IMPORTANT NEW FINDING FROM JOHNS HOPKINS?
I received a bulletin though my Google Alerts last month indicating that Johns Hopkins reported a significant new finding that, “should save men with early prostate cancer from making any irrevocable decisions too hastily.”
And, that new finding? Having sex within 72 hours of your PSA test can produce a false reading.
Hello… Isn’t this old news? We’ve been talking about this for five years, along with the fact that there are some conditions that can cause false readings for up to 6 weeks. It’s in my book, in two places.
This information was published in the August 1998 Journal of Laboratory Medicine. Here are some other things that can cause false readings, from page 190 in my book.
| Condition/Manipulation | Effect on PSA Increase | Persists |
| Acute bacterial prostatitis | 5-7 fold | 6 weeks |
| Acute urinary retention | 5-7 fold | 6 weeks |
| Exercise - bicycle | 0-3 fold | 1 week |
| Prostate Biopsy | Very variable | 6 weeks |
| Prostate massage | Variable | 6 weeks |
| Ejaculation | Variable | 3 days |
| TURP | Very Variable | 6 weeks |
