About Us

Materials Reactivity Test

We are happy to offer a Clifford Materials Reactivity Test through ELISA/ACT Biotechnologies

In modern society we come in contact with many substances every day in the environment, the food we eat, the products we use and the treatments we receive.

Because each of us possesses unique chemical sensitivities, these substances affect each of us differently and in varying degrees. For some, the effects of certain substances (and their corrosion byproducts) can be toxic and hazardous, and may result in serious health problems. A substance which causes little or no reaction in one individual can prove harmful to another.

Since these effects may vary in each of us, it is vital that these material sensitivities be considered when choosing dental and other materials for use in the body, especially in patients with rare or unique health concerns.

Materials Reactivity Test

Clifford Materials Reactivity Testing (CMRT) provides dentists and physicians with extensive information about their patients individual sensitivities so that least offensive materials can be chosen and used in their treatments

CMRT is not merely based upon the body’s response to biomaterials themselves, but also upon response to corrosion byproducts of those materials. These byproducts are generated at various rates as the materials decompose or break down in the body. It is these products of decomposition that the body must deal with and which are most likely to cause untoward health effects and toxic conditions. The body produces systemic antibodies against challenging antigens and will maintain an immunologic record of the components or chemical families which have proven offensive and which can be observed by CMRT.

Clifford Materials Reactivity Testing (CMRT) is a laboratory screening test used to help identify existing sensitivity problems to various chemical groups in an individual patient. This test is currently offered in Dental and Orthopedic panels. The same 94 chemical groups are tested in both panels, but correlated with different databases of products depending on the panel ordered. The Dental panel reports on over 17,204 trade-named dental products. The Orthopedic panel reports on over 10,427 trade-named products for surgical applications.

CMRT National Provider (NPI) is 1316110588

CMRT Clinical Laboratory Improvement (CLIA) Number is 06D0669295

Test Kits must be picked up from our office.

Payment due to ELISA/ACT Biotechnologies.
