Wondfo Canine Progesterone Test Strips (FIA, 10-Count)
Wondfo Canine Progesterone Test Strips (FIA, 10-Count)
Every time you pay $60–$80 for a progesterone test at the vet, you're paying for overhead — the clinic's equipment, the technician's time, the scheduling delay. When you own the Wondfo FIA analyzer and test in-house, each test costs you around $12. For a program running 3–5 females per year with multiple tests per heat cycle, that's hundreds of dollars back in your pocket every season — and you get results in 10 minutes instead of waiting for a callback.
What These Cassettes Test
These are quantitative canine progesterone test cassettes compatible with the Finecare Vet FIA (Fluorescence Immunoassay) analyzer. They measure serum progesterone in ng/mL from a small blood sample, giving you the precise number you need to identify the LH surge, confirm ovulation, and build your breeding window — not a vague "yes/no" but an actual value you can act on.
Progesterone Reference Ranges — What the Numbers Mean
| Progesterone Level | Stage | Action |
|---|---|---|
| < 1.0 ng/mL | Anestrus or early proestrus | Not in heat or too early — retest in 3–4 days |
| 1.0–2.0 ng/mL | Proestrus / approaching LH surge | Getting close — retest in 2 days |
| 2.0–5.0 ng/mL | LH surge window | Test daily — ovulation is imminent |
| 5.0–10.0 ng/mL | Ovulation occurring | Breed now or within 24–48 hours for vaginal AI or natural tie |
| 10.0–25.0+ ng/mL | Post-ovulation / eggs maturing | Optimal window for TCI or frozen semen (eggs fully mature at 48–72 hrs post-ovulation) |
| 25.0+ ng/mL | Luteal phase (post-breeding) | Window closing — confirm pregnancy at Day 25–28 via ultrasound |
Note: These ranges are guidelines. Always evaluate progesterone in context with cytology and the individual female's history.
Cost Per Test Breakdown
10 cassettes at $119.99 = $12 per test vs. $60–$150 at a reproductive vet clinic. If you run 3 tests per heat cycle across 3 females per year, that's 9 tests — saving you $400–$1,200 per year compared to clinic testing.
What You Need to Run These Tests
- Finecare Vet FIA Analyzer — the machine that reads the cassette (sold separately)
- Digital Micro Centrifuge — to spin whole blood into serum before testing
- Adjustable Micropipette + Tips — for accurate sample transfer to the cassette
- Lithium Heparin Blood Collection Tubes — proper anticoagulant for progesterone samples
- Blood Draw Kit — needles, syringes, and supplies for the draw

Frequently Asked Questions
Which analyzer are these compatible with?
These cassettes are designed for the Finecare Vet FIA analyzer (also sold as the Wondfo FIA Vet). Do not use with other analyzer brands — cassette-to-reader compatibility is specific to the fluorescence immunoassay platform.
Do I need to spin the blood before testing?
Yes. These cassettes use serum, not whole blood. You draw blood into a lithium heparin tube, centrifuge it to separate serum from red cells, then pipette the serum onto the cassette.
How long does a test take?
Sample prep takes 5–10 minutes. The cassette incubates in the reader for approximately 10 minutes. Total time from needle to result: 15–20 minutes.
How should I store the cassettes?
Store at 2–30°C (room temperature is fine). Keep away from direct sunlight and humidity. Do not freeze. Each cassette is individually sealed — open only immediately before use.
Can I use these for other species?
These are validated for canine progesterone testing specifically. Do not use for feline or other species.
