Abstract
In order to investigate the variability ofserum prostate-specific antigen(PSA) levels a total of 44 men 50 years or older with normal digital rectalexamination were enrolled. Blood samples were obtained three times withina day, and, immediately before and 72 hours after hospitalisation.Alterations in serum PSA value during the day and after hospitalisation,which might affect clinical decision, occurred in 15%of the cases withborderline PSA values. The results indicate that there may be significantchanges in serum PSA levels within a day and after hospitalisation.
