerstick rapid test kits to give you COVID-19 results.
