Is prothrombin time 10.8 normal

Prothrombin time of 10.8 seconds is generally within the normal range. Prothrombin time is an important indicator for evaluating exogenous coagulation function, with a normal reference value of 11-14 seconds. However, different laboratory testing equipment and reagents may result in slight differences in the reference range. Prothrombin time mainly reflects the activity of coagulation factors II, V, VII, and X, as well as fibrinogen levels. When the test result is 10.8 seconds, if the reference lower limit set by the laboratory is 11 seconds, it may indicate a slight increase in coagulation function, but it usually has no clinical significance. In healthy individuals without bleeding or thrombotic symptoms, such slight deviations may be related to recent diet, medication use, or physiological fluctuations. Increased intake of vitamin K, use of certain antibiotics, or technical factors during testing can all lead to results slightly lower than the reference value. In rare cases, shortened prothrombin time may be associated with hypercoagulability, such as early disseminated intravascular coagulation, certain malignant tumors, or genetic coagulation factor abnormalities. However, if there are no other abnormal coagulation indicators or clinical symptoms after a simple 10.8 second result, there is generally no need for special intervention. It is recommended to make a comprehensive judgment based on indicators such as activated partial thromboplastin time and platelet count, in order to avoid interpreting a single value in isolation. If there is a recent surgical plan or a family history of thrombosis, you can consult a doctor to see if further examination is needed. Daily attention should be paid to observing for abnormal bleeding or thrombosis symptoms, and avoiding taking drugs or health supplements that affect coagulation function without authorization. It is recommended to recheck coagulation function in the same laboratory during regular physical examinations to ensure comparability of results.
