7.4 Sample Collection and Use of Preservatives in Poisoning Cases

The toxicology's samples (the LAW5510-U7.4's medical application): the living's samples: the vomitus-and-gastric-lavage; the blood (the quantitative); the urine (the screening); the hair (the chronic). The dead's samples: the viscera's trio (the stomach-and-contents; the liver; the kidney- and-blood) + the urine, the vitreous, the hair; the preservatives: the saturated-sodium-chloride (the viscera's classic); the sodium-fluoride (the blood — the alcohol's preservation-and-the- fermentation's stop); the plain-container (the corrosives' — the glass's non-reactive duty; no plastic with the solvents); the discipline: the sterile-and-sealed containers; the labelling; the chain; the laboratory's earliest transmission (the decay's faces).
