How do Veterinarians Test for Parasites?
Pets are typically tested for parasites through a combination of physical examinations, laboratory tests, and diagnostic procedures. The specific tests can vary based on the type of parasite being screened for and the pet’s medical history. Here’s an overview of common methods for parasite testing:
Fecal Analysis
A microscopic examination of a pet’s stool to detect the presence of intestinal parasites.
Blood Tests
Blood samples are analyzed to identify heartworm and other bloodborne parasites.
Skin Scraping
A small skin sample is examined under a microscope to diagnose mites, as well as other non-parasitic infections.
Visual Inspection
Veterinarians visually inspect a pet’s fur and skin for external parasites like fleas and ticks.
Heartworm Antigen Test
A blood test that detects antigens produced by the adult female heartworm.
Urinalysis
Urine examination for indirect evidence of parasites, such as protein loss in the urine.
PCR Tests
Polymerase chain reaction tests identify DNA or RNA of specific parasites, offering high accuracy.
X-ray or Ultrasound
Imaging techniques help visualize internal organs for signs of parasites.
Serologic Tests
Blood tests detect antibodies to specific parasites, aiding in diagnosis.
Cytological testing
A sample of fluid and/or tissue from a suspect region of parasite infection can be analyzed for signs of parasites by the type of white blood cells present.
Tape Test
A piece of tape is applied to the pet’s anal area to collect pinworm eggs for examination.
Culture Tests
Growing parasites from a sample to identify certain types like tritrichomonas.
