Sample Collection Procedures for Veterinary Medicine

Sample Collection Procedures

• General Sample Collection: Collect samples from skin, ears, mouth, nasopharynx, oropharynx, stomach, small intestine, and colon.
• Tissue Biopsy: Aspirate tissues using a fine needle and a 22-259 gauge needle. Collect 3-12 ml of tissue sample and place in formalin for preservation. (Use 10x specimens.)
• Urine Collection: Collect urine samples.
• Bone Marrow Collection: Aspirate bone marrow using a Rosenthal needle. Appropriately sample the marrow.
• Vaginal Cytology: Examine cells from the vagina to determine estrus stages (parabasal, intermediate, superficial, and atypical).

Centesis Procedures

• Abdomen Wall Insertion: Insert a needle through the abdomen wall into the bladder to collect urine.
• Arthrocentesis: Collect synovial fluid from a joint (e.g., knee).
• Bronchoalveolar Lavage: Use a bronchoscope to lavage the tracheal, bronchial, and nasal cavities, which are common sites for sample collection.
• Nasal Flush: Flush and collect samples from the nasal cavity.

Enema Types

• Warm Water Enema: Administer warm water enemas, which are water-based.
• Soap Enema: Use soap for enemas.
• Mineral Oil Enema: Employ mineral oil for enemas.
• Lubricant Enemas: Utilize lubricants or tubing.
• Medication Enemas: Add medications to enemas for specific needs.

Other Information

• Specific Procedures: There is information regarding insertion techniques, materials, measurements, time estimations, and types of catheters. Equipment used include, but not limited to, red rubber (French), PVC, Foley catheters, and PTFE materials.
• Sample Preservation: Samples should be placed in proper solutions (EDTA, formalin).
• Sample Handling: Important steps regarding sample handling and procedures are noted within the text.
• Procedure Variations: Information details variations in procedures and collection methods.
• Associated Conditions: Collect samples relevant to specific disease-associated conditions like peritonitis and obstruction, and their respective procedures.
