title: [Application of a micromethod in ovarian cancer chemosensitivity testing in vitro].
abstract: 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 Victor 2 Multilabel 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%.
  
  
  CONCLUSIONS
  With the use of Victor 2 Multilabel Counter, ATP-CVA is fast, cost-effective, and easy to perform with only small error.
