False-negative factor V Leiden genetic testing in a patient with recurrent deep venous thrombosis.

American journal of hematology - 1 Apr 2006

Abstract excerpt

False-negative genetic testing of the factor V Leiden (fVL) mutation is unusual. We report a case of a young woman with a history of deep venous thrombosis tested for the fVL at four separate laboratories on four separate dates. Two laboratories reported the patient to be heterozygous for the fVL, while the other two reported no evidence of a mutation. Testing methods of the various laboratories were reviewed,...
