The phi score is a better predictor of prostate cancer than the total psa test alone or the free psa test alone. These 3 tests are mathematically combined in a formula that results in a prostate health index or phi score. Table 1 represents clinical study data analyzed to estimate an individual patient s probability of having detectable prostate cancer based on beckman coulter phi results when that patient has a psa in the diagnostic gray zone between 4 and 10 ng ml.
Hopefully no news is not assumed to be a normal test. In conditions of increased glandular size and tissue damage psa is released into circulation. It is common to wait a day or two for most results to come back.
