…severe rouleaux formation. The best way to distinguish between these two phenomena (with important consequence for diagnosis and patient care) is to perform a saline dilution test, which is also called a saline dispersion test. This is done by placing one drop of blood to 4 drops or as high as 10 drops of isotonic saline (0.9% NaCl), i.e. a 1:4 or 1:10 dilution of blood to saline) and then examining the dilution as a wet mount (similar to that d…
…epinephrine while the latter could be due to antigenic stimulation, lymphoma or a chronic lymphocytic leukemia. For more information, see related links below on individual leukocyte changes and leukogram patterns (under leukogram changes). Decreased WBC counts (leukopenia) As indicated above, a WBC should never be interpreted alone, but should be interpreted with respect to the changes in the individual leukocytes that comprise the WBC count. For…
…show that postpartum NEFAs are more predictive of downstream diseases (displaced abomasum, metritis, mastitis) and decreased reproductive performance than prepartum NEFAs or postpartum BHB in dairy herds in the Northeastern USA. Sample collection Recommendations for sample collection for transition cow energy profile or “metabolic profile” testing Collection tube: A red top tube is recommended for sample collection. Serum should be…
…to many bovine diets). The rate of urea production in the liver is dependent on hepatic function and digestion and catabolism of protein, i.e. urea formation is decreased in certain liver diseases (e.g. portosystemic shunts, synthetic liver failure [not just hepatic injury]) and increased with protein catabolism or protein digestion in the intestine (upper gastrointestinal bleeding). Urea is freely filtered through the glomerulus and passively d…
…ually provided on hemograms,, mean platelet component (MPC, measure of the internal complexity of the platelet) and platelet distribution width (PDW, a measure of the variation in platelet volume). Blood smear examination: This encompasses examination of a blood smear prepared from peripheral blood and stained with a hematologic stain (e.g. Wright’s stain or a rapid stain like Diff-quik). This yields the following information: Differenti…
…gh we did not do direct comparisons between these two sample types in the same animal. Stability CRP was stable for storage at 14 days refrigerated or at room temperature. Sample could be frozen and thawed for 4 cycles (Hillström et al 2014). In an additional study with a higher sensitivity assay (this was accomplished by adding 10x more sample than normally used), CRP was stable in frozen samples stored in a dedicated freezer at -80°C…

…by plants and is present in food, and K2, which is synthesized by bacteria in the intestinal tract. Vitamin K1 and K2 are fat-soluble compounds. K1 is absorbed in the proximal small intestine and requires bile for absorption (being fat soluble) whereas K2 is absorbed in the ileum and colon. Vitamin K3 is a synthetic compound that is less lipid soluble and is absorbed in the ileum and colon. Once in the liver, vitamin K works to activate coagulat…
…heritance pattern in Beagles is autosomal with incomplete dominance. In colony-bred mongrels, the disorder is autosomal recessive. Factor VII deficiency is not usually accompanied by detectable bleeding. Affected individuals may experience bruising or prolonged bleeding following surgery, postpartum hemorrhage and hematoma formation. Usually, the condition is discovered incidentally during screening tests for blood clotting ability. It is charact…

…uced by β cells in the pancreatic islets. Insulin release is stimulated by glucose and amino acids, among other compounds, including fatty acids, glucagon, and incretins released by the gastrointestinal system, such as gastric inhibitory polypeptide and glucagon-like peptide 1. Glucose is the main stimulus, however, and works via being taken up gy GLU-2 receptors in islet cells, which then stimulates insulin release (performed and newly produced)…
Close attention must be paid to all aspects of sample collection, handling and storage, to ensure the most accurate clinical pathologic results. This section provides general guidelines and recommendations for optimally collecting and submitting blood samples for clinical pathologic testing. More detailed information on specific recommendations for individual tests can be found under related sections (hematology, hemostasis, urinalysis, chemistr…
