What affects INR Test results?

Several factors can influence INR test results, including the type and dosage of anticoagulant medications (like warfarin), dietary vitamin K intake, liver function, and the presence of certain medical conditions. Additionally, variations in laboratory techniques and equipment can lead to discrepancies. Changes in medications, illnesses, or lifestyle factors, such as changes in diet or alcohol consumption, can also impact INR levels. Regular monitoring and communication with healthcare providers are essential for maintaining appropriate INR levels.
