Capillary Blood for Prostate-specific Antigen Testing: The PSA-CAP Study.

ABSTRACT: Risk-adapted prostate cancer (PC) screening is currently based on a combination of prostate-specific antigen (PSA) testing, risk assessment, and magnetic resonance imaging (MRI). Classical venous blood sampling is usually performed by health care professionals, which may reduce participation in future population-based screening programmes due to limited resources. The PSA-CAP study (NCT06626386) evaluated the feasibility of using capillary blood from fingertip sampling compared with venous blood for PSA determination, in order to facilitate access for PSA testing. This prospective study analysed 196 men aged 40-75 yr. PSA levels were measured from both capillary and venous blood using the same analytical method. The stability of samples stored at room temperature was assessed over a week.
