Which tests are crucial for monitoring potential toxicity in patients receiving TB treatment?

Monitoring potential toxicity in patients undergoing treatment for tuberculosis is vital due to the side effects associated with anti-tuberculosis medications. The answer that encompasses both options A and B is particularly relevant because it highlights the required comprehensive approach to patient safety during treatment.

Serum creatinine and electrolytes are essential for evaluating kidney function and potential renal toxicity, especially as certain TB drugs can affect renal health. On the other hand, complete blood count and liver function tests are crucial for detecting hematologic effects, such as potential drug-induced liver injury, which is a known risk with many TB medications.

By choosing both A and B, it acknowledges that monitoring is not limited to just one aspect of patient health but rather embraces a multi-faceted strategy to encompass various organ systems, ensuring a more proactive approach in identifying and managing any adverse reactions that may arise during TB treatment.
