Tests conducted to identify parasites in feces include:
- Qualitative and quantitative centrifugation concentration flotation techniques
- Antigen capture ELISA tests for Giardia and Cryptosporidium
- Nematode larvae cultures
- Direct fecal smears (wet mounts)
- Baermann technique for recovery of nematode larvae
Test conducted to identify parasitic infections using serum include:
- Occult heartworm test
- Toxoplasma modified agglutination technique (MAT)
- Feline antibody heartworm test
Other tests conducted include:
- Knott’s technique for microfilariae in blood
- Parasite identification - whole parasites, on histological slides, in a biopsy
- Tritrichomonas foetus InPouch culture test
- KOH digestion of skin scrapings to retrieve ectoparasites
- Whirling Disease testing of fish
- Sand recovery analysis for horses
Samples received for examination include feces, blood, urine, tracheal washes, duodenal aspirates, skin scrapings, entire endo- and ectoparasites, necropsy samples, feed samples , and environmental samples such as soil and composted material.
If it is deemed necessary for confirmation of identification, stains may be used, i.e., Kinyoun modified acid-fast stain, Lugol’s iodine, Giemsa stain, and immunofluorescent stains for Giardia and Cryptosporidium.
