Ms. Hong, who lives in Beijing, said: "Everyone says that the red color in my T area is too dark. Will this be related to the severity of the disease? I am quite scared."
Recently, the behavior of "sunlighting" has gradually become popular on social media, and more and more people infected with the new coronavirus choose to post their positive antigen test results in the WeChat group and circle of friends. However, many netizens also found that they are also "yang". Some people's antigen detection reagent T area is dark red, while others are a light red.
According to the instructions of a certain brand of antigen detection kit ( colloidal gold method ), the reporter carefully read it and found that in the column "Explanation of Test Results", it is indeed mentioned that the bands in the detection area (T) can be dark or shallow, but as long as two red bands appear, one is located in the quality control area (C) and the other is located in the detection area (T), then the bands in the detection area (T) are both dark or shallow, are positive.

So, what exactly causes detectors who are also positive for antigens to have different colors of stripes in the detection area (T)? The reporter called a new crown antigen detection reagent manufacturer, Nanjing Novezan Biotechnology Co., Ltd. , as a consumer. The company's engineer called back to the reporter and said that the color depth of the strip can indeed reflect the viral load in the body , that is, the deeper the redness of the detection area (T), the higher the viral load in the body. Not only that, the engineer also added to the reporter: "Even the same user, in the early stage of the onset, the band color of the detection area (T) tends to be darker, and will become lighter in the later stage."
. At the beginning of the article, Ms. Hong was worried that the red darkness of her detection area (T) was a very serious manifestation of the condition. Chen Xin, director of the Second Department of Health Care Department of the China-Japan Friendship Hospital, said that there is no need to worry like this: "The darkness of the antigen detection color is only related to the virus and cannot reflect the condition."
