Low prothrombin time suggests a possible "hypercoagulable" state, where blood clots more quickly than usual. This can cause problems with blood clots in veins in the legs, pelvis, or abdomen, or in arteries in the heart, neck, or brain, which can lead to venous thrombosis clot fragments going to the lungs (causing pulmonary embolism) or heart attack or stroke.

What else can I help you with?
Blood protein such as prothrombin are produced by the?
Liver.
What type of globulin is prothrombin?
an alpha-globulin produced in the liver to initiate the coagulation cascade
What is the slowest step in the clotting process?
The activation of factor X to Xa is typically considered the slowest step in the clotting process. This step involves multiple protease activations, which can take more time compared to other steps in the clotting cascade.
What are causes of low albumin?
Low albumin levels can be caused by conditions that affect the liver, such as cirrhosis or hepatitis, as albumin is produced in the liver. Other causes can include malnutrition, kidney disease, and inflammatory conditions like rheumatoid arthritis or inflammatory bowel disease. Additionally, conditions that increase loss of albumin, such as kidney diseases or severe burns, can also lead to low levels.
Why does your skin get wrinkly in water due to osmosis?
When your skin is in water for a long time, the outer layer absorbs water and swells up. This causes the skin to wrinkle due to osmosis, where water moves from an area of low concentration to an area of high concentration.
How aspirin causes increased prothrombin time?
It decreases synthesis of thromboxane A2 and prostaglandins to increase bleeding time. It does not affect PT or PTT. Prothrombin time unaffected!
What causes hypoprothrombinemia?
inadequate synthsis of prothrombin
What is prothrombin time INR lab test?
The INR has basically replaced the prothrombin time, or PT.
What are the Diagnostic procedures for acute prothrombin complex deficiency?
prothrombin time, hematocrit
What causes pro-time levels to be too low?
Low prothrombin time (pro-time) levels can be caused by conditions such as liver disease, vitamin K deficiency, or use of certain medications like anticoagulants. It can also be due to clotting factor deficiencies or abnormalities in the intrinsic or extrinsic clotting pathways.
What is a pti bloodtest?
prothrombin time
What is normal prothrombin time?
10-13 sec
Can vitamin k correct prothrombin time in hepatocellular jaundice?
Vitamin K corrects prothrombin in the setting of biliary obstruction but not of hepatocellular damage.
What coagulation factors are measured by the PT?
Prothrombin time (PT) measures the activity of coagulation factors in the tissue factor pathway of the coagulation cascade.
Liver synthetic capability tests?
albumin and prothrombin time...
What happens to someone if they have a prothrombin deficiency?
Prothrombin deficiency causes prolonged bleeding following even minor injury or trauma. In sufferers the blood clotting process is slowed, and in severe cases spontaneous bleeding can occur.
Which blood test evaluates the clotting ability of the blood?
Prothrombin time
