Abstract:
BACKGROUND: Blood loss due to laboratory phlebotomy among neonates is correlated with anemia as well as transfusion. In this study, microcolumn agglutination cards for performing ABO & RhD blood typing and direct antiglobulin tests in neonates were evaluated and compared with other established systems. Also, the blood group antibody production rates according to the age were calculated to determine the upper age limit for the new method. METHODS: Eighty subjects were tested by using the DianaGel Neonatal cards (Diagnostic Grifols, Barcelona, Spain), and the results were compared with those of the slide methods for ABO and RhD blood typing, and the DiaMed-ID DC-Screening I test (DiaMed, Morat, Switzerland) for direct antiglobulin tests. A total of 546 subjects who were under 12 months old were tested for the ABO back-typing, and 58 subjects with the AB blood type were excluded. RESULTS: The results of the DianaGel Neonatal card were in agreement with those of the conventional methods for all the subjects. Only one subject showed a discrepant result for the DAT between the DianaGel and DiaMed methods. Blood group antibodies were detected in 29 out of 169 (17.2%) one-day-old neonates, in eight out of 34 (23.5%) infants between one and three months of age and in 81 out of 96 (84.4%) infants between six and twelve months of age. CONCLUSION: The DianaGel Neonatal card showed at least equivalent performance as compared to that of the conventional methods, and it showed advantages for a low blood volume requirement and stronger agglutination grades. The DianaGel card is a suitable alternative for blood typing and DAT in infants under the age of 3 months and who do not necessarily need back-typing of the blood groups due to the low production rate of antibodies.
