Animal Diagnostic Laboratory Testing

Laboratory technician pipettingThe In-Vivo Animal Core (IVAC), part of the Unit for Laboratory Animal Medicine (ULAM), offers a wide variety of laboratory tests through its Animal Diagnostic Laboratory (ADL). Experienced IVAC veterinary pathologists are also available to view results upon request. 

Blood collection must be in compliance with a current animal use protocol from U-M or your institution.

Tests are available in the following areas:

Download the IVAC-ADL Clinical Pathology Sample Guidelines before submitting your samples.

Urinalysis

Test Parameters
Color, Clarity, Specific gravity by refractometer, pH, Protein, Glucose, Ketones, Urobiligen, Bilirubin, Blood, #RBC per HPF, #WBC per HPF

Sample Collection
Ideally, urine is collected by a sterile method into a sterile container. Non-sterile samples cannot be submitted for microbiology.

Storage
Urine should be examined as soon as possible after collection, because artifacts will occur in the urine over time (cells lyse, crystals form in vitro). If a delay is anticipated before analysis, the urine should be refrigerated. Refrigerated urine should always be brought to room temperature before testing. If analysis cannot be performed promptly (< 30 minutes), refrigeration will slow microbial growth and tends to stabilize most urine components for up to 12 hours (rewarm to room temperature before analysis).

Volume
1mL urine minimum

Test Performed
In House

Test Parameters
Routine analysis, casts per LPF, bacteria, mucous, epithelial cells, crystals
