Veterinary Laboratory Techniques Course

Lesson 1 • Laboratory Equipment and Instrumentation

Introduces core instruments used throughout the course. Students gain confidence operating, calibrating, and maintaining essential lab tools.

Lesson 2 • Specimen Handling and Chain of Custody

Teaches proper receipt, labeling, and tracking of animal specimens. Accurate chain of custody ensures result integrity and regulatory compliance.

Lesson 3 • Laboratory Safety and Hazard Control

Covers biological, chemical, and physical hazards specific to veterinary labs. Provides the safety foundation required for all subsequent hands-on work.

Lesson 1 • Erythrocyte and Leukocyte Morphology

Trains recognition of normal and abnormal red and white blood cell morphology across species. Morphologic findings guide clinical interpretation.

Lesson 2 • Blood Collection Techniques by Species

Covers venipuncture sites and restraint methods for common domestic and exotic species. Proper collection prevents hemolysis and ensures sample quality.

Lesson 3 • Coagulation Testing Basics

Introduces prothrombin time, activated partial thromboplastin time, and fibrinogen assays. Results are interpreted in the context of bleeding disorders.

Lesson 4 • Manual Blood Smear Preparation and Staining

Teaches wedge smear technique, fixation, and Romanowsky staining methods. Quality smears are essential for accurate differential cell counts.

Lesson 1 • Endocrine and Specialty Assays

Introduces thyroid hormone, cortisol, and insulin assays using immunoassay platforms. Students understand assay sensitivity, specificity, and cross-reactivity.

Lesson 2 • Automated Chemistry Analyzer Operation

Teaches instrument setup, reagent loading, calibration, and quality control runs. Students troubleshoot common analyzer errors and flag invalid results.

Lesson 3 • Electrolytes, Glucose, and Protein Assays

Covers ion-selective electrode methods, colorimetric glucose assays, and protein quantification. These analytes are critical for metabolic and nutritional assessment.

Lesson 4 • Hepatic and Renal Function Panels

Focuses on assays measuring liver enzymes, bilirubin, BUN, and creatinine. Students correlate analyte patterns with organ dysfunction across species.

Lesson 1 • Physical and Chemical Urine Examination

Teaches color, turbidity, specific gravity, and reagent strip interpretation. Chemical screening results guide sediment examination priorities.

Lesson 2 • Urine Protein-to-Creatinine Ratio

Covers quantitative protein measurement and UPC ratio calculation for renal proteinuria staging. Results are interpreted alongside sediment and blood pressure data.

Lesson 3 • Urine Collection and Preservation

Covers cystocentesis, catheterization, and free-catch collection methods by species. Collection method directly affects sediment and culture result validity.

Lesson 1 • Antimicrobial Susceptibility Testing

Teaches disk diffusion and broth microdilution methods for determining MIC and susceptibility categories. Results guide rational antimicrobial selection in clinical cases.

Lesson 2 • Aseptic Technique and Media Preparation

Establishes sterile working practices and teaches preparation of common culture media. Aseptic technique prevents contamination that invalidates culture results.

Lesson 3 • Gram Stain and Preliminary Identification

Teaches Gram stain procedure and interpretation for rapid preliminary organism classification. Gram stain results direct media selection and treatment decisions.

Lesson 4 • Biochemical and Rapid Identification Methods

Covers catalase, oxidase, coagulase, and commercial identification panel use. Students confirm organism identity before susceptibility testing.

Lesson 5 • Specimen Inoculation and Incubation

Covers streak plate technique, selective media selection, and incubation conditions. Correct media and atmosphere choices maximize pathogen recovery.

Lesson 1 • Fecal Egg Count and Larval Culture

Teaches quantitative McMaster egg counting and larval development culture for speciation. Egg counts guide anthelmintic treatment and resistance monitoring.

Lesson 2 • Fecal Examination Techniques

Covers direct smear, flotation, and sedimentation methods for detecting gastrointestinal parasites. Method selection depends on parasite density and morphology.

Lesson 3 • Blood Parasite Detection

Covers thick and thin blood smear examination and concentration techniques for hemoparasites. Students identify Babesia, Anaplasma, and microfilaria morphologically.

Lesson 4 • Protozoan Detection and Identification

Covers detection of Giardia, Cryptosporidium, Tritrichomonas, and coccidia using microscopy and antigen tests. Protozoan identification requires specific staining and concentration methods.

Lesson 1 • Histology Processing and Sectioning

Teaches tissue processing, paraffin embedding, microtome sectioning, and H&E staining. Students produce sections of consistent thickness suitable for pathologist review.

Lesson 2 • Histopathology Tissue Fixation and Submission

Covers formalin fixation ratios, tissue trimming, and proper submission packaging. Correct fixation is mandatory for valid histopathologic diagnosis.

Lesson 3 • Systematic Cytologic Interpretation

Introduces a structured approach to evaluating cellularity, background, and cell populations. Students classify samples as inflammatory, hyperplastic, or neoplastic.

Lesson 4 • Cytology Sample Collection Methods

Covers fine-needle aspiration, impression smear, and swab techniques for various tissue types. Collection method determines cellular yield and diagnostic adequacy.

Lesson 1 • PCR Quality Control and Contamination Prevention

Establishes controls, workspace segregation, and decontamination practices essential for reliable PCR results. Contamination is the leading cause of false-positive PCR findings.

Lesson 2 • Nucleic Acid Extraction Principles

Covers DNA and RNA extraction from blood, tissue, swabs, and feces using column and magnetic bead methods. Extraction quality directly determines PCR sensitivity.

Lesson 3 • Conventional and Real-Time PCR

Teaches PCR master mix preparation, thermocycler programming, and gel electrophoresis for conventional PCR. Real-time PCR adds quantification and reduced contamination risk.

Lesson 4 • Sequencing and Advanced Molecular Methods

Introduces Sanger sequencing, next-generation sequencing concepts, and MALDI-TOF for molecular identification. Students understand when advanced methods add diagnostic value.
