Each source measures something a little different: published clinic prices, national averages or real owner bills. Use them to plan, and ask your vet for a written estimate.
What it is
The vet pokes the lump with a small needle, spreads the cells on a slide, and looks at them in-house or sends them to a pathologist. [2]
When vets recommend it
Vets often recommend it for any new lump, especially one that grows or changes. [2]
Recovery and aftercare
There's no recovery time for most dogs. If results are unclear, a biopsy may be next. [2]
What affects the cost
- Who reads the slides In the clinic: $40–$75. An outside pathologist: $190–$350. [1]
- Where the sample comes from A lump the vet can feel needs only a needle. Something inside the body needs ultrasound to guide it. [1]
- How many sites Each extra site adds $75–$95 for the sample and $190–$345 for an outside reading. [1]
- Rush results Priority readings were billed higher in our data. [1]
Ways to save
- Ask if the quote includes the reading The sample and the reading are often separate lines, and the reading can cost more than the sample. [1]
- Ask who will read the slides In our data a reading in the clinic cost $40–$75 and an outside pathologist $190–$350. Your vet can tell you which is right for this lump. [1]
- If several lumps will be sampled, ask the per-site price Ask for both the sample and the reading. Outside readings add up per site. [1]
Common questions
How much does fine needle aspirate (lump test) for dogs cost?
Fine needle aspirate on owner bills, median: $160. Your vet's written estimate is what counts, since prices vary by clinic, region and your pet's needs.
How much does a fine needle aspiration cost for a dog?
In VetReceipt's data (34 real line items), individual fine needle aspirate and cytology charges run $80–$300. Most bills split the cost in two: taking the sample (about $45–$125 for a lump the vet can feel) and reading it (cytology, $40–$75 when the vet reads the slides in the clinic or $190–$350 when they go to an outside pathologist). Added together, the aspirate and the reading came to about $115–$390 on the dog invoices in VetReceipt's data, with $250 a typical total. The exam fee is usually a separate line.
Is the cytology reading charged separately from the aspirate?
Usually, yes. In VetReceipt's data, most clinics bill the needle sample and the cytology reading as two lines, and some put both in one line (one-line FNA-plus-cytology charges ran about $260–$305). That is why a quote of "$60 for the aspirate" and a quote of "$300 for an FNA" can describe the same test. Ask your veterinarian whether the price includes the reading, and whether the slides are read in the clinic or sent to a lab.
Will pet insurance pay for it?
Many accident-and-illness plans help with treatment like this if the problem isn't pre-existing and any waiting period has passed. Check your policy, and ask your vet for an itemized estimate you can send to the insurer ahead of time.
