Detects sequence variants in the Transthyretin (TTR) gene.

Please label each specimen tube with two forms of patient
identification. These forms of identification must also appear on the
requisition form. Higher blood volumes ensure adequate DNA quantity,
which varies with WBC, specimen condition, and need for confirmatory
testing.

Specimen Note:
DNA yields and quality are better in fresh specimens. However, when
necessary, most genetic tests are successful from DNA purified from
whole blood that is several days old.
