Semiquantitation scoring of helminth eggs and Blastocystis spp.a

DensityHelminth eggs or larvae on a 10× wet prepn
Numerous/heavy/many≥10 eggs or larvae/field
Moderate3–9 eggs or larvae/field
Scanty/light/few≤2 eggs or larvae/5–10 fields
Rare/occasional2–5 organisms/entire 22- by 22-mm coverslip area
  • a Although Blastocystis spp. can be seen on a wet mount, the overall morphology, ability to find the organisms, and quantitation are enhanced from the permanent-stain smear (5).
