Why This Test Is Done

Your healthcare provider may order this test if you’re receiving streptomycin therapy to prevent infections. It helps ensure the antibiotic is working properly and at the right dose without causing harmful side effects.

What to Expect Before the Test

No special preparation is needed. You’ll likely have a small needle inserted into a vein (usually in your arm) to draw blood. If you’re on long-term treatment, your provider may schedule regular tests to track your levels.

What the Results Mean

Results are used to adjust your medication if needed. Low levels may mean the antibiotic isn’t working well, while very high levels could indicate toxicity. Your provider will discuss these findings with you.

Possible Side Effects

Streptomycin can cause side effects like nausea, dizziness, or kidney issues if levels are too high. Your provider will monitor you closely during treatment.
