UBiome(YC S14) tests for hypothetical health conditions

uBiome (YCS14) unveils its new CLIA and CAP certified medical test. They claim it tests for a variety of conditions, including 'leaky gut syndrome.' Wikipedia describes leaky gut as 'a hypothetical, medically unrecognized condition.' How is it possible to have CLIA and CAP certification for this? I haven't seen any peer reviewed data from them period. Can anybody point me to a paper?
