English term or phrase:fecal float
Provtagning av hund och katt (tarmparasiter).
I texten förekommer "fecal smear" och "fecal float". Jag måste skilja på begreppen - det är inte tillåtet att gena.
"the ease of faecal floats/smears with the accuracy of a reference laboratory."
"In-House Microscopy (Faecal Float)"
"As an adjunct to faecal float parasitic diagnosis —
if you’re looking for intestinal parasites, don’t miss
a Giardia infection."
Ytterligare info från kunden:
"Both techniques are qualitative fecal examinations (not quantitative). The faecal smear consists in "obtaining a direct smear made by breaking up a very small particle of feces in a drop of saline". Once you smear the fecal
sample on a slide you can then observe it at the microscope. Is a very simple technique but its efficiency is limited because only a small particle of feces can be examined, and if a small amount of parasites is present on the sample then maybe you could obtain a false negative. To avoid this, some
concentration techniques appeared ie: faecal flotation
"If the number of parasites in the stool specimens is low,examination of a direct wet mount may not detect them, hence the stool should be concentrated. This makes direct wet mount examination obligatory as the initial phase of microscopic examination [...]. Flotation procedures: In
which the eggs and cysts float at the surface due to specific gravity gradient.
Faecal float is a more sensitive technique, as it is to concentrate the fecal sample taking advantage of a difference in the buyancy of parasites relative to food residus. After concentration (using ie: a concentrated
sucrose solution) you scan an slide of the concentrated sample on the microscope."
Det framgår alltså tydligt vad det handlar om, men jag är tacksam för hjälp med terminologin!
