Antigen diagnosticum: accurate diagnosis of infectious diseases

Diagnostic antigen is an antigen of microbial origin with precisely established specificity, which is used for serological diagnosis of infectious diseases. Serological diagnosis is a diagnostic method based on the detection of antibodies to the pathogen in the patient’s blood.

Antigen diagnostics are used to detect the presence of antibodies in the patient’s blood, which are formed in response to infection. Antigens are used as markers to detect the presence of a disease pathogen in the patient's body. Antigen diagnosticums are used to diagnose various infectious diseases, such as viral hepatitis, HIV infection, influenza, tuberculosis and others.

Antigen diagnosticums have high sensitivity and specificity, which makes them a very effective tool for diagnosing infectious diseases. The specificity of the antigen diagnosticum means that it detects only a specific antigen that is specific to a specific pathogen. The sensitivity of the antigen diagnostic means that it can detect even small amounts of antigen in a patient's blood sample.

One of the advantages of using antigen diagnostic kits is their speed and simplicity. They can be used to quickly diagnose infectious diseases on site, without the need to send samples to a laboratory for analysis. This allows diagnosis and treatment of the patient to begin faster.

However, it should be noted that antigen diagnostic kits are not always an ideal tool for diagnosing infectious diseases. Sometimes they can give false negative or false positive results. Therefore, if the diagnosis is in doubt, additional tests may be required.

In conclusion, antigen diagnostic kits are an important tool for diagnosing infectious diseases. They have high sensitivity and specificity and can be used for rapid on-site diagnosis. However, it must be remembered that they are not always an ideal tool and can give erroneous results. If necessary, additional tests should be performed to confirm the diagnosis.

Introduction: Antigen diagnosticums are a collective name for various serological reactions aimed at detecting pathogenic agents of infectious diseases in blood serum. The antigenic properties of erythrocyte diagnosticums are associated with the presence of special haptens on their surface - antigens present on the surface of cells of the immune system and performing the function of specific binding to antibodies produced during the immune response
