Determination of the specific markers of acute viral hepatitides A and B (HA and HB) by radioimmunoassay demonstrated that in the structure of acute viral hepatitides in children HA prevails in the interepidemic period (49.4%) followed by HB (19.3%), then by a polyetiological group of acute viral hepatitides of obscure etiology (17.2%), then by HA in the presence of chronic HB (9.7%) and combined acute forms of HA and HB (4.3%).

The study of patients from 10 foci of acute viral hepatitides for the presence of HBsAg (in the passive reverse hemagglutination test) and anti-hepatitis A virus IgM (in the radioimmunoassay) has shown high frequency and variability in the spread of hepatitis non-A, non-B, the prevalence of adults aged 20-29 years and children aged 2-4 years among persons involved into the epidemic process and the tendency towards an increase in the proportion of hepatitis non-A, non-B in the total number of cases of viral hepatitides in the republic.

[Experience with the use of a commercial immunoglobulin diagnostic agent for determining HBsAg in the reverse passive hemagglutination reaction under the conditions of Central Asia]. / Opyt primeneniia kommercheskogo immunoglobulinovogo diagnostikuma dlia opredeleniia HBsAg v reaktsii obratnoi passivnoi gemaggliutinatsii v usloviiakh Srednei Azii.

Use of twice-distilled water or addition of normal equine serum, preheated at 56 degrees C for 30 min and adsorbed with an adsorbent from the diagnostic kit, to normal saline (1 ml of serum per 100 ml of the saline) helps eliminate spontaneous agglutination of the tested diagnosticum during the detection of HBsAg with the use of reverse passive hemagglutination test, when the experiments are carried out in areas with high concentrations of salts and organic substances in the water.
