| pubmed-article:1509853 | pubmed:abstractText | The study has revealed the possibility of the contamination of serum with HBsAg under laboratory conditions during its treatment and preparation for analysis, which may be the cause of false positive results of HBsAg detection by the enzyme immunoassay (EIA). Excluding the factors of contamination, the authors demonstrate the efficacy of commercial systems, such as the passive hemagglutination test system "Gorky" and the EIA systems "Gorky" and "DIAplus", for the detection of HBsAg in the blood of donors in Moscow and Tashkent. | lld:pubmed |
