Objective To assess the efficacy of microdetermination in the ATP bioluminescence assay (ATP CVA) of ovarian cancer chemosensitivity testing in vitro . Methods A micromethod ATP CVA was employed in determining the chemosensitivity of 35 specimens of fresh ovarian cancer cells using Victor 2 Multilabel Counter. Results ① By use of Victor2 Mutilabel Counter to determine ATP, in a range of 10 -9 10 -5 mol/ml, a linear relationship was remarkable between the log ATP and the log luminescence. The equation was Y= 0.892X+10 257, the correlation coefficient r was 0.998, P <0.01. ② The coefficient of variation obtained from ATP CVA was 7.3%. ③ The sensitivity of the test was 92.0%, the specificity 70.0%, and the total predictive accuracy of ATP CVA 87.1%. Conclusion With the use of Victor 2 Mutilabel Counter, ATP CVA is fast, eost effective, and easy to perform with only small error.
