Screening tests can, unfortunately, yield inaccurate results at times. False negatives may miss a diabetes diagnosis, causing severe issues if untreated. On the other hand, false positives may be incorrectly flagged as having the condition when it's not present. Various elements like stress levels, health state, medications taken, and even lab inconsistencies could affect test accuracy. If there's any uncertainty about a result, getting extra testing done and speaking to medical professionals to analyze the situation thoroughly is essential.
