How should an Xpert test result be recorded if MTB is detected but rifampicin resistance is not?

When recording an Xpert test result where Mycobacterium tuberculosis (MTB) is detected but there is no indication of rifampicin resistance, it is important to follow the established protocols for documenting these findings clearly. In this case, the designation "T" (which stands for "Tuberculosis detected") is used to indicate the presence of the bacteria. Recording this result in red ink is a standard practice that helps ensure it stands out on the document, making it immediately recognizable as a significant positive result. This method of documentation is crucial for facilitating quick recognition and appropriate response from healthcare providers, as it highlights the need for further clinical management despite the absence of rifampicin resistance.

The other choices represent either incorrect designations or colors that do not adhere to the policy for indicating these results, which could lead to confusion or misinterpretation of the test findings. Clear and consistent documentation is essential in tuberculosis control programs to ensure proper treatment and management of patients.
