Introduction: A comparative study of blood cross match between gel card technique and conventional tube method wasundertaken on approx 1000 sample conducted in Sanjay Gandhi Memorial Hospital ,Rewa associated with Shyam shahmedical college Rewa .Material & Methods: most commonly conventional tube method are used widly. Now new technique of cross matching isintroduced . In this study Matrix gel card[16] method based on indirect coombs test for cross match and conventional tubemethod including saline tube method and indirect coombs tube method used.Observation and result: one thousand sample is taken for the study and out of this 996 sample is compatible using indirectcoombs gel card and indirect coombs tube test and 04 sample shows incompatibility of both test ,whereas in saline methodwithout using coombs reagent shows 100% compatibility, if we use coombs indirect test, 04 sample shows false positiveand 04 sample shows false negative of previously 100% compatible result. Sensitivity and specificity is 100% of gel cardand indirect coombs tube test using AHG, whereas saline tube test specificity is 99.6% .And positive predictive value 100%for Gel card and indirect coombs test[5][6] using AHG and 99.6%for saline tube method if AHG not used.Conclusion : Gel card used in blood cross match is easy to performed and recorded test and more sensitive and specific thenconvention saline method whereas indirect coombs tube test is sensitive and specific as Gel card but cannot record and moretime consuming than saline and gel card method.
