"Unexpected results" can be a powerful source of knowledge. If you're experimenting with
diet, and the PSA comes back right where you expected it, you have learned little.
Perhaps a little more confidence in the working hypothesis, but no new knowledge. If you
get an unexpected result, however, you may have an opportunity to learn something. Iron
spikes kills the diet, removal of soy kills the diet, removal of raspberries kills the diet. All
these came from an unexpected PSA result.
My last 5 PSA values are 0.525, 0.442, 0.435, 0.416 and 0.312. Boy, was the last value
unexpected. Could be a lot of information here if I can unravel it. Since I record dietary
changes I have made from one test period to another, I made a list of the possible
causes of this spike down in PSA. I plan to test the most likely first, then two at a time
until I get a hit. This can be more difficult than it sounds.
Perhaps the cause of the gap down was two or three changes in combination. Perhaps
it wasn't a change made in that test period, but rather in one or two test periods before,
that had a "ramp-up time" of months before the effect is visible. Perhaps it wasn't a
change I made at all, but rather a "seasonal", or "ripeness" or "source" issue of
something I have not otherwise changed. For example, the amount of "ellagic acid"
in red raspberries can vary from near zero to 150 mg per 100 gm of fruit. Ellagic acid
is associated with apoptosis (cell death) and is likely contributing to the positive results
of the diet.
Before I decipher the PSA "gap down" riddle, I have to make sure it's "real". First, I
will do a retest, looking for a lab error. Second, a repeatability test, making sure the
effect is actually there. But I do not want another large gap down, so I will do a "partial"
repeatability test, for a shorter period of time. This whole process could take three
months to a year.
