Abstract:
Objective To compare test results of antinuclear antibodies (ANA ) using different brands kit and methodology . Methods 180 cases who accepted serum ANA detection in hospital from April to December 2012 were choosen ,in which 145 cases of positive serum and 35 cases of healthy control .The 180 cases were tested for ANAs by YHLO ANA-17S ,EUROIMMUN ANA profile 3 and ANA IIFA kits at the same time ,and all parameters about ANA decetion were compared such as sensitivity ,specifici-ty ,positive predictive value ,negative predictive value and the coincidence rate between the two kinds of kits .Results The sensitivi-ty of YHLO ANA-17S ,EUROIMMUN ANA profile 3 and EUROIMMUN ANA IIFA was 94 .8% ,90 .4% ,95 .6% ;specificity was 88 .9% ,91 .1% ,93 .3% ;positive predictive value was 96 .2% ,96 .8% ,97 .7% ;negative predictive value was 85 .1% ,75 .9% , 87 .5% ;the coincidence rate between the EUROIMMUN ANA profile 3 and EUROIMMUN ANA IIFA was 84 .0% (P>0 .05) ,be-tween the YHLO ANA-17S and EUROIMMUN ANA IIFA was 80 .0% (P>0 .05) ,between theYHLO ANA-17S and EUROIM-MUN ANA profile 3 was 93 .0% (P> 0 .05) .Conclusion Three kits for detecting ANAs have good sensitivity and specificity , which can be used for autoimmune disease detection .Laboratory tests result should be combined with clinical symptoms according to the diagnostic criteria to make the final diagnosis .
