In cold weather, add 1 part ethanol to 9 parts 10% buffered formalin to prevent freezing during transit.

A sedimentation technique is used to concentrate trematode eggs (flukes) such as Fasciola hepatica, Fascioloides magna, and Paragonimus.

Send samples on ice pack in a leak proof container. Overnight or 2 day shipping is recommended.

Aerobic culture including assessment of normal enteric flora and special culture for Salmonella sp. Antimicrobial susceptibility testing is not routinely performed on bacterial isolates from enteric sources due to lack of in vivo efficacy. Samples from different animals will not be pooled for culture. For small animals see Fecal culture (small animal).

Includes special cultures for Salmonella sp., Camplyobacter sp. and Yersinia sp. Antimicrobial susceptibility testing is not routinely performed on bacterial isolates from enteric sources due to lack of in vivo efficacy. For large animals see fecal culture (large animal).

Identification of protozoan trophozoites and cysts. Direct smear is ideal for protozoans that float poorly or are readily distorted by flotation solutions.

Submit samples on ice within one day of collection whenever possible.

Very little fecal material is used for this procedure, therefore, the sensitivity of this test is low. It is not recommended for routine fecal examinations.

The McMaster fecal analysis is a quantitative analysis designed to determine the presence or absence of strongyle and ascarid eggs expressed as eggs per gram through a controlled sampling of feces.

Submit samples on ice within one day of collection whenever possible.

Centrifugal flotation method for qualitative (parasites present or absent) analysis of fecal material to determine the presence of parasite eggs (nematodes, cestodes, trematodes) as well as the presence of coccidia (Eimeria, Isospora). Relative quantities of parasites are not provided as part of the test result.

If quantitation of Stongyle type eggs is desired, please request a McMaster’s Egg Count.

Submit samples on ice within one day of collection whenever possible.

Dried samples, such as those submitted on a swab, are unacceptable for examination and will be rejected.

Spleen, lymph node, kidney, omentum, liver, brain, EDTA whole blood (1 ml minimum)

This assay targets the RNA of a portion of the 7b gene from Feline coronavirus. This assay cannot distinguish between FIPV (feline infectious peritonitis virus) and FECV (feline enteric coronavirus); therefore, a FIP diagnosis should also take into account other diagnostic tests including case history, hematology, and histopathological examination of biopsies.

Feline

To ensure inclusion in the test run, samples should arrive the day prior to test day.

Test can be performed on EDTA whole blood but it is not recommended. Detection outside of the intestinal tract supports a FIP diagnosis. Care should be taken such that samples remain uncontaminated by fecal material.

Detection of feline herpesvirus by fluorescent antibody (FA) testing.

Feline

Detection of feline panleukopenia virus by fluorescent antibody (FA) testing.

Feline

Canine: Lung, liver, spleen, kidney, heart | Feline: Cerebellum

This assay targets the DNA of a portion of the VP2 gene from Canine parvovirus-2 and Feline Panleukopenia virus. This assay cannot differentiate CPV-2 and FPLV. The virus is usually only detectable in the feces for up to 2 weeks after infection.

Feline | Canine

To ensure inclusion in the test run, samples should arrive the day prior to test day.

This assay targets the RNA of a portion of the Orf1 region from the Feline Calicivirus and DNA of a portion of the glycoprotein B gene from Feline Herpesvirus-1.

Feline

To ensure inclusion in the test run, samples should arrive the day prior to test day.

Submit swabs in sterile, redtop tubes (without additives) or other sterile screwcap containers to with a small amount of saline (enough to cover the fibrous head of the swab) to maintain moisture. Viral transport media and universal transport media are also acceptable. Gel, such as culturette media or the type found in serum separator tubes, can inhibit PCR and should not be tested. Bacterial transport containers are not appropriate for PCR testing. If bacterial culture is also requested, please submit a second swab in the appropriate bacterial transport container.

Whole blood (EDTA, Heparin), (0.5 ml minimum)

Detection of Dirofilaria immitis antigen, feline leukemia virus antigen, and antibody to feline immunodeficiency virus. This test method is not affected by hemolysis or lipemia.

Feline

Submit samples on ice.

This is a NAHLN assay; approval to conduct surveillance testing is based upon satisfactory completion of the yearly proficiency test. Please contact your local/state veterinarian before submitting samples to the NDSU-VDL. Specific foreign animal disease investigation (FADI) and collection procedures must be followed before the test can be performed.

Bovine | Ovine | Caprine | Porcine | Wildlife Exotic | Other

Samples must be received 11 a.m. on the test day to ensure the reported turn around time.

Isolation and identification of fungus from diagnostic samples.

Please note that the laboratory does not culture for Blastomyces dermatididis, a dimorphic fungi. If suspected, cytology or serology may be more appropriate test methods. Please contact the laboratory to aid in choosing the best test based on case history and sample type prior to submitting your sample.
