COVIPROTECT gives you exact measurement of the antibody titres available in your body against Spike Protein either post vaccination or post infection of COVID 19. The spike protein antibodies are generally developed after 2 weeks of second dose of vaccination or 4 weeks of exposure to infection. Having said that, certain individuals developed Spike protein antibodies even after first vaccine dose itself.
On the other hand, Qualitative Test gives you an idea whether Antibodies are present or absent without the actual titre. Its use is limited in knowing the exposure status than to the actual titre. With advent of COVIPROTECT, it is likely that the qualitative test would become obsolete soon.
