What's this test for?

This test is ideal if you're taking apixaban (Eliquis) for atrial fibrillation, DVT, or pulmonary embolism and need to check how much of the medication is in your blood. It helps if you have concerns about whether the drug is working as expected, especially if you've had unexpected bleeding or clotting symptoms while on treatment. It's also useful if you or your care team suspect missed doses or if kidney or liver issues might be affecting how your body processes the medication.

What happens after I get my results?

Your apixaban level will show up in your account along with the expected range so you can see exactly where your number falls. If your level looks unusually high or low, next steps might include reviewing your dosing schedule, checking for missed doses, or looking at other health factors like kidney function that can affect drug levels. A downloadable lab report is available in your account for your records. You can also use the trends feature to track your levels over time if you retest in the future.

Who should consider this test?

Anyone currently prescribed apixaban who wants to confirm the medication is at an effective level should consider this test. It's especially useful for people with kidney or liver conditions that can change how the body clears the drug, or for those who've noticed unusual bruising, bleeding, or clotting symptoms. People switching apixaban doses or restarting the medication after a pause may also want to check their levels.

What symptoms indicate I may need this test?

Watch for signs like unusual bruising, prolonged bleeding from small cuts, blood in your urine or stool, or unexpected swelling and pain that could signal a clot. Feeling like the medication isn't working, or experiencing side effects that seem too strong, are also good reasons to check your levels. If you've missed several doses or changed your routine significantly, testing can confirm where you stand.

When will I get my results?

Results are typically ready within about 7 days of your sample being processed at the lab. You'll get a notification once your report is available in your account. If your results suggest an urgent concern, such as signs of significant bleeding, seek medical care right away rather than waiting for the report.

What is apixaban and why does it matter?

Apixaban is a blood thinner that helps prevent dangerous clots from forming, which lowers the risk of stroke and other clot-related problems. It works by blocking a specific clotting factor in your blood called factor Xa. Because it affects how easily your blood clots, having the right amount in your system matters — too little may not protect you from clots, and too much can raise bleeding risk.

What does a high apixaban level mean?

A higher-than-expected level may mean the drug is building up in your system, which can raise your risk of bleeding. This can happen if your kidneys or liver aren't clearing the medication as quickly as usual, or if the dose is higher than your body needs. If you notice unusual bruising or bleeding along with a high result, seek medical care promptly.

What does a low apixaban level mean?

A lower-than-expected level might mean the medication isn't providing full protection against clots, which could happen if doses are being missed or taken inconsistently. It can also happen if something is causing your body to clear the drug faster than normal. Staying consistent with your dosing schedule and rechecking your levels can help clarify what's going on.

What causes high or low apixaban levels?

Missed or inconsistent doses are a common cause of lower levels, while taking doses too close together or having reduced kidney or liver function can push levels higher. Interactions with other medications can also change how apixaban is processed in your body. Body weight and overall health conditions can play a role as well.

How often should I retest?

Routine retesting isn't usually necessary for most people on apixaban, since it's designed to work at consistent doses without constant monitoring. However, retesting can be helpful if you've had a dose change, developed kidney or liver issues, or experienced symptoms that raise concern. Ask about a reasonable retesting schedule based on your specific situation and health changes.
