What is the primary purpose of documenting TST results?

• A. To schedule follow-up vaccines
• B. To track drug prescriptions
• C. To record patient vitals only
• D. To identify possible TB exposure and need for follow-up evaluation

Answer: (D)

Documenting TB skin test results is about identifying who may have been exposed to TB and whether they need further evaluation. A TST shows if there has been infection, but it doesn’t diagnose active TB on its own, so a positive or high-risk result prompts follow-up steps such as reviewing symptoms, ordering a chest radiograph, and considering contact tracing or additional testing. Recording the result ensures clinicians and public health teams can track exposure history and guide the next actions to prevent progression or spread. Other options miss the mark because vaccines, drug prescriptions, or merely recording vitals aren’t the primary purpose of documenting TB test results.
