Abstract
Background and Objectives
FVIII activity (FVIII:C) is measured by clotting or chromogenic methods. The results of these methods may be different in some cases of hemophilia A that can cause misdiagnosis. The Aim of this study is to assess the results of two methods of F VIII:C assay in patients with hemophilia A.
Materials and Methods
In A descriptive survey research, FVIII:C level was measured using one-stage and chromogenic assays in 73 hemophilia A known patients. The data were analyzed by t-test and SPSS 22 statistical method.
Results
From 73 patients in this study, the range of FVIII:C assay by one-stage method was 4% to 81% ( mean = 22.7 , SD = 14.8 ) and the range of FVIII:C assay by chromogenic method was 1% to 123 % ( mean=16.5 , SD = 21 ).
Conclusions
For prevention of misdiagnosis, it is recommended to use two methods of FVIII:C assays for diagnosis of patients with hemophilia A.
