[0002] During the nucleic acid test, the tester asks the person being tested to open his mouth, and then wipes the secretions from the back wall of the mouth and the tonsils on both sides with a pharyngeal swab. The pharyngeal swab is then placed in a test tube, the tube cap is screwed on tightly, and the tube is sent for testing as soon as possible under low temperature storage. Nucleic acid testing is a clinical etiology diagnosis made under laboratory conditions by analyzing the DNA or RNA genetic sequence of pathogenic microorganisms. This type of nucleic acid testing method uses PCR amplification for testing.

[0003] Traditional nucleic acid collection storage boxes often consist of two placement areas, one for placing nucleic acid barcodes and the other for storing nucleic acid collection tubes.
