Cautions

Pre-analytical conditions such as a difficult draw may spuriously increase test results.

 

Improper collection of the sample or insufficient mixing of the sample and anticoagulant in the collection tube can lead to falsely elevated F1+2 values. 

 

As with all tests containing monoclonal mouse antibodies, erroneous findings may be obtained from samples taken from patients who have been treated with monoclonal mouse antibodies or who have received them for diagnostic purposes.
