title: [Detection of irregular anti-erythrocyte antibodies using the indirect antiglobulin test in a low-ionic-strength medium. Immunohematology Group of the French Blood Transfusion Society].
abstract: The detection of irregular antibodies is usually performed with serum by the indirect antiglobulin test (IAT) with a polyspecific antiglobulin reagent. In a first study in 1996, we compared the results obtained with 3,264 blood samples of patients drawn with or without anticoagulant: no significant difference was observed among the 240 allo-antibodies detected and identified. In this paper we report the comparison of the results obtained by IAT on column of filtration with two kinds of reagents: polyspecific and anti-IgG antibodies. Respectively 2,927 (76 contained an antibody), and 643 (161 contained an antibody) sera of patients were tested with methods ID-Diamed and Ortho-Biovue. Titrations of 153 other antibodies were also performed with the two reagents. Results showed no significant difference using either polyspecific reagent or the anti-IgG antibodies. This study proves that it is possible to perform screening of irregular antibodies on uncoagulated blood samples. This possibility allows automation as blood typing and screening of irregular antibodies can be carried out with the same sample.
