In fecal specimens, the quantity of parasitic forms of protozoan and/or helminthic parasites is frequently insufficient to be seen under a microscope in direct wet mounts or stained smear preparations. The copromicroscopic approach becomes more sensitive in these situations since the concentration technique enhances the likelihood of finding parasite organisms.
Sedimentation and flotation are the two most often used methods for stool concentration. Due to their simplicity and low risk of technical error, sedimentation techniques are frequently used in general diagnostic laboratories.
These techniques are used in medical field to diagnose the patient suffering from a particular disease. Thus diagnosis is hastened by running a sedimentation technique.
