Antigen
Unilabs performs the rapid detection COVID-19 Antigen test to further combat the pandemic.
The antigen test is one of three methods of testing Covid-19. This test makes it possible to identify the presence of specific proteins of the SARS-CoV-2 virus.
- MAIN ADVANTAGES
The main benefits of this test are the speed, simplicity of the process.
This test does not require complex equipment and results are ready in about 20-30 minutes, with delivery in up to 4 hours.
Infected people can quickly be identified and isolated.
- MAIN LIMITATIONS
The antigen test is currently less sensitive than the PCR tests, considered “gold standard” by the WHO and DGS.
These tests work best with high viral loads, within 1 to 5 days of the onset of first symptoms.
Although false positives are rare, patients with low viral loads may experience false negatives.
The test may not detect early asymptomatic and mildly infected patients. In both cases, the patient can infect other people. In this sense, all negative results have to be reviewed by a health professional in order to assess the need for a second test using the PCR method.
We also carry out corporate agreements with companies that need COVID-19 diagnostic tests for their employees. In these cases, to obtain a proposal, you can contact us via email: suporte.covid19@unilabs.pt
