Top Tip for Fine Needle Aspirates: Reduce Blood Contamination

Fine needle aspirates (FNAs) are a cornerstone diagnostic tool in veterinary medicine, but one common frustration is blood contamination in the sample. This can dilute results and hinder cytological analysis.

Dr. Fred Gromalak from SVS Imaging shares a quick and effective tip to overcome this issue:

1️⃣ Attach the needle to your syringe and locate the area of interest.
2️⃣ Aspirate the lesion as usual. If blood fills the hub, stop.
3️⃣ Remove the needle and replace it with a new one.
4️⃣ Place your finger over the hub to create negative pressure.
5️⃣ Reattempt aspiration using the same technique.

This small adjustment significantly reduces blood contamination, allowing you to collect high-quality samples for more accurate diagnoses.

Master this simple trick and elevate your veterinary cytology game!
