[Relationship between toxoplasma IgG and routine screening items of infectious diseases of blood donors].

Among 745 blood donors whose routine screening items were unqualified, the positive rate of Toxoplasma IgG (TOX-IgG) was 21.9%, which was higher than that of the blood donors whose routine screening items were qualified, and there was a significant difference (P < 0.01). The positive rates of TOX-IgG were 22.8% (99/435), 13.7% (16/117), 12.2% (15/123), 10.0% (5/50), 31.0% (9/29), and 34.2% (13/38) in the blood donors with abnormal ALT, positive HBsAg, positive anti-HCV, and positive anti-HIV, respectively, and all the positive rates of TOX-IgG mentioned above were higher than those in the donors whose routine screening items were qualified (P < 0.05 or P < 0.01). In conclusion, there are correlations between the positive rate of TOX-IgG and the qualified situation of routine screening items of infectious diseases in blood donors.
