Blood Clotting Tests

Activated Protein C

One of the clearest measures of your body's built in defense against dangerous blood clots.

Antithrombin III Activity

Uncover a hidden clotting vulnerability that standard blood tests never check.

D-Dimer

Rule out a dangerous blood clot in your legs or lungs when you have symptoms that could point to one.

Factor II Activity

A direct read on one of your most important clotting proteins, when standard clotting tests leave questions unanswered.

Factor IX Activity

See whether an overactive clotting protein is quietly raising your clot risk, which a standard coagulation panel misses.

Factor V Activity

Separate a true Factor V activity problem from the Factor V Leiden clot-risk test.

Factor VII Activity

See whether one low clotting protein is behind an unexplained long prothrombin time, and how much it raises your bleeding risk before surgery or childbirth.

Factor VIII Activity

Factor X Activity

Check the shared clotting protein that can explain bruising or bleeding when broad clotting screens don't name the cause.

Factor XI Activity

Find a clotting-factor problem routine clotting tests can miss after unexplained clots, young stroke, or surgery-related bleeding.

Factor XII Activity

An unexplained long clotting time can point to factor XII, a protein that usually changes the lab report more than your bleeding risk.

Factor XIII, Functional

Check clot strength when bleeding, deep bruises, wound problems, or pregnancy loss don't fit a normal PT and aPTT.

Fibrinogen Activity

The clearest read on whether your clotting machinery is actually working, beyond what a routine clotting panel can tell you.

Fibrinogen Antigen

See whether silent inflammation and clotting risk are building up beyond what standard blood tests reveal.

INR

Your clearest read on whether your blood is clotting too fast or too slow, before a stroke or bleed forces the answer.

Lupus Anticoagulant

Uncover a hidden clotting risk that standard blood work never checks and routine cholesterol panels completely miss.

PAI-1

See whether your clot-dissolving system is slowing down, tying your metabolic health to your risk of a future heart attack.

PTT-LA Screen

Catch the hidden antibody behind unexplained clots, miscarriages, or odd clotting results, often missed by a standard coagulation panel.

Platelet Count

Bleeding risk, iron loss, inflammation, marrow disease, and sometimes hidden cancer can all leave clues in your platelet count.

Protein C Activity

Reveal whether your body's built-in clot prevention system has a hidden weak spot that standard blood tests never check.

Protein S Activity

Reveal a hidden weakness in your body's clot-prevention system that standard blood tests never check.

Prothrombin Time

The most direct measure of your liver's protein-making power, invisible on a standard liver enzyme panel.

aPTT

Catch a clotting imbalance before a blood clot, unexplained bruising, or surgery forces the question.

dRVVT Screen

A widely used first-line signal of a hidden clotting antibody that drives unexplained blood clots and miscarriages.
