Fibrinogen
Also known as: FIB
Use
This test is used to determine if fibrinogen deficiency is a potential cause of bleeding. Fibrinogen is a critical protein involved in blood clotting, and its deficiency can lead to bleeding disorders. Measuring fibrinogen levels helps in diagnosing potential bleeding issues and assessing the overall clotting function of a patient's blood.
Special Instructions
Separate specimens must be submitted when multiple tests are ordered. Ensure the specimen is frozen critically to maintain test accuracy. Refer to ARUP's Hemostasis/Thrombosis specimen handling guidelines for detailed instructions.
Limitations
Serum and EDTA plasma specimens are unacceptable for this test, along with any clotted or hemolyzed specimens, which may lead to inaccurate results. Refrigerated specimens are also deemed unacceptable, highlighting the importance of following handling instructions precisely to avoid rejected submissions and ensure accurate testing outcomes.
