serologically positive

Results: Of 2 800 patients 72 positive cases were found more than one times serologically. HGV-Ab was detected in 72 persons ( 2.6% 72/ 2 800).

结果：经两次以上血清学证实抗-HGV-Ab阳性者共72例，占被检查者26%（72/2800）。

Positive definition method was used for the ABO blood typing while Rh blood type was determined serologically through saline medium method. At the same time, the Rh phenotypes were investigated in RhD-negative individuals.

对ABO血型采用正定玻片法、Rh血型采用血清学盐水介质法测定，另外对RhD阴性个体检测Rh血型血清学表型。
