Blood Test for Ovarian Cancer Associated Antibodies (CAAb)

The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.
Verified May 2006 by Lab Discoveries Ltd..
Recruitment status was:  Recruiting

Lab Discoveries Ltd. Identifier:
First received: May 18, 2006
Last updated: March 1, 2007
Last verified: May 2006

Blood is collected from patients and cultured in a CimTube (a test tube with stimulation media) for several days. Following the culture step, the supernatant fluid is tested for the presence of CAAb on experimental test kits.

Null Hypothesis: There is no relationship between the presence or absence of ovarian cancer (OC) and the CAAb i.e. d=0.

Alternative Hypothesis: The expectation of the CAAb in the cancer population differs from that of the control population, i.e. m1 is not equal to m2. Since the sign of the difference is not important, the test will be two-sided.
