Why This Test Is Done
Your healthcare provider may order this test if you’re taking capreomycin to check if the drug is working properly or if your body is handling it well. It’s particularly useful for patients with tuberculosis who may be resistant to other treatments.
What to Expect Before the Test
No special preparation is needed. You may have a small needle inserted into your arm or vein to draw blood. If you’re on capreomycin, your provider may ask you to stop taking it temporarily before testing to avoid interference.
What the Results Mean
Results are used to adjust your medication dose if needed. Low levels might indicate the drug isn’t being absorbed well, while high levels could signal problems like kidney issues or improper dosing.
Common Causes of Abnormal Results
Factors like kidney disease, improper dosing, or interactions with other medications can affect capreomycin levels. Your provider will review your full medical history and other test results to interpret the results accurately.
Reference range
