What is a normal coagulation result?

The normal range for clotting is: 11 to 13.5 seconds. INR of 0.8 to 1.1.

What are COAG labs?

Clinicians frequently order coagulation tests, such as the prothrombin time (PT), activated partial thromboplastin time (aPTT), and thrombin time (TT), to assess blood clotting function in patients.

What is PT and PTT for?

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.

What is normal range of platelets?

A normal platelet count ranges from 150,000 to 450,000 platelets per microliter of blood. Having more than 450,000 platelets is a condition called thrombocytosis; having less than 150,000 is known as thrombocytopenia.

What is the normal range for PTT and INR?

Normal Values for Coagulation Tests

What is normal aPTT level?

A normal range is around 21 to 35 seconds. But test results will vary depending on equipment and methods used. So standard normal results will differ in each lab. If your aPTT takes longer than normal, it may mean several things.

What are the 13 coagulation factors?

The following are coagulation factors and their common names:

• Factor I – fibrinogen.
• Factor II – prothrombin.
• Factor III – tissue thromboplastin (tissue factor)
• Factor IV – ionized calcium ( Ca++ )
• Factor V – labile factor or proaccelerin.
• Factor VI – unassigned.
• Factor VII – stable factor or proconvertin.

What does abnormal coagulation mean?

Coagulation disorders are disruptions in the body’s ability to control blood clotting. Coagulation disorders can result in either a hemorrhage (too little clotting that causes an increased risk of bleeding) or thrombosis (too much clotting that causes blood clots to obstruct blood flow).

What foods will increase platelet count?

Foods to eat to increase platelet count include: folate-rich foods. foods rich in vitamins B-12, C, D, and K….Folate-rich foods

• dark, leafy green vegetables, such as spinach and Brussels sprouts.
• beef liver.
• black-eyed peas.
• fortified breakfast cereals and dairy alternatives.
• rice.
• yeast.

What are normal lab values for coagulation studies?

Coagulation Studies Normal Lab Values. 1 Platelets (PLT) Platelets are produced in the bone marrow and play a role in hemostasis. Platelets function in hemostatic plug formation, clot 2 Activated Partial Thromboplastin Time (APTT) 3 Prothrombin Time and International Normalized Ratio (PT/INR) 4 Bleeding Time. 5 D-Dimer Test.

How is pt used in platelet and coagulation testing?

PT is used to measure the effectiveness of this therapy. Partial thromboplastin time, abbreviated as PTT, is a measurement that assesses the intrinsic and common pathways of the coagulation cascade.

Is there normal range of coagulation studies for not taking blood thinners?

There is a normal range of values in coagulation studies for people who are not taking blood thinners. 1 These ranges differ from the target values when a person is taking a blood thinner. Blood thinners and anticoagulants will make blood take longer to clot.

How are platelets and thrombocytopenia diagnosed in a CBC?

A CBC with platelet count, coagulation studies, and a peripheral blood smear are obtained. Excessive platelets and thrombocytopenia are diagnosed based on the platelet count; coagulation studies are normal unless there is a simultaneous coagulopathy. In patients with a normal CBC, platelet count, INR, and PTT, platelet dysfunction is suspected.
