Altered PSA Test Due to Possible Suspected Heterophilic Antibodies

May 29, 2017 updated by: University of Zurich
The purpose of this study is to investigate if clinically non explainable high or low Prostate-specific antigen (PSA) levels are associated with heterophilic antibodies in the serum of participants. The investigators will examine if heterophilic antibodies are the reasons of altered PSA levels.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Presence of heterophilic antibodies in the serum of participants
Time Frame: 1.5 years
Heterophilic antibodies will be measured in the Blood serum of participants by sandwich Elisa assay
1.5 years
Altered PSA levels due to the Presence of Heterophilic antibodies
Time Frame: 1.5 years
If heterophilic antibodies were present in the serum of the participant, another PSA test will be ran after absorbance of heterophilic antibodies to investigate whether PSA levels are changed without the presence of heterophilic antibodies
