What's this test for?

This test is ideal if you're experiencing unexplained blood clots, excessive bleeding, or bruising that won't go away. It's also useful if you have a personal or family history of clotting disorders and want to understand how your body breaks down clots. Your results can help explain symptoms tied to abnormal blood clotting or dissolving processes.

What's included in this test?

This test measures Tissue Plasminogen Activator, a protein your body uses to break down blood clots. Checking this single marker helps show whether your body's clot-dissolving system is working too slowly, too quickly, or normally, which matters for understanding clotting risk or unexplained bleeding.

What happens after I get my results?

Your results will show up in your account with a clear explanation of the normal range for this marker, so you know exactly where you stand. Depending on your value, next steps might include lifestyle changes like improving circulation through movement, or retesting after a set period to track changes. If your result falls far outside the normal range, seek medical care promptly. You'll also be able to download a standard lab report and track this result over time using the trends feature.

How can I naturally support healthy blood clotting balance?

Staying active with regular movement helps keep your blood flowing well and supports normal clotting function. Drinking enough water, eating a balanced diet with less processed food, and avoiding smoking can also help your circulatory system work properly. If you sit for long periods, taking breaks to walk around can reduce clot-related risks.

When will I get my results?

Results are typically ready within about 7 days of your sample being collected. Once processed, they'll automatically appear in your online account where you can view and download them. You'll get a notification so you know exactly when to check.

Who should consider this test?

This test is a good fit for people who've had unexplained blood clots, unusual bruising, or bleeding episodes. It's also worth considering if you have a family history of clotting or bleeding disorders, or if you're being evaluated for a condition affecting your fibrinolytic system. People recovering from clot-related events who want to monitor their status may also benefit.

What symptoms indicate I may need this test?

Watch for symptoms like sudden swelling or pain in a limb, unexplained bruising, prolonged bleeding from small cuts, or a history of blood clots without a clear cause. Shortness of breath or chest pain can sometimes be linked to clotting issues as well. If any of these symptoms are severe or sudden, seek medical care right away.

What is Tissue Plasminogen Activator and why does it matter?

Tissue Plasminogen Activator, or TPA, is a protein your body makes to help break down blood clots once they've formed. It matters because if your levels are too low, clots may not dissolve properly, raising the risk of complications. If levels are too high, your blood may not clot enough when it needs to, leading to excess bleeding.

What does a high or low TPA result mean?

A high result may mean your body is breaking down clots too quickly, which can sometimes lead to excess bleeding or bruising. A low result may suggest your body isn't dissolving clots efficiently, which could raise the risk of clots forming or lingering. Either way, the direction of the result helps explain symptoms you may be having.

How often should I retest?

If your first result is within the normal range and you have no ongoing symptoms, you likely don't need frequent retesting. If you're managing a known clotting or bleeding concern, retesting every few months can help you track whether your levels are moving in the right direction. Always retest sooner if new symptoms appear.
