Now, if the in theory, if you have too many particles already present in the patient specimen, the platform doesn't need to do too many cycles to be able to detect the presence of these viral particles 15 2025 cycles are enough to generate signals first and signals for that platform to capture the positive the signals and say this is a positive sample. However, if you are unable to collect enough lorrison signals by doing 20 or 25 or 30 cycles, it will continue up to 40 cycles and if you detect Any positivity in terms of any signatures that you capture for up to 40 cycles, they will tell you that in our platform that we have submitted approval from the FDA up to 40 cycles has been approved to detect enough cinamon fluorescent signal from this patient specimen to call it positive for coronavirus. So the theory is if we detect the viral particles at lower cytokines, that means the PCR did not, did not have to work hard to find these viral particles to be able to call it positive. It's It's It's available, plentiful. However, if the platform needs to go and do more cycles, that's a reflection of a viral load. However, it doesn't really matter at the end of the day, Whether it's positive because of a viral load or low viral load, there is some implications for contagiousness for infection control. But a positive result is a positive finding, and it has to be acted upon accordingly. Now, some platforms said that in our in our validation studies, we consider anything after the cycle 37 in our findings to be negative, meaning that, you know, we keep doing the cycles up until cycle number 37. Above that, you know, for us, we determined that the specimen should be declared negative. And as such, that's where they got the FDA authorization on or approval on other assays including the CDC, for example. It's, they say 40 cycles for us is because To be the cutoff cycle, above that, it's negative below that, we declare the specimen negative. Now, the the difference between polymerase chain reaction and the actual culture is that the polymerase chain reaction will pick that or live organisms. Culture on the other hand, if I have if I have to culture bacteria or viruses in the proper culturing modes, whatever grows is alive particles. If I have dead particles in the patient's specimen, they will not be able to grow. If I am doing a PCR the PCR is not looking for a live agent particles so dead particles will still be amplified will be detected as positive material in the patient's specimen. So that's a fundamental difference between a PCR testing methodology and a culture based methodology. Obviously, for viruses, because of the difficulty in doing culture, the vast majority of labs around the nation are dependent on PCR, some some major reference labs, including the CDC, would still use culturing for for the purposes of, you know, other other reasons that that needed catch up. methodologist.
