RT-PCR Vs SARS-CoV-2 IgM Ab Rapid Test
Comparative Test Summary
In this trial, 1300 clinical samples were selected. There were 300 positive samples and 1000 negative samples.
The SARS-CoV-2 IgM Ab rapid test and the SARS-CoV-2 RT-PCR test were detected simultaneously and the Sensitivity (positive coincidence rate), Specificity (negative coincidence rate), and Accuracy (total coincidence rate) were calculated:
Antibody | Sensitivity | Specifity | Accuracy |
IgG | 93% | 97.5% | 96.5% |
IGM | 92% | 96% | 95.8% |

DIAGNOSTIC PROCESS
It is widely accepted that IgM provides the first line of defence during viral infections, followed by the generation of adaptive, high anity IgG responses for long term immunity and immunological memory. Therefore testing of COVID-19 IgM and IgG antibodies is an efective method for the rapid diagnosis of COVID-19 infection. Furthermore, detection of COVID-19 IgM antibodies tends to indicate a recent exposure to COVID-19, whereas detection of COVID-19 IgG antibodies indicates a later stage of infection. Thus, this combined antibody test could also provide information on the stage of infection.
SPRING HEALTH DIAGNOSTIC APPLICATION
Spring Health has developed a disruptive mobile solution to capture diagnostic immediately and for analytics. The globally scalable end-to end solution has proven to be a powerful product and service.Spring Health Infectious Diseases Reader is a solution for healthcare professionals in Point of Care diagnostics for COVID-19. The Spring Health solution consists of a smartphone mobile reader application and a backend solution.The smart phone mobile reader application is used to digitize and analyse lateral flow tests, while the backend solution provides analysis, support and dynamic configuration for the supported lateral flow tests. With very minimal instructions even to untrained staff, the solution can be deployed to capture digitized diagnostic data. The data can be verified and analysed in 3 simple steps:
BENEFITS
* Immediate diagnostics without costly hardware setups – only a smartphone is necessary
* Web applications in the Secure Cloud ensure real-time medical guidance back to the mobile application user
* No attachments – no additional hardware – no additional trainings or wires are required
* Seamless data management integration into client / stakeholder information systems
* Disease surveillance and real time epidemic alerts via interactive mapping
