结局指标
主要结局
Presence of heterophilic antibodies in the serum of participants
时间窗: 1.5 years
Heterophilic antibodies will be measured in the Blood serum of participants by sandwich Elisa assay
Altered PSA levels due to the Presence of Heterophilic antibodies
时间窗: 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
