Biological detection cartridge and method for performing the same

A method for performing a biological detection cartridge, comprising steps of:

• (a) providing the biological detection cartridge, wherein the biological detection cartridge comprises a sample chamber having a port, a plurality of culture chambers for incubating a sample therein, a channel system configured to deliver the sample into each of the culture chambers, a plurality of quantitative chambers, and a plurality of concave structures, wherein the channel system comprises a curved channel and a plurality of inlet channels, the curved channel is communicated with the sample chamber, and each of the inlet channels is communicated with the curved channel and a corresponding one of the culture chambers, wherein each of the quantitative chambers is disposed between a corresponding one of the inlet channels and a corresponding one of the culture chambers, wherein each of the concave structures is disposed between a corresponding one of the quantitative chambers and a corresponding one of the culture chambers, wherein the concave structure comprises a first hole disposed close to the culture chamber;
• (b) inclining the biological detection cartridge to have the sample chamber higher than the channel system, and loading the sample through the port, so that the sample flows into the curved channel and each of the inlet channels and the quantitative chambers;
• and
• (c) vertically placing the biological detection cartridge, so that the sample flows down to the culture chambers.
