|
|
Insulin Baseline
|
INSE |
|
|
ACTH Post TRH
|
ACTHPOSTTRH1 |

ACTHPRETRH |
|
|
Equine Infectious Anemia (EIA) Virus c-ELISA |
EIAEL |
- 1ml serum. |
|
Fecal Floatation |
FLOAT |
- Fresh feces. |
|
Hemogram, Large Animal |
LA CBC |
- (2) unstained, unfixed, air-dried blood smears |
|
Large Animal Chemistry
|
LA P |
- Heparinized plasma (separated from a green top tube). - Serum (separated). |
|
Peritoneal Fluid Cytology
|
PTFE |
- 1ml peritoneal fluid in EDTA (lavender top tube); red top tube if culture anticipated plus 2-3 unstained smears. |
|
Sand Recovery Analysis |
SAND |
- Feces (8-10 fecal balls). |
|
Selenium, whole blood. |
SEL |
- EDTA whole blood (lavender top tube). - Heparin whole blood (green top tube). |
|
Serum Amyloid A |
SAA VET |
- 1ml serum or plasma. |
|
Thyroid , Equine |
THYPALLI |
- 2ml serum or plasma. |
|
Vitamin E in serum |
NDIK |
- 2ml serum. |
|
Lawsonia intracellularis qPCR |
LAWPCR |
- Feces, ileum, or tonsillar tissue. |
- Horses with EPM may present with asymmetrical muscle wasting or weakness – diagnostics to consider include Sarcocystis neurona EPM SAG 2,3,4 ELISA and Neospora hughesi ELISA. Both assays are referred to Equine Diagnostic Solutions.
- Cyathostomiasis (encysted small strongyle larval infection) may cause chronic ill thrift. In these cases the absence of strongyle eggs and larvae on fecal floatation does not rule out a diagnosis of cyathostomiasis.
- Lawsonia intracellularis, the causative agent of Equine Proliferative Enteropathy, effects horses in the weanling to yearling age range, from approximately 2 to 18 months of age. Rarely adult horses may be affected.
