Abstract: Objective To evaluation the performance of a heart-type fatty acid-binding protein (H-FABP) ELISA detection kit in
the clinical diagnosis of acute coronary syndrome (ACS). Methods Plasma or serum samples from 160 suspected ACS patients
hospitalized in General Hospital of PLA were examined using Lanzhou H-FABP reagent kit and Holland H-FABP kit.
Correlation of the two kits was evaluated and Kappa test was used to examine the consistency of the results of the two
products. Results The sensitivity of H-FABP diagnosis of ACS detection Lanzhou kit was 91.8%, the specificity was 88.7%, and
the total diagnostic rate was 90.42% . The sensitivity of H-FABP diagnosis of ACS detection Holland kit was 90.3% , the
specificity was 86.8%, and the total diagnostic rate was 88.75%. The test results showed that two products yielded comparable
results (P=0.668, >0.05) with a good consistency (Kappa=0.726, P<0.01). Conclusions H-FABP ELISA detection kit produccted
by LanZhou biological research institute has a good correlation with H-FABP detection kit produced by HBT company of
Holland and has the potential for clinical application.
