Whole Genome Sequencing
Ordering Recommendation
Preferred test to determine the etiology of a patient’s symptoms if a Mendelian genetic condition is suspected. Parental control specimens are recommended for this test; order Whole Genome Sequencing, Familial Control (3016497). Submission of a completed Whole Genome Sequencing Intake Form is required for the proband.
To compare this test to other exome/genome testing options, refer to the ARUP Genome and Exome Sequencing table.
New York DOH Approval Status
Specimen Required
Lavender (EDTA) or pink (EDTA). Peripheral blood required. Contact ARUP's genetic counselor at 800-242-2787 ext. 2141 prior to test submission. Refer to Whole Genome Sequencing, Familial Control (ARUP test code 3016497) for parental specimen requirements. Two parental controls are recommended for optimal whole genome analysis.
New York State Clients: ARUP cannot facilitate testing for New York patients. Please work directly with a New York-approved laboratory.
Transport 2 mL whole blood. (Min: 1.0 mL) Refer to Whole Genome Sequencing, Familial Control (ARUP test code 3016497) for parental specimen requirements.
Refrigerated. Refer to Whole Genome Sequencing, Familial Control (ARUP test code 3016497) for parental specimen requirements.
When ARUP is requested to initiate preauthorization, DNA extraction will be performed on the proband and comparator samples to ensure sample stability (DNA Extract and Hold, ARUP test code 3005714, will be added to each sample by ARUP, additional charges apply). The cost of DNA extraction is credited when genome sequencing is performed.
