Prothrombin Fragment 1+2
Use
Evaluation of F 1+2 in plasma is a determinant of in vivo thrombin generation.
Special Instructions
Not provided.
Limitations
Traumatic venipuncture or prolonged stasis may invalidate results. Improper mixing of the specimen after venipuncture can falsely elevate F 1+2 levels. The test may be influenced by improper specimen collection techniques, such as drawing from an arm with a heparin lock or heparinized catheter.
