If an analyst disrupts a control point, what should they do next?

When an analyst disrupts a control point, the appropriate next step is to reanalyze the sample. This is crucial for maintaining the integrity and reliability of the data obtained from the analysis. A control point typically represents a standard or expected result that should be within a specific range. Disrupting this control point indicates that there may have been an error or unexpected variance in the testing conditions or sample handling.

By reanalyzing the sample, the analyst can confirm whether the initial results were accurate or if the disruption had a significant impact on the outcome. This process helps to ensure that any decisions based on the data reflect true conditions in the wastewater being analyzed. Reanalyzing allows the analyst to correct errors and report reliable results, which is essential in all aspects of laboratory work, especially in wastewater analysis where compliance with regulations is vital.

The other choices do not adequately address the need for accuracy and quality control. Ignoring the error would compromise the integrity of the results, simply documenting the mistake without corrective action does not rectify potential impacts, and changing the control point would disregard the parameters that are set to ensure consistent and accurate measurements.
