수혈혈액에 있어서 HBs항원 검출빈도에 관한 연구
Study on the Frequency of HBs Antigen Positivity in Transfused Bloods
Chosun university hospital derives mostly its supply of bloods from other blood-donor centers, where all the donated bloods are tested for HBs antigen by means of CIEP method that is known to be less sensitive than RPHA method. Total 1518 bloods supplied from the other blood-donor centers were reexamined for HBs antigen by CIEP and RPHA method. The results are summerized as follows : 1) Out of the total 1518 tested bloods, HBs antigen-positive cases were 31 (2.0%)* by CIEP, 63(4.1%) by RPHA. * These 31 cases were totally HBs antigen-positive by RPHA. 2) Out of the 1487 cases showing HBs antigen negativity by CIEP, 32(2.2%) were HBs antigen-positive by RPHA. 3) Out of the 63 cases showing HBs antigen positivity by RPHA, 21(33.3%) were RPHA titer 5120 and over, and all of these were CIEP-positive. 13(20.6%) were RPHA titer 640 and below, and all of these were CIEP-negative. Out of 29 casts showing HBs antigen positivity at RPHA titer 1280 and 2560, 10 (34.5%) were CIEP-positive and 19(65.5%) were CIEP-negative.
