LOINC long common name : F5 gene HR2 haplotype [Genotype] in Blood by Molecular genetics method Nominal;
LOINC short name : F5 HR2 Geno Bld;
LOINC description : Factor V HR2 Allele, DNA Mutation Analysis is useful in patients who are carriers
of Factor V Mutation (Leiden)as coinheritance of Factor V Mutation (Leiden) is associated
with a 3-4-fold increased risk of venous thrombosis compared to inheritance of Factor
V Mutation (Leiden) alone. As a result the result of the HR2 haplotype analysis is
interpreted in the context of knowledge of the Leiden mutation.;
