Combo Test Kit

The combo test kit combines both saliva and blood spot test collection materials in an all-in-one kit, allowing for a single, comprehensive report. Putting saliva and blood spot test materials together in one combination kit makes it convenient to collect hormones from the three major glandular systems - reproductive, thyroid, and adrenal - on the same day at the optimal time.

While the combo test kit provides the best overall value, Blood Spot Tests and Saliva Tests are also available as individual kits. See the comparison chart in the tab below for more information.
