Assessing Coagulation Factor Dynamics for Comprehensive Hemostasis Evaluation
The factor IX test is part of a larger screening test to find out what type of bleeding disorder you have. Factor IX is a protein that helps your blood clot. If you are lacking this protein, you may have a bleeding disorder called hemophilia B. Hemophilia B is found mostly in males.

How our test process works!
Overview
Factor IX is a clotting protein in the intrinsic pathway of coagulation. The Factor IX test measures its level or activity in blood to help diagnose bleeding disorders, especially Hemophilia B and other coagulation abnormalities.
Indications / Risk Assessment
The test is recommended for:
-
Unexplained bleeding or bruising
-
Suspected Hemophilia B (Christmas disease)
-
Family history of bleeding disorders
-
Pre-operative bleeding risk assessment
-
Monitoring after Factor IX replacement therapy
-
Investigation of prolonged APTT
Normal Range
-
50% – 150% activity
(Values may vary slightly by laboratory)
Interpretation
Low Factor IX Level:
-
Suggests Hemophilia B
-
Can occur in vitamin K deficiency, liver disease, warfarin therapy, DIC, or acquired inhibitors
High Factor IX Level:
-
May be seen in inflammation, pregnancy, oral contraceptive use, or thrombophilia risk
(High Factor IX can increase risk of thrombosis)
Sample Type
-
Citrated plasma
(Collected in a blue-top sodium citrate tube)
