What's this test for?

This test is ideal if you're currently taking posaconazole to prevent or treat a serious fungal infection and need to confirm the drug is at a working level in your body. It's especially useful if you have a weakened immune system, such as from chemotherapy or an organ transplant, where fungal infections are a serious risk. This test helps if you have concerns about whether your medication dose is too low to work or too high to be safe.

How should I prepare for this test?

How can I naturally support proper absorption of my antifungal medication? While posaconazole itself must be taken exactly as directed, you can support absorption by taking it with a full meal or acidic beverage, since the drug needs stomach acid and fat to be absorbed well. Staying well hydrated and avoiding acid-reducing products like antacids or acid blockers around dosing times can also help keep levels steady. Consistent timing of your doses each day helps avoid the ups and downs that can throw off your levels.

What happens after I get my results?

Your posaconazole level will appear in your account along with the therapeutic range so you can see exactly where your result falls. If your level is below the target range, next steps often include reviewing how you're taking the medication, since food and stomach acid affect absorption; if it's dangerously high or you feel unwell, seek medical care right away. You can download the full lab report from your account at any time, and the trends feature lets you track your levels over multiple tests to see if your therapy is staying consistent.

When will I get my results?

Results for this test are typically ready within about 7 days of your sample being processed at the lab. This turnaround allows for the specialized testing needed to measure precise drug levels in your blood. You'll receive a notification as soon as your results are posted to your account, so there's no need to check repeatedly.

Who should consider this test?

Anyone currently prescribed posaconazole for prevention or treatment of a fungal infection should consider this test, especially people with weakened immune systems from cancer treatment, organ transplants, or blood disorders. It's also useful for anyone whose infection symptoms aren't improving despite being on the medication, since low drug levels could be the reason. People switching from another antifungal like itraconazole or fluconazole may also want to confirm their new levels are adequate.

What symptoms indicate I may need this test?

If you're on posaconazole and still experiencing fever, mouth sores, difficulty swallowing, or other signs of an ongoing fungal infection, it may mean your drug levels are too low to be effective. On the other hand, new side effects like nausea, liver discomfort, or unusual fatigue could suggest levels are too high. Testing helps clarify whether your symptoms are related to the medication dose rather than guessing.

What is posaconazole and why does it matter?

Posaconazole is an antifungal medication used to prevent or treat serious fungal infections, particularly in people whose immune systems are too weak to fight them off on their own. Because everyone absorbs and processes this drug differently, the same dose can lead to very different blood levels from person to person. Checking your actual level matters because too little won't stop the infection, while too much can cause unwanted side effects.

What does high posaconazole mean?

A high posaconazole level means more of the drug is in your bloodstream than needed for effective treatment, which can raise the chance of side effects like stomach upset, liver strain, or headaches. This can happen if the dose is too high for your body or if it's building up over time. If your result comes back high, review your dosing schedule and reach out for medical care if you notice new symptoms.

What does low posaconazole mean?

A low posaconazole level means the drug hasn't reached the amount needed to fight off a fungal infection effectively, which raises the risk that treatment won't work. This is often caused by poor absorption, taking the medication on an empty stomach, or skipping doses. Taking the medication consistently with food and at the same time each day can help bring levels up.

How often should I retest?

Retesting is commonly done periodically throughout treatment to make sure your posaconazole level stays steady and effective, especially after any dose changes. If your infection risk is high or your levels have been unstable, more frequent testing helps catch problems early. Using the trends feature in your account makes it easy to spot patterns over time and decide when another test makes sense.
