Steroid isolation , depending on context, is the isolation of chemical matter required for chemical structure elucidation, derivitzation or degradation chemistry, biological testing, and other research needs (generally milligrams to grams, but often more [38] or the isolation of "analytical quantities" of the substance of interest (where the focus is on identifying and quantifying the substance (for example, in biological tissue or fluid). The amount isolated depends on the analytical method, but is generally less than one microgram. [39] [ page needed ] The methods of isolation to achieve the two scales of product are distinct, but include extraction , precipitation, adsorption , chromatography , and crystallization . In both cases, the isolated substance is purified to chemical homogeneity; combined separation and analytical methods, such as LC-MS , are chosen to be "orthogonal"—achieving their separations based on distinct modes of interaction between substance and isolating matrix—to detect a single species in the pure sample. Structure determination refers to the methods to determine the chemical structure of an isolated pure steroid, using an evolving array of chemical and physical methods which have included NMR and small-molecule crystallography . [2] : 10–19 Methods of analysis overlap both of the above areas, emphasizing analytical methods to determining if a steroid is present in a mixture and determining its quantity. [39]

Some bodybuilders and athletes use trenbolone esters for their muscle-building and otherwise performance-enhancing effects. [5] Such use is illegal in the United States and many other countries. The DEA classifies trenbolone and its esters as Schedule III controlled substances under the Controlled Substances Act . [18] Trenbolone is classified as a Schedule 4 drug in Canada [19] and a class C drug with no penalty for personal use or possession in the United Kingdom . [20] Use or possession of steroids without a prescription is a crime in Australia . [21] The infamous "duchess" cocktail administered to Russian athletes at the Sochi Winter Olympics consisted of oxandrolone , a metenolone ester, and a trenbolone ester. [22]

Estas pruebas se realizan en el consultorio de un alergólogo (especialista en alergias).
Prueba de pinchazo o raspado y prueba intradérmica
Durante estas pruebas, cuya aplicación demora de 5 a 10 minutos, se introducen de 10 a 50 alérgenos. En adultos, generalmente se aplican en el antebrazo. En niños se aplican en la espalda. Después se espera unos 15 minutos para ver si aparece una pequeña protuberancia roja donde se aplicaron los alérgenos.
La prueba del pinchazo o raspado y la prueba intradérmica pueden doler un poco. Si es sensible a alguno de los alérgenos, podría tener picazón donde se le aplicó.
