Background: Low ionic strength solution (LISS) is used to increase the rate of association of antibody to the corresponding antigen during antibody detection tests. A number of LISSs are available on the market. Aims: The efficiency of two commercial low ionic diluents, DiaMed ID-CellStab and Inverclyde LISS were assessed using the DiaMed-ID LISS Coombs microtube column system and an incubation time varying from 15 to 35 min. Materials and Methods: One-hundred samples containing five Rh antibodies (anti-D, anti-C, anti-E, anti-c and anti-e) were tested against commercial red cells using the two low ionic diluents after 15, 25 and 35 min. Results: The Inverclyde LISS detected 91, 95 and 96% of the Rh antibodies compared to 78, 79 and 83% for ID-CellStab after 15, 25 and 35 min incubation time, respectively, for both methods. Conclusions: The Inverclyde LISS is a more suitable and efficient diluent than ID-CellStab for the detection of Rh antibodies. The sensitivity of Rh antibody detection increased for the both methods as the incubation time increased.
