Why This Test Is Done
Your healthcare provider may order this test if you’re taking capreomycin to treat tuberculosis (TB). It helps monitor your response to the medication and check for potential side effects, such as kidney problems or drug resistance.
What to Expect Before the Test
No special preparation is needed. You may have a blood sample drawn from a vein in your arm, similar to other blood tests. If you’re on capreomycin, discuss this with your provider to ensure no timing conflicts with your medication schedule.
What the Results Mean
Results are typically reported as a concentration (e.g., micrograms per milliliter). While reference ranges vary by lab, abnormal levels may signal issues like inadequate drug absorption, toxicity, or resistance to the antibiotic.
Potential Side Effects & Risks
Capreomycin can cause side effects like hearing loss, kidney problems, or nerve damage. High levels in the blood may indicate these risks. Always report any unusual symptoms to your provider.
Reference range
Interpretive criteria: Susceptible (S), Intermediate (I), or Resistant (R) based on CLSI M24 or equivalent guidelines for slow-growing mycobacteria. Report includes MIC value and susceptibility interpretation at 20.0 ug/mL capreomycin concentration.N/A
No special patient preparation required. Specimen collection should occur prior to next dose of antimycobacterial therapy when possible to avoid transient suppression of organism growth.
