Voriconazole Therapeutic Drug Monitoring is a diagnostic test that measures the concentration of the antifungal medication voriconazole in your blood. This medication is used primarily to treat serious, invasive fungal infections. These can include infections caused by fungi such as Aspergillus and Candida, particularly in individuals with weak immune systems.
However, the levels of voriconazole in the body can be influenced by a number of factors, and there can be a fine balance between efficacy and toxicity. Too much can lead to adverse effects and toxicity, while too little might not effectively control the infection. As such, monitoring the blood levels of voriconazole can help tailor the most effective dose for each individual patient.
The test is done to monitor the concentration of voriconazole in the blood to ensure it is within the therapeutic range for effective treatment of fungal infections.
No, fasting is not required for this test.
A blood sample is used in this test.
Your healthcare provider will order this test when you begin taking voriconazole to establish the proper dosage, or if they suspect that the medication is causing side effects or not working effectively.
This test measures the concentration of voriconazole in the blood.

The ideal therapeutic range for voriconazole is typically between 1-5.5 µg/mL, but may vary based on your specific condition and response to the medication.
There are no specific precautions you need to take before this test.
Factors such as age, liver function, genetic differences, interactions with other medications, and timing of the last dose can affect voriconazole levels in the body.
If your test results are outside the therapeutic range, you should consult the healthcare provider who prescribed the medication.
No specific preparation is necessary for this test.
Factors such as dosage and timing of medication, diet, and interaction with other medications can affect voriconazole levels.
Non-modifiable factors include age, liver function, and genetic differences in how your body metabolizes the drug.
This test is a crucial part of treatment with voriconazole, ensuring that the medication is working effectively and safely. By monitoring voriconazole levels, healthcare providers can adjust dosage as necessary, providing personalized treatment for serious fungal infections.
