Von Willebrand Factor Test

VWF test results can change with age due to factors such as hormonal fluctuations and the natural aging process. Adolescents and older individuals may experience variations in VWF levels and function. Regular monitoring is essential to adapt treatment plans as needed and ensure that VWF levels are within a healthy range.

A Von Willebrand factor (VWF) test is a blood test that measures the level of VWF in your bloodstream. VWF is a protein that plays a crucial role in blood clotting, and a deficiency can lead to bleeding disorders. The test helps diagnose and monitor conditions like von Willebrand disease (VWD) and assess your bleeding risk.

During a VWF test, a healthcare provider will typically draw a blood sample from a vein in your arm. The sample is sent to a laboratory, where the level of VWF is measured. The test is relatively simple and safe, with minimal discomfort and minimal risk of complications.

The results of a VWF test show the amount and function of VWF in your blood. Abnormal results may suggest von Willebrand disease, a bleeding disorder. Low VWF levels or impaired VWF function can lead to bleeding problems, while high levels may indicate certain health conditions. Interpretation should be done by a healthcare professional.
