Test Comments: Help
Poor plasma anticoagulant response to activated protein C (APC resistance) is the most commonly observed inherited defect associated with thrombotic risk. The transition of guanine (G) to adenine (A) at position 1691 of the factor V gene causes substitution of glutamine for arginine at amino acid 506, resulting in Factor … View more

Assay limitations: Help
Analytical sensitivity is >99% for mutations within the coding sequence and intron/exon borders. Mutations that are outside the regions sequenced will not be detected. Rare polymorphisms within primer or probe regions may interfere with detection of gene variants. Clinical sensitivity for hemophilia B is > 99% for males and 97% … View more
