Test Overview
Test Methodology

Allelic Discrimination, Polymerase Chain Reaction (PCR)

Test Usage

Mutation detection in candidate gene for hereditary hemochromatosis.

Reference Range *

Interpretive report provided.

* Reference ranges may change over time. Please refer to the original patient report when evaluating results.

Test Limitations

This test will detect the C282Y and/or H63D variants. Other mutations in the HFE gene or other causes of hereditary hemochromatosis will not be detected. The results should be interpreted in conjunction with iron studies, family history and clinical findings. Full HFE gene sequencing and possibly deletion/duplication analysis may be considered if clinical suspicion of hereditary hemochromatosis remains high.

Specimen Requirements
Collection Instructions

Collect blood in a lavender top tube. Refrigerate and send intact blood or bone marrow specimen within 48 hours of collection.

Alternate Specimen
The preferred specimen is whole blood collected in EDTA (lavender top). However, ACD (yellow top) and heparin (green top) may also be accepted.
Contraindications
In the absence of specific information regarding advances in the knowledge of mutation characteristics for a particular disorder, the current literature indicates that genetic tests for inherited disease need only be conducted once per lifetime.
Normal Volume
6 mL EDTA (lavender) whole blood. Extracted DNA is also acceptable if extracted in a CLIA certified laboratory.
