![]() One thing came to mind after I left the hematologist’s office. ![]() I had a bi-lateral pulmonary embolism about nine months ago and it is very important for me to maintain that level. All of a sudden, this past month it plummeted to 1.7, which puts me at a dangerous risk for clotting. For 9 months, my PT INR count has been therapeutic, ie, 2.3 to 2.8. ![]() Patients need to talk with their doctors on how to keep the PT INR levels in check. PT INR normal values are very important in gauging the chances of stroke and bleeding. Laxatives and alcoholic beverages can also result in abnormal PT INR levels. Some of these foods are green tea, chickpeas, soybean products, turnip greens, broccoli, pork liver, beef liver and kale. Herbal products can also make PT INR levels to become abnormal.ĭehydration, which can be due to vomiting and diarrhea, can also result to false reading of PT INR.Ĭonsumption of foods high in vitamin K before the PT INR test will result in false-positive PT INR test result. These include antibiotics, cimetidine, vitamin K supplements, aspirin, barbiturates, hormone replacement therapy and oral contraceptives. Some medications can influence the effects of vitamin K and anticoagulants in a person’s body. It is possible for false reading of the PT INR test result to occur, and this could be due to various factors such as: Is false reading of PT INR test result possible? The doctor may conduct further testing if the underlying cause of abnormal PT INR level is not established. Consuming foods that alter the effects of anticoagulant medications.Certain medications such as cold medicine, supplements, vitamins, oral contraceptives, antibiotics and hormone replacement therapy.There are several reasons why PT INR values become abnormal, and this could be due to: On the other hand, if the PT INR values are found on the lower end of the spectrum, inappropriate blood clotting may occur. If the PT INR values are found on the higher end of the normal range, bleeding and other related events will likely occur. This is because an abnormal PT INR value is a strong indication that there is a higher possibility for stroke or bleeding to occur. People who fall short in reaching PT INR normal values should be wary. The doctor will be the one to determine the ideal PT INR value for his or her patient. Normal PT INR range for people not taking anticoagulants – 0.8 to 1.2.Normal PT INR range for people taking anticoagulants – 2.0 to 4.0.Normal PT INR values also differ between those who take anticoagulants and those who do not. The PT INR normal values differ for every individual and depending on a number of factors including medical conditions that result in taking anticoagulants. The frequency of PT INR test differs with every individual, though most often it is done once in every 4 or 6 weeks. The finest way patients can determine their PT INR levels is to have it checked by a laboratory or through commercially available self-testing kits. Stroke is the number one cause of disability in adults and ranked as the third cause of high mortality among Americans. Maintaining PT INR normal values is extremely important to avoid the dreadful and serious complications that may occur due to abnormal PT INR levels which could result into dangerous blood clotting or excessive bleeding. ![]() How important is it to maintain PT INR at normal levels? The test is also conducted when the patient is schedules to go through a surgical procedure to determine the blood clotting ability of the patient. PT INR test is also done to those who exhibit bleeding disorder symptoms which is characterized by bleeding gums, nosebleeds, bruising, bloody stool and urine, heavy menstrual flow, chronic anemia, vision loss and arthritic-type symptoms. People who receive artificial heart valves also receive anticoagulant therapy. Anticoagulants are utilized to prevent inappropriate and dangerous blood clotting which may lead to heart attacks, strokes, cerebrovascular accidents and deep vein thrombosis. The test is primarily done to patients who are receiving anticoagulant therapy. PT INR normal values are helpful guidelines when interpreting the PT INR test result. There are various ways to test PT and because of the differences of testing methods used by laboratories, INR or international normalized ratio is used to standardize the PT test results. PT refers to prothrombin time, a type of blood test that measures a person’s blood clotting time. PT INR normal values slightly differ between clinical laboratories. ![]()
