A test for inflammation has a four-hour time limit, which can lead to inaccuracies. This is due to sample handling issues that arise during this timeframe. ALCOR Scientific has reported on the limitations of this test, specifically the four-hour ESR test stability limit.

The time limit can affect the accuracy of the test results, making it less reliable. ALCOR Scientific's report highlights the issues that can occur due to sample handling within this four-hour window.

Further details on the test and its limitations are available from ALCOR Scientific's report, which provides more information on the potential inaccuracies caused by the four-hour time limit and sample handling issues.
