Abstract
It is indispensable to determine HBs antigen to prevent hepatitis which may be caused by blood transfusion in some cases.
However, since RPHA, RIA and ELISA methods have been performing in past years, they require a skillful technique with intricate handling, while in-hospital blood collection is being conducted in emergency requirements in order to transuse blood into patient without results to be obtained by clinical screening processes. In this clinical aspect, this paper (thesis) reports study with regard to the “LPIA-100” that enables to meet emergency screning for HBs antigen on the basis of (based on) the near infrared latex photometric immunoassay.
