Do I have to be sober to determine the PSA value?
In contrast to many other blood value determinations, you do not need to be fasting to determine the PSA value. Whether or what you ate on the day of the blood sample collection does not influence the value. Also the time of day does not play a role in determining the PSA value.
What is the relationship between PSA levels and exercise?
The prostate reacts to pressure and mechanical irritation. Physical exertion can sometimes lead to an increased release of PSA and thus influence the PSA level in the blood. Therefore, greater physical exertion should be avoided before testing. Sport does not have to be avoided in general, but certain types of exercise such as cycling should be avoided one or two days before the test.
