How much does it cost to do nucleic acid detection in Kaifeng lankao county Central Hospital?

A:

According to the requirements of nucleic acid detection in Kaifeng, novel coronavirus nucleic acid detection and novel coronavirus serum antibody detection are needed. The detection of nucleic acid in throat swab was 78. 1 yuan, and the detection of serum antibody in novel coronavirus was 39.9 yuan, 1 18 yuan.

What are the commonly used detection methods for the diagnosis of COVID-19's disease?

A: At present, the commonly used detection methods are virus nucleic acid detection and COVID-19 specific antibody serum detection. Nucleic acid detection is to detect some specific nucleic acid sequences in virus genes, which is a direct detection of viruses. Antibody detection is an indirect detection, that is, detecting human immune response to COVID-19. When the virus invades the human body, the human immune system will produce a large number of immunoglobulins, the most common of which are IgM and IgG.

Can COVID-19's serum specific IgM positive be used as a diagnostic basis?

A: No! Serological detection samples of COVID-19-specific antibodies are easy to obtain, simple and quick to operate, and easy to be carried out at the grass-roots level, which can be used as a primary screening method. However, the diagnosis of COVID-19 needs to be judged by combining nucleic acid detection or dynamic observation of IgM and IgG titers. From the perspective of antibody, the basis of diagnosis must be: specific IgM, IgG antibody double-positivity or IgG antibody from negative to positive, or IgG antibody titer in recovery period is more than 4 times higher than that in acute period.

IgM positive is helpful to clinic. IgM antibody first appeared in the whole process of acute infection, and began to appear 3 ~ 5 days after onset until it disappeared. Positive IgM antibody in COVID-19 only indicates that there may be infection in the near future and can only be used as a means of early screening. False positive results will appear in many clinical situations, such as the existence of rheumatoid factor, complement and other substances in the body, or the long storage time and pollution of specimens.
