This method, which has already been deployed in low-resource settings, is gaining more attention as a way to give more mileage to limited testing supplies, because it can rule out the need to test many people individually. It works best in areas with low prevalence of the virus. Subscribe to Podcast. Skip to main content. Published November 02, By Annalies Winny. Types of Diagnostic Tests There are two main types of diagnostic tests: Molecular tests are the most accurate but usually are performed by lab technicians.
Method: Nasal or throat swab, and for some tests, saliva Turnaround: Varies by type of test Most testing sites use polymerase chain reaction PCR tests , which are very accurate but are usually performed in large certified labs and require skilled lab workers.
Results can take several days to come back. These tests can also be used outside traditional health care settings, and they are quickly becoming more widespread. Antigen Tests What they do: These rapid tests, which detect certain proteins on the surface or in the virus, are inexpensive, efficient, and fast. Method: Nasal or throat swab Turnaround: As fast as 10—15 minutes, or up to 30 minutes Accuracy: False positive results are fairly unlikely with these tests when used as described above, but if you have symptoms and receive a negative antigen test result, you may still have COVID and may need a molecular test for confirmation.
The swab is kept in place for several seconds before it is gently rotated as it is pulled out, and is sealed in a tube to be sent to a lab for analysis.

The different analyses were processed in a double-blind way. The test includes 2 genes N and Orf1b Three primers per gene were used as follows:. The Idylla platform located in the laboratory of clinical and experimental pathology is accredited according to the ISO norm for molecular biology www.
A positive result requires at least 2 N amplified targets [by setting a cut-off on Since Orf1b is highly specific, no cut-off was required for this gene. Baseline characteristics between patients with or without COVID were compared using the Student t -test or Wilcoxon-Mann Whitney test for quantitative variables depending on the normality of distribution of the parameters, or the chi-square test for qualitative variables.
The study was conducted in accordance with the Declaration of Helsinki as revised in The study is registered at ClinicalTrial.

Unlike traditional swab tests, our care team is able to swab and get results back on the same day. A standard test is likely to take a few days to finalize results. Rapid testing allows our care team to get results back to patients on the same day after testing is completed. Usually, patients that are remaining in their local neighborhoods for work and personal activities benefit from same-day rapid antigen COVID testing that can return your results the same day.
