My previous bcr/abl was 0.005% on the International Scale, and my current one is 0.02% on the I.S. Can anyone tell me how to calculate the log increase? Thanks. Frank

Hi,

What disease do you have?  You might want to check in with that particular forum.  Click the "Living with..." link and there is a list of illnesses and each is a link to a forum.

1 log (the way it is used to describe response) is one decimal place. The first result was 0.005 so for a 1 log increase you would need to increase to 0.05 i.e. the increase you have had is less than one log and based on the accuracy of the tests not statistically significant. Still loosing a 0 is never nice.

0.6 log.  Divide one by the other and take the log of the answer.  LOG10(A/B) in excel.

PCR tests are notoriously unreliable at those kind of levels and so it is within the limits of error.
