A major study suggests that hundreds of thousands of people could have an underlying blood condition that is not detected by routine tests, potentially increasing the risk of serious outcomes. The reporting says the condition may remain “hidden” because standard measurements can appear normal.
According to the articles, the increased risk linked to the condition includes cancer, heart disease, and early death. The sources do not indicate that current testing is definitively missing all cases, but they describe a problem of detection when results fall within ranges considered acceptable by conventional screening.
Both outlets frame the findings as raising concern for large segments of the population in the UK and emphasize the health implications. However, they do not provide detailed methodological information or identify the specific blood condition in the supplied text, so the full clinical context and the exact scope of “hidden” cases are not specified in these summaries.
