First, the retractable arm extends, so when the fecal matter sinks to the bottom of the toilet, it comes into contact with the arm. Then, the arm moves back inside the scanner's main body, causing the scraping spikes to drag against the fecal matter. This movement allows a sample of fecal matter to be taken. A sample of the toilet water is also taken and the DNA of the bacteria located in the water is sequenced.
Once the fecal sample is collected, DNA sequencing commences. The fecal sample first goes through DNA extraction and purification. Then, Polymerase Chain Reaction (PCR) is performed on the DNA to amplify it. Next, the DNA gets sequenced based on the 16S ribosomal RNA (16S rRNA). These functions are all performed by a single microfluidic chip. The bacteria classified in the water is subtracted from the bacteria that was classified in the fecal matter sample to avoid contamination.
After the data is processed, the information about the bacteria located in the fecal matter will be sent straight to an app on the user's phone. On the app, all of the health data previously recorded will be stored and made available to the user. Primary care physicians will have direct access to the data and will be able to individually assess when a physical check-up is necessary.
