Sulfated Estrone Colloidal Gold Test Kit for Swine Early Pregnancy
🔬 Key Features
Early Detection: Identify pregnancy status from 19 days post-breeding using urine.
Simple & Fast: One-step procedure delivers clear results in 10-20 minutes.
Targeted Accuracy: Employs a competitive immunoassay specific to the pregnancy marker sulfated estrone.
Clear Visual Readout: Result determined by comparing Test (T) and Control (C) line colors.
📊 The Value of Early Pregnancy Testing
In swine production, promptly identifying non-pregnant sows is essential for optimizing fertility rates and operational economics. Delays can result in prolonged non-productive days, increased feed costs, and disrupted farrowing schedules.
Benefits for Your Operation:
✅ Enhance Reproductive Efficiency: Enable timely re-breeding or culling decisions to maintain tight farrowing intervals.
✅ Reduce Unnecessary Costs: Eliminate feed and care expenses for sows that are not pregnant.
✅ Improve Herd Management: Gain valuable early data to inform grouping, facility planning, and health protocols.
✅ Streamline Sampling: Non-invasive urine collection is simple and minimizes animal stress.
🧪 How It Works: The Science Behind the Test
This rapid test is based on competitive inhibition immunochromatography. The test strip contains antibodies specific to sulfated estrone. During the test, this hormone in the urine sample competes with a gold-labeled version for binding sites. A high hormone level (indicating pregnancy) reduces color at the Test line (T), while a low level allows the T line to develop color.
📦 Product Specifications
Use: For sows after breeding
Earliest Testing: 19 days post-breeding
Sample: Urine (first morning sample recommended)
Time to Result: 10-20 minutes
Packaging: Individually sealed test devices
Storage: Stable for 24 months at 2-30°C in a dry, dark place
🧾 Simple Testing Steps
Prepare: Allow the test device and urine sample to reach room temperature.
Apply Sample: Add 6 drops of urine to the sample well (S).
Wait: Let the test sit horizontally for 10-20 minutes.
Read: Interpret the final result by comparing the T and C lines.
📌 Reading Your Results
| Test Line (T) | Control Line (C) | Result |
|---|---|---|
| No color or lighter than C | Visible | Pregnant |
| Darker than C | Visible | Not Pregnant |
| Any result | Not visible | Invalid |
Crucial Note: A visible C line confirms test validity. This is a competitive assay: a faint or absent T line indicates a POSITIVE (pregnant) result.
⚠️ Important Guidelines
Intended Use: A screening tool for swine pregnancy only. Not for disease diagnosis.
Sample Integrity: For best accuracy, use fresh, clear morning urine.
Optimal Conditions: Perform the test at room temperature (15-25°C), away from direct sunlight.
Professional Judgment: Use results alongside clinical observation. Confirm uncertain outcomes with a veterinarian.
