Office parasitology.
The family physician often lacks the training needed to make a definitive diagnosis from parasitic findings. The transparent adhesive tape test or a smear made from digital rectal examination is frequently helpful in the diagnosis when microscopic examination is carefully done. Stool examination may be necessary. All of the intestinal nematodes that commonly occur in the United States can be identified by simple office techniques and careful microscopic study. The eggs are readily seen under low-power magnification. Intestinal protozoa require more practice and patience, and correct species identification is mandatory.
