Pets need blood work at three main times: as a baseline when healthy, before anesthesia, and when they are sick or getting older. Petfolk Veterinary & Urgent Care - Fort Mill runs much of its blood work and lab testing in Fort Mill in its own in-house laboratory, so many results are ready while you are still in the building.
Petfolk Fort Mill is a veterinary clinic in Fort Mill, South Carolina, at 1642 SC-160, Suite 104, on Highway 160 West. A single result says less than a series from the same pet over the years, because the vet can see a number drift before your pet shows any sign.

What does a pet blood panel check?
The two most common tests are a complete blood count and a chemistry panel.
Complete blood count (CBC). Counts red cells, white cells and platelets (the cells that help blood clot). Low red cells can point to anemia; high white cells can point to infection or inflammation.
Chemistry panel. Measures substances that show how organs are working, such as kidney values (BUN and creatinine), liver enzymes, blood sugar, protein and electrolytes (salts like sodium and potassium).
Other common lab tests include a urinalysis (a check of the urine for concentration, protein, sugar and signs of infection), a fecal test, and the yearly heartworm test. See heartworm testing in Fort Mill for why dogs need that test even on prevention.
When does a healthy pet need blood work?
A healthy pet needs blood work before anesthesia, such as a spay, neuter or dental cleaning, and on a regular schedule as it ages. A pre-anesthetic panel checks that the liver and kidneys can process the drugs. These first numbers become your pet's own normal: a value at the high end of the range means more when you know it sat at the low end two years earlier.
How often do sick Fort Mill pets need lab work?
Lab work is part of many sick visits at Petfolk Fort Mill. From October 2025 to October 2026:
More than 4 in 10 Fort Mill sick visits (43%) included lab work of some kind.
About 1 in 5 (20%) included blood work.
For urinary problems, 58% included blood work and half (51%) included a urine test.
Because the clinic has an in-house lab, the vet can often review a CBC and chemistry panel during the visit and start treatment with that information in hand.
Why might my dog need blood work after time near water?
Blood work helps the vet check the kidneys and liver, the organs leptospirosis often affects. The CDC notes that leptospirosis, a bacterial infection spread in the urine of infected animals, can survive in water or soil for weeks to months, and risk rises after heavy rain and flooding. Dogs that drink from puddles or splash through the streams along the Baxter Village Trail after a storm can be exposed. If your dog seems unwell after time near standing water, tell the Petfolk Fort Mill vet.
How often should older pets have blood work?
Older pets usually need blood work at least once a year, and sometimes more often, because kidney disease, thyroid changes and diabetes often start quietly. The Petfolk Fort Mill vet suggests how often based on your pet's age, health and last results, and adds a urinalysis when the kidneys or bladder need a closer look. The senior pet care page covers what else changes at an older pet's checkup.
Pets on long-term pain relievers, seizure drugs or thyroid medicine also need regular blood checks to confirm the dose is still right.
How should I prepare my pet for a blood draw?
Ask when you book whether your pet should skip breakfast, since a recent meal can affect blood sugar and fat levels. Water is usually fine.
Bring a list of every medicine and supplement your pet takes, with doses.
If your pet gets very anxious, say so when you book. The Petfolk Fort Mill team uses Gentle Handling, and the vet may suggest a calming medicine to give at home first.
Expect the draw to take a few minutes, usually from a leg vein or the neck.

Which signs mean my pet can't wait for a lab visit?
A pet that collapses, has pale gums, is struggling to breathe or is bleeding without stopping needs care before any booked lab work. Go to a 24-hour emergency hospital first.
