Overview of the Factor VIII Assay
The Factor VIII Assay measures the activity of Factor VIII, an essential blood clotting protein involved in the coagulation cascade. Factor VIII works alongside other clotting factors to help form stable blood clots following injury, helping to control bleeding and support normal haemostasis.
This is a single-biomarker coagulation test that measures Factor VIII activity. It is commonly requested during specialist investigations of bleeding disorders, abnormal clotting results, or as part of the assessment of inherited or acquired coagulation abnormalities. It may also be used to monitor certain conditions or treatments under the supervision of a haematologist.
People may choose this test if they have experienced unusual bleeding, prolonged bleeding following surgery or dental procedures, unexplained bruising, a family history of clotting disorders, or if a healthcare professional has recommended further investigation of blood clotting function.
The Factor VIII Assay provides valuable laboratory information but does not diagnose a bleeding or clotting disorder on its own. Results should always be interpreted alongside symptoms, medical history, medications, family history and other coagulation investigations by a suitably qualified healthcare professional.
What Does the Factor VIII Assay Check ?
Factor VIII Assay - Factor VIII is a clotting protein produced mainly in the liver and carried in the bloodstream by von Willebrand factor. It plays a vital role in the blood clotting process by helping activate other clotting proteins to form a stable blood clot. Measuring Factor VIII activity helps assess how effectively this clotting factor is functioning and may contribute to the investigation of bleeding disorders or coagulation abnormalities.

When Will I Receive My Results?
Results are typically available within 7 days after the laboratory receives your sample.
Once authorised by the laboratory, your report will be sent securely by email.
Turnaround times begin when the laboratory receives your sample rather than when it is collected. Specialist coagulation testing may occasionally require additional processing time. Results outside the expected range should be reviewed with a GP, haematologist or other suitably qualified healthcare professional.
Understanding Your Results
Your report will include your Factor VIII activity together with the laboratory reference range and any relevant interpretative comments.
Reference ranges may vary slightly between laboratories because of differences in testing methods and equipment. A normal result does not always exclude a bleeding disorder, while an abnormal result does not automatically confirm a diagnosis.
Your results should always be interpreted alongside symptoms, medical history, medications, family history and other coagulation investigations. If you have concerns regarding your results, discuss them with your GP, haematologist or another qualified healthcare professional.
