What does one deep and one shallow antigen test mean?

The depth antigen test represents a weak positive.

1, weakly positive:

Novel coronavirus antigen test needs to take samples by nasal swab. After sampling, the sampling head will be fully mixed with the sampling liquid, and the sampling liquid will be dripped into the sample card hole to interpret the results. On the kit, we can generally see two letters, namely C and T. If both C and T areas are displayed, one deep and one shallow generally represents weak positive.

2. Improper operation:

For those who use novel coronavirus antigen test for the first time, improper operation will also lead to inaccurate results, resulting in the situation that novel coronavirus antigen test is one deep and one shallow. If it is caused by improper operation, it is recommended to review it every half hour.

? Precautions before testing:

1, preventing infection

When queuing for nucleic acid testing, you should wear a mask, keep a queue distance of at least one meter from others, avoid too much communication and contact with others, and do your own protection to prevent infection.

2. Keep your mouth and nose clean.

Try to avoid drinking, smoking, brushing teeth and chewing gum within half an hour before nucleic acid detection, and keep the oral cavity and nasal cavity clean to prevent the effect of nucleic acid detection from being affected.

Try not to eat for two hours.

Swallow swab may be used for nucleic acid detection, which will further stimulate the human pharynx and easily lead to nausea. Therefore, within two hours before nucleic acid detection, you should try to avoid eating and prevent vomiting.
