Diagnostic Parasitology: Fecal Samples (Common Floatation Solution for The Fecal Flotation Technique & Diagnostic Techniques)
DIAGNOSTIC PARASITOLOGY: FECAL SAMPLES (Common Floatation Solution for The Fecal Flotation Technique & Diagnostic Techniques) Diagnostic of parasitic infection depends on several factors, such as collection of samples, transport of samples to laboratory, and method of laboratory evaluation. Feces must be fresh for accurate result . As feces age, a diagnosis is complicated because many parasite eggs develop and hatch into larvae. Contaminants such as free-living soil nematodes, fly larvae, mites, and other arthropods often invade feces and complicate a diagnosis. At least 10 g of fresh feces should be collected. If samples are more than two hours old, samples should be stored at 4 degrees C until examined. Many parasite stages can be stored at 4 degrees C for at least two months with minimal development For routine shipment to laboratory , samples can be cooled to 4 degrees C and then packed with ice or other coolant (blue ice) for shipment via any of the 24- to 48
