These self-test boxes.
Mostly usedColloidal gold, immunochromatography
to test for Mycoplasma pneumoniae.
Types can be divided into two types.
Antibody test and IgM antigen test
Antibody tests generally require self-sampling of blood and drops of blood on a test card;
The IgM antigen test is done by a "nasal and throat swab."It is detected by the mucosal epidermis of the oral cavity and nasal cavity.
However, doctors said that the detection of Mycoplasma pneumoniae has high requirements for operation methods, sampling locations, disease stages, etc., and there are also uncertainties in the accuracy and sensitivity of the detectionPeople who are in the window of infection may test negative, and a positive test may be due to a previous infection.
If the test is wrong, there is a risk of delaying the disease, so the doctor said that the two methods of Mycoplasma pneumoniae self-test are not recommended.
Even if there is no antigen
We can also judge ourselves from the symptoms
"Initial screening" of the first stream to do so
1.Look at the fever.
The common cold is generally a low-to-moderate fever;
After being infected with influenza A, the fever is usually more pronounced, often high.
2.Listen for coughing.
The common cold is an occasional cough;
The cough is relatively severe after influenza A infection.
3.Look at respiratory symptoms.
The symptoms of the common cold are mostly nasal congestion, runny nose, sneezing, etc.;
The upper respiratory tract symptoms of influenza A infection can be more "mild".
4.Presence or absence of constitutional symptoms.
Systemic symptoms of the common cold are not obvious;
After infection, it is often accompanied by systemic symptoms such as muscle pain, headache, and fatigue.
5.Look at the course of the disease.
Both the common cold and influenza A are self-limiting diseases, and the differences are:
The common cold has a short course of illness and usually heals spontaneously in 3 to 5 days;
Most of the influenza A can gradually reduce fever after 3 to 5 days of onset, and it takes 1 to 2 weeks for cough and physical strength to recover.
6.Whether there are complications.
Influenza A infection can be combined with otitis media, pneumonia, myocarditis, encephalitis, etc.;
The common cold rarely causes these conditions.
