Mimicking Protozoa The most common structures misidentified as protozoan parasites are human cells, yeasts, and starch grains. 4,5 [T2] provides a comparison of these cells with the more common protozoa with which they are confused.
What can be mistaken for parasites in stool?
Plant hairs can be common in stool and may be confused for the larvae of hookworm or Strongyloides stercoralis. However, they are often broken at one end, have a refractile center and lack the strictures seem in helminth larvae (esophagus, genital primordium, etc).
How do you know if you have a parasite or not?
Fecal testing (examination of your stool) can identify both helminths and protozoa. Stool samples must be collected before you take any anti-diarrhea drugs or antibiotics, or before x-rays with barium are taken. Several stool samples may be needed to find the parasite.
How do you rule out parasites?
By looking at a blood smear under a microscope, parasitic diseases such as filariasis, malaria, or babesiosis, can be diagnosed. This test is done by placing a drop of blood on a microscope slide. The slide is then stained and examined under a microscope.
What is the easiest way to identify parasites?
The diagnosis is established by identification of parasite eggs in the urine or biopsy specimens or by serologic findings. Urine specimens collected for identification of eggs should be obtained on consecutive days between 1100 and 1300 hours because egg passage is maximal at this time.
