On a UA, is it usually the shield that they turn through the trouble of identify specific opiates/opioids, OR?
You don't get Thebaine from Codeine, but you do attain Morphine, etc.....
Answer:
To identify the specific compounds (e.g., which opiate) involves an additional step to be exact both expensive and relatively-time consuming, though not for the patients. The toxicology screens simply identify adjectives areas on the compounds in ask, so cannot discriminate among which opioids might be present (and, in reality, my test "positive" next to other substances that have chemical region similarities).
To specifically identify the compound would require an superfluous specific step, such as chromatography (gas or HPLC).
Clinically, this is rarely needed, though at hand are times when medical practice and legal issues overlap and might necessitate the specific permit of anything found in the screening test.
There is a nice summary overview on Medline that I've linked below.
Depends entirely on the entity that perform the analisys. random coloring decide the presence of the drug, other depths of colors and random colors communicate the level and associations near them.
