How It Works What is the blood test based on? The ONCOblot® blood test identifies a specific type of protein in the blood, ENOX2, which exists only on the surface of a malignant cancer cell. The ENOX2 proteins are shed into the circulation and can be detected in the blood. These proteins serve as highly sensitive markers for confirmation of cancer presence.

Normal or Therapeutic? Let’s look at the three tests used to determine bleeding or clotting times: 1  Prothrombin Time (PT) — this blood test measures how long it takes blood to clot and can be used to check for bleeding problems. 2  International Normalized Ratio (INR) – is a standardized way to report results of bleeding time.

- Various platelet function tests are used to evaluate the ability of platelets to clump together and begin to form a clot. They may be used for a variety of reasons. To identify and help diagnose platelet dysfunction in those with a history of excessive bleeding.

- This testing is used to evaluate fibrinogen, a protein that is essential for blood clot formation. When there is an injury and bleeding occurs, the body forms a blood clot through a series of steps.

Lupus Anticoagulant Testing Lupus anticoagulant testing is a series of tests used to detect lupus anticoagulant (LA) in the blood. LA is an autoantibody associated with excess blood clot formation. LA testing may be used to help determine the cause of: 1  An unexplained blood clot (thrombosis) in a vein or artery. 2  Recurrent miscarriages. series of tests is used to confirm or rule out the autoantibody: 1  It is recommended that two tests be used to detect lupus anticoagulant. 2  The most sensitive tests are dilute Russell viper venom test (DRVVT) and a LA-sensitive PTT (PTT-LA), one that uses low levels of phospholipid reagents.

Fibrinogen measurement This test measures the amount of fibrinogen (a protein necessary for blood clot formation) in blood. It is used to detect certain clotting disorders[1][2][3]. What are other names for this test?

Blood Clots You may be sent for one or more of the following tests: 1  Venous ultrasound: This test is usually the first step for confirming a venous blood clot. Sound waves are used to create a view of your veins. 2  Chest CT scan: If your doctor suspects you have a pulmonary embolism, you may undergo a CT scan.

- Blood Laboratory. Two laboratory tests are used commonly to evaluate coagulation disorders: Prothrombin Time (PT) which measures the integrity of the extrinsic system as well as factors common to both systems and Partial Thromboplastin Time (PTT), which measures the integrity of the intrinsic system and the common components.

D-dimer Test D-dimer tests are used to help rule out the presence of an inappropriate blood clot (thrombus). Some of the conditions that the D-dimer test is used to help rule out include: Deep vein thrombosis (DVT) Pulmonary embolism (PE) Stroke.

D-Dimer Fragment D-dimer, fibrin degradation fragment. This is a blood test to look for a substance called D-dimer. This test is used to rule out a blood clot. D-dimer is a protein fragment from the break down of a blood clot. Blood clots generally begin to slowly break down after they are formed, and this process releases D-dimer into the blood.

Overview Prothrombin time test results can be presented in two ways. The average time range for blood to clot is about 10 to 14 seconds. A number higher than that range means it takes blood longer than usual to clot. A number lower than that range means blood clots more quickly than normal.

Blood Tests That Help Explain Stroke 1 High cholesterol is a major risk factor for stroke and may indicate that you are at greater risk of having a stroke.  Coagulation tests, including prothrombin time (PT), partial thromboplastin time (PTT), and international normalized ratio (INR), check the speed at which your blood clots.

- A positive test means that you may be making blood clots. The test does not tell where the clots are or why you are making clots. Your provider may order other tests to see where clots are located. A positive test may be caused by other factors, and you may not have any clots.

D-Dimer Test  [en EspaÃ±ol] D-Dimer Test. Guide. A d-dimer test is a blood test that measures a substance that is released when a blood clot breaks up. Doctors order the d-dimer test, along with other lab tests and imaging scans, to help check for blood-clotting problems. A d-dimer test can also be used to check how well a treatment is working.

Prothrombin Time (PT) w/INR Blood Test A PT/INR Blood Test is often used to monitor patients taking warfarin, a blood-thinning medication, to ensure the dosage is providing an appropriate balance between preventing clotting and causing excessive bleeding. Periodic tests may be ordered to assess the efficacy of the prescription.
