A BBC investigation has raised concerns over the accuracy and reliability of at-home prostate cancer tests, particularly rapid PSA (Prostate-Specific Antigen) tests.
These tests detect elevated PSA levels in blood samples, which could indicate prostate issues, including cancer. However, the BBC’s analysis of five different tests found significant inconsistencies: one test didn’t work, three were negative, and one produced a false positive – all from the same sample. PSA levels can be influenced by factors other than cancer, such as infections or recent physical activity.
Prostate Cancer UK has voiced concerns about the accuracy of these tests, emphasising the risk of false positives or false negatives. They argue that relying on such tests without a medical professional’s interpretation can be dangerous, leading either to unnecessary worry or false reassurance.
BIVDA were consulted by the BBC for the article, and were clear that members are providing high quality, accurate tests for use in line with their IFU’s. None of the tests referred to in the article were supplied by BIVDA members. Problems may arise when professional-use tests are being used incorrectly, as appeared to be the case for some of the tests they procured. As always, a diagnostic test is there to support clinical decision-making, rather than replace it.
