Flowflex™ SARS-CoV-2

Antigen Rapid Test

Fast. Easy. Simple.

Flowflex SARS-CoV-2 Antigen Rapid Test is a lateral flow chromatographic immunoassay for the qualitative detection the nucleocapsid protein antigen from SARS-CoV-2 in nasal and nasopharyngeal swab specimens.

  • Nasal and Nasopharyngeal swab specimens
  • Results in 15 minutes
  • Excellent performance compared to molecular methods
  • Room temperature storage

The Flowflex SARS-CoV-2 Antigen Rapid Test is authorised for use in Singapore by the Health Science Authority (HSA) under the Pandemic Special Access Route (PSAR) and Pre-Market Approval (PMA). The test does not require skilled professional or equipment to interpret the test results. Suitable for home and office use.

How Does the Flowflex™ SARS-CoV-2 Antigen Rapid Test Work?

The test uses a swab specimen to determine a positive or negative COVID-19 result. The swab is swirled in a tube of solution before being dropped into a test cassette. After ten minutes, you can see your results.

Here’s a quick overview of how it works:
Before you begin the test, it’s important to first read and closely follow the detailed instructions, included in the package.

On September 2021, the Flowflex became the second COVID-19 Antigen Rapid Test that been issued Pre Market Approval (PMA) after the SD Biosensor Standard Q. Since November 2021, the Flowflex has also approved under the PSAR.

5The SARS-CoV-2 Antigen Rapid Test is a lateral flow chromatographic immunoassay for the qualitative detection the nucleocapsid protein antigen from SARS-CoV-2 in nasal and nasopharyngeal swab specimens directly from individuals who are suspected of COVID-19 by their healthcare provider within the first seven days of the onset of symptoms. 

Under the PMA, the test is authorized for supply to the healthcare institutions, private hospitals, medical clinics or clinical laboratories licensed under the PHMC Act (Cap. 248). This test may also be supplied to ship vessels and be exported out of Singapore subject to the duties and obligations as stipulated in the Health Products Act and the Health Products (Medical Devices) Regulation 2010.

Under the PSAR, the test is authorized for use by layman for self testing in Singapore. Suitable for use at home, office, workplace, etc.


Omicron Variant update (29th Nov 2021)

Computer simulations known as silico have been conducted and we do not expect any negative impact of the Omicron on the performance of the FlowFlex. MOH has received our in silico analysis report. Download the report here

There is no obvious difference observed when testing with different nucleocapsid protein recombination antigens (Alpha, Beta, Gamma, Delta, Epsilon, Zeta, Eta, Theta, lota, Kappa, Lambda, Mu and Delta plus) basing on these different variants of SARS-CoV-2. The Omicron variant, by theoretical analysis of the mutations in the nucleocapsid protein, should not interfere the detection by the  Flowflex SARS-CoV-2 Antigen Rapid Test. So we do not anticipate that these variants, including Omicron, will have any effect on test performance.
