Recently, the first thing many people do when they wake up in the morning is:
Swallow your saliva to see if your throat hurts;
Touch your forehead to see if you have a fever;
Take a deep breath to see if your nose is blocked;
Also,
take out an antigen kit and
see if you have become a "squadron leader."
Compared with nucleic acid detection , antigen detection is faster and the operation is more convenient. What do the C and T on the
Q
kit mean? There are three English letters on the
antigen kit, namely C, T and S. What do these three English letters mean?
C (Control Line), which is the "control line";
T (Test Line), which is the "test line";
S (Sample Hole), which is the "sample area".
If only one red bar appears at C, the antigen is negative; if red bars appear at both C and T, that is, two red bars appear, regardless of the color, the antigen is positive; if a white board appears (no red bar appears), or only one red bar appears at T, it means that the test was unsuccessful and invalid, and the test must be repeated.
Q
The darker the color of the T area, the more serious the condition? According to the
antigen test results, some people have a shallow red line in their T-zone, while in some people the " positive line " in the T-zone is red, purple or even black. The deeper the "yang line" is, the more serious the condition is, right?
Theoretically, the depth of the strip color can reflect the viral load in the sample being tested. However, different people, different sampling locations, methods, and different sampling periods will all affect the amount of virus collected.
For example, the amount of virus in your body may be higher, but due to irregular sampling or other reasons, the amount collected is relatively small, and the "positive line" may be relatively shallow.
For the same patient, the color of the T line reflects the viral load to a certain extent. The darker the color, the higher the viral load.
Q
What is the Ct value of nucleic acid detection?
The "Novel Coronavirus Pneumonia Prevention and Control Plan (Tenth Edition)" states that home isolation treatment can be terminated if the Ct value is ≥35 for two consecutive times. What is the value of
Ct? Is the
Ct value related to the C and T on the antigen kit?
Ct value
The "Ct value" of nucleic acid detection is actually the cycle number threshold (Cyclethreshold). It has nothing to do with the CT on the antigen detection reagent. If the virus concentration in the
sample is not high, it will be difficult to observe, so we must find a way to increase the concentration of the virus. How to increase the concentration? This method of
is called PCR: polymerase chain reaction (Polymerase Chain Reaction). Viral nucleic acid can be amplified through PCR.
The larger the Ct value, the smaller the virus content, and the weaker the infectivity; the smaller the Ct value, the larger the virus content, and the stronger the infectivity.
In other words, the Ct value is inversely proportional to the virus content and infectivity. The higher the CT value, the safer it is.
Q
There are more positive people around. How to adjust your mentality?
There are more and more positive people around, and everyone will inevitably feel a little anxious. Excessive anxiety will seriously affect our lives, causing us to pay more attention to small changes in the body, associate various discomforts with related symptoms, always feel that we are "yang" and become anxious and suspicious; we can't help but wash our hands and sanitize repeatedly, and even become haggard and uneasy.
When we are worried about whether we will be "yang", we might as well take a few minutes of deep breathing to shift our attention to specific things that are currently controllable, protect ourselves, and improve our self-control, so as to relieve "anxiety".
When facing whether it is "yang"
We don't have to be overly anxious
When symptoms appear
Prescribe the right medicine immediately, rest and observe
If no symptoms occur
We must protect ourselves
