[Screening analysis of irregular antibodies from random donor population in Shaoguan area].

The study was purposed to analyze the frequency and distribution of irregular antibodies in Shaoguan area. Screening 15 033 random donor antibodies in Shaoguan area by screening cells, polybrene and antiglobulin tests. The results indicated that the irregular antibodies were found in 42 samples.

[Correlation of newborn hemolytic disease with ABO antibodies in sera of pregnant women].

To investigate the relations between morbidity of hemolytic diseases of newborn and ABO antibodies (HDN) in sera of Han and Yao nationality, pregnant women were examined before and after delivery. Antibodies screen, direct antiglobulin test, free antibodies and elution test were all performed. The results indicated that immunologic ABO antibodies of Han people were found in 673 cases out of 1,471 Han pregnant women, and was also found in 28 cases out of 65 Yao pregnant women, and there was no significant difference of incidences between Han and Yao nationality.

[Study on blood ABO typing in patients with autoimmune hemolytic anemia].

To explore effect of autoantibody on identification of ABO and RhD blood group, the blood samples of 38 patients with autoimmune hemolytic anemia (AIHA) were identified by routine typing and typing after chloroquine elution test as well as PCR. The results showed that out of 38 patients with AIHA, 11 cases (31.6%) of ABO blood group were difficulty typed, indirect antiglobulin test were positive, and contradiction between cells typing and sera typing were observed.
