Featured case
Swollen lymph node diagnosis.
A 14-year-old male Yorkshire terrier named Charlie presented with a firm swelling under the jaw and decreased appetite. Specimens were collected for an IDEXX CBC-Select, serum chemistry including an IDEXX SDMA Test, total T4, complete urinalysis, and Lab 4Dx Plus Test. Fine needle aspirates were collected from the prescapular, axillary, inguinal, and popliteal lymph nodes, as well as the left mandibular lymph node. Slides were prepared from the aspirates, and all specimens were submitted to IDEXX Reference Laboratories. Diagnostics revealed mild nonregenerative anemia, mild neutrophilia, monocytosis, eosinopenia, increased SDMA, ALP, amylase, and lipase levels, and decreased albumin. Charlie was diagnosed with multicentric large cell lymphoma, an aggressive form of cancer. The client declined further diagnostic testing and opted for palliative treatment with prednisone until euthanasia is chosen.

Pathology submission guidelines
Accurate and timely cytology results start with good quality slides
Best practices on how to make, prepare, and pick the best slides for submission.
Always remember to:

- Keep 1–2 unstained slides to use if the pathologist recommends additional testing.

Fine needle aspiration and nonaspiration
- Use for skin/subcutaneous masses, lymph nodes, and internal organs.
- Select the technique best suited for the tissue to avoid cell lysis or excessive blood.
- Use 22-gauge needles, which work well for most tissue types.
Blood films
- Use fresh, well-mixed anticoagulated blood to avoid specimen deterioration.
- Maintain an approximate 30° angle between the spreader and specimen slide throughout.
- Spread the specimen in one smooth, steady motion.
Line smears
- Use for body cavity effusions, bronchoalveolar lavage (BAL)/tracheal lavage, and joint fluid.
- Include a direct smear; use an additional line smear for specimens with low cellularity or suspected infectious agents. If needed, use a squash prep for flocculent material.
- Submit a buffy coat and a direct film for specimens with large blood content.
Urine sediment
- Use 5 mL of fresh, well-mixed, centrifuged urine (set centrifuge to urine/400 x g).
- Maintain an approximate 30°–40° angle between the spreader and specimen slide.
- Spread the specimen halfway down the slide; stop abruptly to create a line.
Always remember to:
- Follow the recommended stain times.
- Check slides to see if additional staining is required.
- Replace stains as needed to prevent stain precipitate.
