One Invalid Test in a Box? Don't Panic – Here's How to Get Reliable Results Every Time

While the PawsXfun kit is highly reliable, user feedback provides valuable tips for maximizing accuracy and troubleshooting rare issues.

The Testing Window is Critical:
The kit is recommended for use 18-90 days after breeding. For optimal accuracy, many sources suggest testing around day 22-28 -1-2-4. Testing too early or too late can affect reliability.

What to Do About Invalid Tests:
Kevin Brown noted: "One strip from the 5-pack never showed a control line. Used a second strip from same box on same sample — worked perfectly. Probably a manufacturing defect. The other 4 were fine." If you see an invalid test:

1. Retest immediately with a new strip from the same kit.

2. Check the sample – ensure the urine is fresh and clean.

3. Follow instructions precisely – exactly 3 drops in the sample hole.

Stability & Storage:
Each test is individually packaged for freshness. The kit remains stable at room temperature (2-30°C), avoiding the need for refrigeration. However, it's wise to keep it in a dry, cool place out of direct sunlight -12.

False Negative Risk:
Be aware of a biological limitation. In some sows, estrogen levels can fluctuate mid-pregnancy, which could lead to false negatives if testing occurs during a natural dip in hormone concentration -4-7. If a sow tests negative but you still have reason to believe she is pregnant, repeat the test a week later for confirmation.
