Canine Relaxin Test Kits for 300P

Canine Relaxin (C-RLN) Rapid Quantitative Test

Fast, Accurate Pregnancy Detection for Dogs

The Canine Relaxin (C-RLN) Rapid Quantitative Test provides a simple, reliable way to confirm pregnancy in female dogs using plasma or serum samples. Built on fluorescence immunochromatography technology, this test delivers quantitative, lab-quality results in just 15 minutes when paired with a compatible analyzer such as the HV-MFA 300P.

By measuring relaxin, a pregnancy-specific hormone produced by the placenta, this test allows early and confident diagnosis beginning 25–30 days after breeding.

Key Features

• Species: Canine
• Sample Type: Plasma or Serum
• Sample Volume: 75 µL
• Detection Range: 0.5 – 50 ng/mLReaction Time: 15 minutes
• Storage: 4 – 30 °C, stable for 24 months
• Technology: Time-resolved fluorescence immunoassay

When to Test

Relaxin becomes detectable approximately 25–30 days post-mating.
Because hormone levels vary among dogs, a negative result may simply indicate testing too early. If pregnancy is still suspected, retest after 5 days for confirmation.

Reference Range of Relaxin in Canine Blood

Each laboratory should establish reference values representative of its own population. Results should be interpreted alongside clinical signs and other diagnostic findings.
