How to Order

NantHealth molecular tests can only be ordered by a physician. GPS Cancer and Liquid GPS can be ordered individually, or physicians can select GPS Complete to order both tests concurrently. This combined option provides comprehensive tissue and blood-based profiling to inform initial treatment selection, as well as important baseline measurements of blood-based biomarkers to support ongoing monitoring of response or resistance to treatment.

If you would like more information or assistance with the ordering process, please contact the GPS Care Center at 1-844-MY-OMICS or email us at
