Method for identifying anti-Toxocara IgG marker in blood serum

摘要

The invention relates to medicine, namely to a method for identifying anti-Toxocara IgG marker in blood serum and can be used for diagnosing human toxocariasis.Summary of the invention consists in the study of blood serum in an immunoenzyme test using a microplate with adsorbed Ag toxocara canis and determining the optical density values of the samples by the photometric method at a wavelength of 450 nm, then determining the ratio of the average optical density of the patient's serum x 10 and the average optical density of the negative control samples, and if the ratio is up to 9 NTU, it is considered that the result is negative, if it is greater than 11 NTU, the result is positive, and samples with the result of 9…11 NTU are treated with 25% kaolin suspension, then is repeated the immunoenzyme test with subsequent determination of the indicated ratio to determine the negative result if the ratio is up to 9 NTU and positive if it is greater than 11 NTU.
