Order TestThere are multiple options to initiate the Phosphorus testing process. Phosphorus can send you a kit with all of the materials to collect and ship a specimen or you can download the required forms and ship the specimen. Specimens can be collected via blood or saliva samples.
For clinics located in the United States, our kits include a prepaid Fedex return envelope which allows you to return the sample to our laboratory at no cost.
