Proper blood collection is essential for accurate laboratory results. Techniques vary depending on the animal and the volume of blood needed. Venipuncture is the most common method, utilizing appropriate needles and evacuated tubes containing anticoagulants (like EDTA for hematology) or no additives (for serum chemistry). Capillary blood collection, using a lancet to obtain a small blood sample from a superficial vessel, is sometimes used for smaller animals or when only a small volume is required. After collection, samples are carefully labeled with the patient’s information and the date and time of collection. Blood samples for serum chemistry are allowed to clot before centrifugation to separate the serum. Samples for hematology are mixed gently with the anticoagulant and then analyzed promptly or stored appropriately until analysis.

Interpretation of Common Laboratory Findings and Clinical Significance

Interpreting laboratory results requires careful consideration of the animal’s species, breed, age, and clinical presentation. For instance, a low RBC count (anemia) might indicate blood loss, destruction of red blood cells, or impaired red blood cell production. An elevated WBC count (leukocytosis) could signify infection, inflammation, or stress. Abnormal electrolyte levels can indicate dehydration, kidney disease, or endocrine disorders. Interpreting these findings in conjunction with the animal’s clinical signs helps veterinary professionals reach a diagnosis and develop an appropriate treatment plan. For example, a dog presenting with lethargy, pale gums (indicating anemia), and a low RBC count on a CBC would suggest further investigation into the cause of the anemia, potentially including blood loss or underlying disease.

Use of Laboratory Results to Guide Treatment Decisions

Laboratory results are integral to guiding treatment decisions in veterinary medicine. For example, antibiotic selection is often guided by culture and sensitivity testing, which identifies the bacteria causing an infection and determines its susceptibility to various antibiotics. Monitoring blood glucose levels in diabetic animals helps adjust insulin dosages. Assessing kidney function through BUN and creatinine levels helps determine the need for fluid therapy or dietary modifications in animals with kidney disease. In cases of suspected poisoning, specific laboratory tests can identify the toxin and guide treatment accordingly. A cat with suspected pancreatitis might have elevated lipase and amylase levels, prompting treatment with supportive care and pain management. Regular monitoring of bloodwork allows for adjustments in treatment based on the animal’s response and helps ensure optimal patient outcomes.
