What labs are in a thrombophilia panel?
Ten (10) genes associated with hereditary thrombophilia are sequenced and analyzed: protein S (PROS1), protein C (PROC), antithrombin III (SERPINC1), factor VIII (F8), factor V (F5), factor II (F2), MTHFR, fibrinogen (FGA), plasminogen (PLG) and plasminogen activator inhibitor, type I (formerly called PAI1, now …
What is thrombophilia workup?
A workup for thrombophilia is usually indicated only in patients with one or more of the following risk factors: Recurrent thromboembolic episodes. Thromboembolism at a young age (ie, < 40 y) A family history for thromboembolism. Thrombosis in an unusual site.
What is a thrombosis panel?
The Thrombosis Panel includes testing for Prothrombin (Factor II) G20210A mutation analysis and Factor V Leiden mutation analysis with reflex to Factor V HR2 if the Factor V Leiden testing is positive.
What is thrombophilia profile test?
Thrombophilia Profile – Maxi test helps diagnose abnormalities of Blood coagulation.
What is coagulation profile test?
What is a coagulation profile? A coagulation profile (coags) includes INR, APTT, platelets and fibrinogen. It is a screening test for abnormal blood clotting because it examines the factors most often associated with a bleeding problem. It does not cover all causes of bleeding tendencies.
When should a thrombophilia screen be done?
It is recommended that thrombophilia screening should be undertaken in the following patients:
- Unprovoked venous thromboembolism before the age of 40 years.
- Recurrent unprovoked thromboembolism.
- Thrombosis in unusual sites.
- Unprovoked venous thromboembolism in a patient whose first degree relative meets criteria 1-3.
What is included in a coagulation panel?
How is thrombophilia test done?
Thrombophilia is diagnosed by blood tests. Tests are done some weeks or months after having a DVT or pulmonary embolism, as the presence of these conditions can affect the results. Usually you have to wait until you have been off blood-thinning medication (anticoagulants), such as warfarin, for 4-6 weeks.
What is PTT and INR?
The prothrombin time (PT) test measures how quickly blood clots. The partial thromboplastin time (PTT) is mainly used to monitor a person’s response to anticoagulant therapies. The international normalized ratio (INR) calculation helps ensure that PT test results are standardized and accurate.
What does PT and aPTT test for?
The partial thromboplastin time (PTT; also known as activated partial thromboplastin time (aPTT)) is a screening test that helps evaluate a person’s ability to appropriately form blood clots. It measures the number of seconds it takes for a clot to form in a sample of blood after substances (reagents) are added.
Why thrombophilia test is done?
You should get a test for thrombophilia if: You have a strong family history of blood clots. You have clots without a known cause (no risk factors). You have clots in unusual locations.
What is the difference between PT INR and PTT?
The prothrombin time (PT) test measures the rate of blood clotting in seconds and the international normalized ratio (INR) test ensures that PT results are standardized. The partial thromboplastin time (PTT) is mainly used to monitor a person’s response to blood thinners.
What is difference between aPTT and PTT?
Partial thromboplastin time (PTT) and activated partial thromboplastin time (aPTT) are used to test for the same functions; however, in aPTT, an activator is added that speeds up the clotting time and results in a narrower reference range.
What are the signs of thrombophilia?
Symptoms of thrombophilia
- throbbing or cramping pain in 1 leg (rarely both legs), usually in the calf or thigh.
- swelling in 1 leg (rarely both legs)
- warm skin around the painful area.
- red or darkened skin around the painful area.
- swollen veins that are hard or sore when you touch them.
What is INR and aPTT?
The PT/INR is used to assess the extrinsic or tissue factor pathway, while the aPTT is used to assess the function of the intrinsic or contact pathway of coagulation (4). Deficiencies in the common pathway are associated with prolongations of both the PT/INR and aPTT (4).
Is the Arup test FDA approved?
This test was developed and its performance characteristics determined by ARUP Laboratories. It has not been cleared or approved by the US Food and Drug Administration. This test was performed in a CLIA certified laboratory and is intended for clinical purposes. Counseling and informed consent are recommended for genetic testing.

Who should be tested for thrombophilia?
Children – very low risk for thrombophilia and should only have testing performed in consultation with hematologist (ACMG)
How is the prothrombin (F2) variant (G20210A) diagnosed?
For prothrombin variant testing (inherited thrombotic risk factor), order prothrombin (F2) c.*97G>A (G20210A) pathogenic variant Results of F5 genotyping can be accurately determined for individuals on oral anticoagulant and standard heparin therapy
