How do you interpret TEG results?
If we interpret our TEG values: R time 20.0 => well above the upper limit of normal (10.0 minutes) = significantly prolonged time for clot formation. K time 13.2 => normal: up to 10.0 = prolonged fibrin cross-linking. a-angle 16.5 => normal >53.0 = limited clot formation.
What is a normal TEG?
Approximate normal values (kaolin activated TEG, values differ if native blood used, and between types of assay) R: 4-8 min. K: 1-4 min. α-Angle: 47-74° MA: 55-73mm.
What are TEG values?
TEG-ACT is the activated clotting time (CT) for the rTEG, with normal values ranging from 80 to 130 seconds. The K-time (normal range, 1 to 2 minutes with rTEG and 1 to 3 minutes with standard TEG) is the time needed to reach 20 mm clot strength; this is generally increased in states of hypofibrinogenemia.
Is TEG a point of care test?
Point-of-care tests
The two most common POC testing platforms in clinical use are the viscoelastic tests ROTEM and TEG.
What is TEG platelet mapping?
The whole blood TEG® Platelet Mapping™ assay measures clot strength as maximal amplitude (MA) and enables for quantification of platelet function, including the contribution of the adenosine diphosphate (ADP) and thromboxane A2 (TxA2) receptors to clot formation.
What is a TEG trauma?
TEG is a bedside test that is useful in the setting of ‘controlled’ hemorrhage, such as liver transplant and cardiac surgery. In trauma, bleeding can occur at such a pace that the TEG result may lag behind the clinical situation, leading to delayed and inappropriate therapy.
When do you use TEG?
There are multiple applications of TEG in clinical care including but not limited to surgical and trauma patients, liver transplantation, acute and chronic liver disease, optimal blood utilization, coagulopathies (like hemophilia), cardiac bypass, sepsis, pregnancy and postpartum hemorrhage, neonatal care, veterinary …
What is maximum amplitude TEG?
Maximum Amplitude (MA)
A function of the maximum dynamic properties of fibrin and platelet bonding via GPIIb/IIIa and represents the strongest point of fibrin clot and correlates to platelet function: 80% platelets; 20% fibrinogen.
What is a TEG study?
TEG is a non-invasive test that quantitatively measures the ability of whole blood to form a clot. The principle of this in vitro test is to detect and quantify dynamic changes of the viscoelastic properties of a blood sample during clotting under low shear stress.
What is the difference between TEG and Rotem?
A pin is suspended into the cup, and then some sort of rotation takes place. In fact the main difference between TEG and ROTEM is the bit which rotates (TEG rotates the cup, and ROTEM rotates the pin). Irrespective of which bit is rotating, some impediment to the rotation develops as the blood clots.
How do you check platelets function?
Most platelet tests are done on a blood sample. During the test, a health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial.
How much does a TEG test cost?
These tests are also costly and take a long time for results. TEG could potentially replace PT/INR, PTT, and platelet function tests ▪ Together, all of these tests cost over $500!
How long does a TEG test take?
Each TEG run generally takes 30 minutes to an hour to complete and only a few cases can run simultaneously, unlike conventional lab coagulation testing. Therefore, optimization of TEG use is an important concern in providing appropriate patient laboratory testing.
When is TEG used?
Thromboelastography (TEG) is a method of testing the efficiency of blood coagulation. It is a test mainly used in surgery and anesthesiology, although increasingly used in resuscitations in Emergency Departments, intensive care units, and labor and delivery suites.
How long does it take to run a TEG?
What is TEG in cardiac surgery?
Complex cardiac procedures often require blood transfusion because of surgical bleeding or coagulopathy. Thrombelastography (TEG) was introduced in our institution to direct transfusion management in cardiothoracic surgery.
What is the alarming level of platelets?
Dangerous internal bleeding can occur when your platelet count falls below 10,000 platelets per microliter. Though rare, severe thrombocytopenia can cause bleeding into the brain, which can be fatal.
What is the most common platelet disorder?
The most common types are:
- Bernard Soulier disease.
- Glanzmann’s thrombasthenia.
- Hermansky Pudlak syndrome.
- Jacobsen syndrome.
- Lowe syndrome.
- Platelet release and storage pool defects.
- Thrombocytopenia with absent radius (TAR) syndrome.
- Thrombotic thrombocytopenic purpura (TTP)
What is a rapid TEG?
This assay incorporates tissue factor to the whole blood sample immediately before test initiation to expedite results, also known as Rapid-TEG (r-TEG).
How do you do TEG?

What cancers cause low platelets?
Certain cancers such as leukemia or lymphoma can lower your platelet count. The abnormal cells in these cancers can crowd out healthy cells in the bone marrow, where platelets are made.
Can vitamin D deficiency cause high platelet count?
Increased platelet counts were found in people with low vitamin D levels.
What are symptoms of a platelet disorder?
Symptoms of platelet disorders include blood clots, bleeding, and bruising. You may not have any symptoms if your platelet count is not very high or very low. Your healthcare provider will diagnose your platelet disorder based on your medical history, a physical exam, and blood tests.
What is the most common cause of low platelet count?
Decreased production of platelets
Some types of anemia. Viral infections, such as hepatitis C or HIV. Chemotherapy drugs and radiation therapy. Heavy alcohol consumption.
Can Vitamin B12 deficiency cause high platelet count?
An elevated platelet count can be temporary resulting from things such as excessive alcohol use, vitamin B12 deficiency, acute infection, or strenuous activity.
