So what is immunoglobulin? We can generally think that "immunoglobulin ≈ antibody" is the main substance that produces immune response to foreign antigens (such as bacteria, viruses and other toxins or foreign bodies). Antibodies are specific when binding to antigens, that is, antibodies can bind to one or more antigens very effectively and closely. Because of this characteristic, antibodies play an important role in the process of human immune defense.
First of all, the effect of gamma globulin in the treatment of infection in COVID-19 is still controversial. Some friends injected COVID-19 in advance to "prevent" it, which may bring health risks and the risk of blood-borne diseases.
Secondly, you can pay attention to these diagnosis and treatment projects. More than one word "heavy" can be found in almost all the contents related to gamma balls, such as "severe or critical patients" and "severe X disease". This is because there is no high-quality study on the therapeutic effect of gamma globulin on COVID-19 infection. Based on past experience, some medical teams should try and try to minimize patients' critical illness and death.
Gamma sphere is an antibody extracted from the plasma of healthy people. However, coronavirus pneumonia-19 human immunoglobulin was obtained from the plasma of a large number of convalescent blood donors infected with COVID-19. It belongs to COVID-19 specific antibody, which is different from γ-sphere. Injecting coronavirus pneumonia-19 immunoglobulin in an emergency can really have a good effect. However, this should also be judged by doctors. It should be used in patients with high risk factors, rapid disease progression and high viral load, and should not be used at will.
