Going with a child for a serological test of blood, it is important to know that tests pass on an empty stomach.

On the day before the test, it is recommended to avoid sweet and fatty foods, not to overeat, and also to avoid excessive physical exertion. All these factors can distort the results. If there is a study on viral hepatitis, a day or two before the analysis should be avoided brightly colored fruits and vegetables.

For analysis, blood serum is used, to which antigens or antibodies are added. According to the chemical reaction, it is concluded whether there is a disease. Blood is taken from a vein.

In order to confirm the infection and the active infectious process, the analysis is repeated and the extent to which the amount of antibodies has increased is evaluated.
