Since VirtuOst is only available by prescription, you must be a physician or qualified healthcare professional to place an order. To order a VirtuOst test from the O.N. Diagnostics IDTF, please request the VirtuOst Order Packet by filling out the form below and we will confirm your request by return email. This electronic packet includes information about the VirtuOst tests, VirtuOst order forms, and an order checklist with instructions. You can also request us to send you hardcopy brochures for discussing VirtuOst BCT with your patients.
