ROSA Test is a qualitative colorimetric test for the dosage of nitric oxide on saliva through the determination of nitrites, its direct precursors, since the direct measurement of NO is very difficult in vivo.

Through this test is therefore possible to suppose an inflammatory condition caused by a bacterial infection of the oral cavity (e.g. periodontitis), pharynx (e.g. angina streptococcal) or stomach (e.g. colonization by Helicobacter pylori).


The test is performed on a saliva sample and DOES NOT REQUIRE ANY INSTRUMENTATION.
