Workup

Laboratory Studies

The following are laboratory studies used in the diagnosis of whipworm infection (trichuriasis):

  • Studies often reveal eosinophilia from ongoing tissue invasion (in contrast to all intestinal helminths except Strongyloides stercoralis).
  • Rarely, studies show anemia.
  • Characteristic eggs on stool smear (oval with transparent bipolar plugs) are visible.
  • Each female produces up to 20,000 eggs per day. (No stool concentration technique is necessary.)
