Code Test Description * Indicates send out test   T670 Lymg IgG   Specimen 1 ml serum   Method IFA   Schedule 1–2 working days   Indication Possible exposure to Borrelia burgdorferi.   Interpretive   Guidelines A titer equal to or greater than 1:64 suggests infection or vaccination.   Comments A Lyme Western Blot is necessary to distinguish between natural exposure and vaccination.   * S16836 Lyme Western Blot (Canine only)   Specimen 1 ml serum or CSF   Method Western Blot   Schedule 1–4 working days   Indication This test will distinguish between infection and vaccination.   T170 Magnesium   Specimen 1 ml serum or heparinized plasma   Method Xylidyl Blue   Schedule Daily   Indication Mineral analysis, hypoparathyroidism, neuromuscualr disease or cardiac disease.   Interpretive   Guidelines Hypomagnesemia may be due to prolonged anorexia, vomiting, diarrhea, renal failure, diabetic ketoacidosis, sepsis or blood transfusion.   * S16535 Masticatory Muscle Myositis (2M antibody)   Specimen 1 ml serum   Method Histochemical   Schedule 7–14 working days   Indication To diagnose masticatory muscle myositis by detecting autoantibodies specifically directed against masticatory muscle proteins.   Interpretive   Guidelines A positive test result is supportive of masticatory muscle myositis but a negative test result does not exclude the diagnosis.   Comments This test dies not detect polymyositis.   * S16540 Metaldehyde   Specimen 50 g stomach contents or bait   Method GC/MS   Schedule 7–10 working days   Indication Exposure to or ingestion of slug bait.   Interpretive   Guidelines Positive results indicate recent ingestion.   Comments Ship with an ice pack.   T390 Microfilaria Knotts   Specimen 1 LT   Method Knotts   Schedule Daily   T380 Mycoplasma (Hemobartonella)   Specimen 1 LT or smear (preferred)   Method Microscopic evaluation   Schedule Daily   Indication Evaluation for the presence of this hemoparasite as a potential cause of anemia.   Comments The parasite is cyclical and transient, therefore a negative observation does not rule out the presence of mycoplasma. The presence of this parasite is often associated with immunodeficiency (e.g., FeLV infection). The longer the sample sits in LT, the fewer parasites are seen on the RBC. Heparinized samples are not acceptable for this test. Please send comments to the webmaster. ©1997-2008 Antech Diagnostics, Inc. Site design and maintenance by amesDesign.
