Cryofibrinogen, Qualitative

Sample type:

• Blue-top (sodium citrate) tube, lavender-top (EDTA) tube, or gray-top (sodium fluoride) tube.

Uses:

• This test looks for an abnormal protein called cryofibrinogen in your blood plasma.

• People who have this abnormal protein may get a disorder called cryofibrinogenemia. The disorder rarely causes symptoms. But if it’s not treated, it can become life-threatening and lead to stroke, heart attack, gangrene, or other health emergencies.

Precautions:

• Specimen must be drawn in a prewarmed tube and kept at 37°C.

• Separate plasma from cells immediately, and transfer the plasma into a clean transport tube.

Interfering Factors:

• If you are taking a blood thinner containing heparin, you may get a false-positive test result.

• Test results may vary depending on your age, gender, health history, the method used for the test, and other things.

• Be sure your healthcare provider knows about all medicines, herbs, vitamins, and supplements you are taking. This includes medicines that don’t need a prescription and any illicit drugs you may use.
