OPK
In a groundbreaking clinical study, over 10,000 men with high PSA scores were tested using Opko's 4KScore. The 4KScore trials were pivotal clinical trials. Biopsies were performed on all 10,000 men, and the results were compared to the patient's 4KScores. Here's what scientists discovered:
Men who had high 4KScores usually did have prostate cancer.
Only .6% of men who had low 4KScores had a dangerous form of prostate cancer. This represents an accuracy level of 99.4%, extremely good for any diagnostic tool.
