What's this test for?

This test is ideal if you're experiencing unexplained blood clots, a history of vascular problems, or if you have diabetes and want to understand your clotting risk. It's also useful if you have a family history of clotting disorders and want to check whether your blood is clotting more or less than it should. The test looks at how active your clotting system is right now.

What happens after I get my results?

Your results will show up in your account along with the normal range for the Thrombin-Antithrombin Complex so you can see exactly where you fall. If your level is outside the normal range, simple next steps include reviewing lifestyle factors like activity level and hydration, and considering a retest in a few months to track changes. If your result is significantly elevated or you have symptoms like sudden swelling, pain, or shortness of breath, seek medical care right away. You can download the full lab report anytime and use the trends feature to watch how your levels change over time.

What symptoms indicate I may need this test?

Signs that may point to a clotting imbalance include unexplained leg swelling or pain, unusual bruising, recurrent blood clots, or a history of miscarriages. People with diabetes who notice circulation problems, numbness, or slow-healing wounds may also want to check their clotting activity. If you've had a family member with a clotting disorder, that's another reason to consider this test.

How can I naturally support healthy blood clotting balance?

Staying active, keeping hydrated, and avoiding long periods of sitting can help support normal blood flow and clotting balance. Eating a diet rich in omega-3 fatty acids, such as fish and flaxseed, may help support healthy circulation. Avoiding smoking and managing blood sugar levels, especially if you have diabetes, also plays a big role in keeping your clotting system balanced.

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 as soon as your report is available in your account. There's no need to call or wait on hold — everything is accessible online as soon as it's ready.

Who should consider this test?

People with diabetes who want to understand their vascular risk, those with a personal or family history of blood clots, and anyone recovering from a clotting event may benefit from this test. It's also useful for people being monitored for hypercoagulable conditions. If clotting problems run in your family, this test can give you helpful information.

What is the Thrombin-Antithrombin Complex and why does it matter?

The Thrombin-Antithrombin Complex forms when your body activates its clotting process, and antithrombin works to keep that process in check. Measuring it tells you how balanced your clotting system is — too much activity can raise your risk of dangerous clots, while a deficiency can signal your body isn't controlling clotting properly. This makes it a useful marker for understanding vascular health, especially in people with diabetes.

What does a high Thrombin-Antithrombin Complex result mean?

A high result means your blood is forming more clotting complexes than normal, which can point toward a hypercoagulable state or ongoing vascular stress, often linked with diabetes complications. This doesn't automatically mean something is wrong, but it's worth paying attention to, especially if you have other risk factors. Simple steps like staying active, managing blood sugar, and avoiding smoking can help, and a retest can confirm whether the level stays elevated.

What causes high or low Thrombin-Antithrombin Complex levels?

High levels are often linked to conditions that increase clotting activity, such as diabetes-related vascular damage, inflammation, or recent clotting events. Low or deficient levels may be tied to antithrombin deficiencies, which can make it harder for your body to naturally regulate clotting. Lifestyle factors like prolonged immobility, smoking, and poorly managed blood sugar can also influence these levels.

How often should I retest my Thrombin-Antithrombin Complex levels?

If your first result is outside the normal range, retesting every 3 to 6 months can help you track whether lifestyle changes are making a difference. If you have diabetes or an ongoing vascular concern, more frequent monitoring may be helpful. The trends feature in your account makes it easy to see these changes over time.
