Four prices decide most feline bloodwork bills: USD 80–180 for a baseline CBC with chemistry, USD 120–220 once total T4 is added, USD 40–80 for SDMA on its own, and USD 60–120 for a pre-surgical clotting screen. Converted, that is roughly GBP 60–140, GBP 95–170, GBP 30–65 and GBP 45–95, or CNY 580–1,300, CNY 870–1,600, CNY 290–580 and CNY 430–870. The panel itself is seldom the line that hurts. Repeats, add-ons ordered one at a time, and after-hours premiums are.
Buy the baseline once a year for a healthy adult cat, twice a year from age 7, and every 3–6 months for a cat already staged with kidney disease. Anything beyond that should answer a specific question asked that morning.
What sits inside a baseline panel
A CBC reports red cell count, haematocrit, haemoglobin, the white cell differential and platelets — 10–15 numbers describing infection, anaemia, hydration and clotting risk. A 12–18 value chemistry panel covers BUN, creatinine, ALT, ALP, glucose, total protein, albumin, calcium, phosphorus and the four electrolytes.
That combination catches the four conditions older cats hide well: chronic kidney disease, hyperthyroidism, diabetes and early liver change. A cat can carry all four with a normal appetite, which is why a USD 80–180 panel is the cheapest diagnostic tool in the building.
Why the same panel costs USD 80 in one clinic and USD 180 in another
Three variables move the number. In-house analysers return results in 15–30 minutes and cost the practice more per test, so the invoice runs 20–40% above a send-out. Reference laboratories answer in 12–24 hours for USD 60–110 but impose a courier cut-off, usually 4–6 p.m. Emergency hospitals bill USD 140–260 for the identical list because someone is awake at 3 a.m. to run it.
Geography is the fourth variable. A suburban US practice sits near USD 95; a London practice charges GBP 80–140; a tier-one Chinese hospital asks CNY 400–900 for a CBC plus a shorter chemistry set of 8–12 values.
Total T4: the USD 40 you should not skip after age 8
T4 as a standalone add-on is USD 40–60, which is how a thyroid panel total lands at USD 120–220. From age 8 it belongs in the annual panel, and any cat that drops 10% of body weight with a normal or better appetite needs it at the next visit rather than the next year.
Common veterinary estimates put hyperthyroidism at 1 in 10 cats older than 10 years, and the disease masks kidney disease: treating the thyroid lowers filtration rate and unmasks renal values 2–4 weeks later. That is why the pair is ordered together instead of sequentially.
SDMA at USD 40–80: buy it for kidneys, once a year
SDMA rises after roughly 40% of kidney function is lost, against 66–75% for creatinine. It is a single add-on at USD 40–80, and repeating it more often than every 6 months adds little. Its value is timing: a cat with creatinine at 1.6 mg/dL and a rising SDMA gets a diet change 6–18 months earlier than creatinine alone would allow.
One caveat worth the sentence: SDMA drifts with dehydration and with muscle mass in either direction, so a single abnormal value is repeated in 2–4 weeks before anyone stages the cat.
Pre-op clotting screen at USD 60–120
PT, APTT and a platelet count are 3 numbers that decide whether a surgeon can cut. Most practices want them within 30 days of anaesthesia, and within 7 days for a cat on any anticoagulant. It is not routine for a healthy 2-year-old neuter; it is close to mandatory for a cat whose liver values run 2–3 times normal, a breed with a known coagulopathy, or any cat that bled for more than 10 minutes after a previous venepuncture.
Price table by region
| Panel | United States (USD) | United Kingdom (GBP) | China, tier-one (CNY) |
|---|---|---|---|
| CBC plus chemistry, 12–18 values | 80–180 | 60–140 | 580–1,300 |
| Same panel with total T4 | 120–220 | 95–170 | 870–1,600 |
| SDMA add-on | 40–80 | 30–65 | 290–580 |
| Pre-op PT and APTT | 60–120 | 45–95 | 430–870 |
| Urine culture, 48–72 hour result | 80–150 | 60–120 | 400–900 |
These are ranges, not quotes. The same clinic can sit at either end on the same day depending on whether the sample goes out or stays in house.
Repeat intervals that save money
- Kitten under 6 months: one panel before the first anaesthetic, no repeat unless the kitten is sick.
- Adult 1–6 years: one baseline a year, T4 only when symptoms appear.
- Senior 7–10 years: baseline plus T4 every 12 months, SDMA yearly.
- Senior over 10 years: the same set every 6–12 months, plus blood pressure at each visit.
- Known CKD stage 2–3: chemistry, SDMA and phosphorus every 3–6 months.
- Diabetic on insulin: chemistry every 3–4 months, fructosamine at USD 30–55 when a curve looks wrong.
Five ways the bill climbs past USD 300
- Sequential ordering: paying a second USD 80–180 visit to get results one panel would have produced.
- Repeat draws 48 hours apart instead of waiting out the 2–4 week recheck window.
- Add-ons discovered late — FeLV and FIV at USD 40–80, blood pressure at USD 25–45, urine culture at USD 80–150.
- After-hours draws, which add 40–100% to the same test list.
- Anaesthesia without a pre-op screen, then a cancelled surgery, then a second pre-op.
Before approving anything, ask three questions: which values would change the plan, what the send-out versus in-house difference is, and when the next repeat is due. The reference range table tells you what an abnormal number means before the call-back. Cats over 10 need the shorter interval in our senior bloodwork protocol, and the yearly cost tool puts panels next to food, litter and insurance so the annual total is visible.
Medical decisions belong to the veterinarian looking at the cat. A panel value alone is not a diagnosis, and a cat that stops eating for 24 hours, hides, breathes fast or cannot urinate needs an examination today, not a cheaper test next week.

Frequently asked
Can I skip the chemistry panel and do only a CBC?
A CBC alone shows anaemia, infection and platelet numbers but nothing about kidney, liver or thyroid function, so it will not screen an older cat. If cost is the constraint, ask for a smaller chemistry set of 8 to 12 values rather than dropping chemistry entirely; the combined price is usually USD 60 to 130 instead of USD 80 to 180.
Why does my vet want a repeat panel two weeks later?
Single values drift with dehydration, stress and muscle mass, and one abnormal number rarely justifies a diet change or a drug. A recheck at 2 to 4 weeks on a stable cat separates a real trend from a bad afternoon, and it is cheaper than starting treatment on the wrong diagnosis.
Is SDMA worth USD 40 to 80 every year?
For cats over 7, yes. SDMA moves after about 40 percent of kidney function is gone, while creatinine waits for 66 to 75 percent. One yearly add-on at USD 40 to 80 buys earlier diet changes, but repeating it every few weeks adds cost without adding information.
