AI Overview
The RLN (Relaxin) Rapid Test is a veterinary diagnostic tool used to detect pregnancy in dogs and cats. It detects the relaxin hormone, produced by the placenta, in serum or plasma as early as 22-28 days post-breeding. These kits provide results in approximately 10–15 minutes, serving as a reliable early pregnancy screen for breeders and veterinarians.
Key Aspects of RLN Rapid Tests
- Target Species: Specifically designed for dogs (canine) and cats (feline).
- Timing: Optimal testing is around 25–30 days post-mating, as relaxin peaks between 42 and 56 days.
- Sample Type: Requires serum or plasma.
- Results: Two lines (C and T) indicate a positive result, while one line (C) indicates negative.
- Purpose: Helps confirm pregnancy or diagnose suspected pregnancy issues early.
Commonly Available Kits
- Sabervet Canine Relaxin Rapid Test: Specifically for canine pregnancy diagnosis after 28 days.
- Witnessâ„¢ Relaxin: A commonly used, rapid, and accurate test kit.
- Ringbio Canine Early Pregnancy Test: A lateral flow test with high sensitivity.
- Diagnocine Canine/Feline Test: Detects pregnancy in both cats and dogs.
How to Use (General Procedure)
- Collect Sample: Serum or plasma is collected by a veterinarian or qualified professional.
- Add Sample: The sample is placed on the test device.
- Wait: Results appear in 10-15 minutes, but it is advised not to interpret results after too long (e.g., 20 mins) to avoid false interpretations.
Interpretation
- Positive (+): Both Control (C) and Test (T) lines appear.
- Negative (-): Only the Control (C) line appears.
- Invalid: No lines appear, or only the T line appears.
Disclaimer: Rapid test kits are for initial screening; a definitive diagnosis should be confirmed by a veterinarian.
