Melzer's reagent can be used to test whether spores are amyloid, nonamyloid, or dextrinoid . Spores that stain bluish-gray to bluish-black are amyloid. Spores that stain brown to reddish-brown are dextrinoid. This test is normally performed on white spored mushrooms. If the spores are not light colored, a change will not be readily apparent.
Further chemical tests are needed to prove that the substance is blood. Confirmatory tests are the tests required to confirm the analysis. Confirmatory tests cost more than simpler presumptive tests so presumptive tests are often done to see if confirmatory tests are necessary. Similarly, in medicine, a presumptive diagnosis identifies the ...

The Sargan–Hansen test or Sargan's test is a statistical test used for testing over-identifying restrictions in a statistical model. It was proposed by John Denis Sargan in 1958, [1] and several variants were derived by him in 1975. [2] Lars Peter Hansen re-worked through the derivations and showed that it can be extended to general non ...
