Clinical Context
Canine relaxin measurement supports early pregnancy confirmation after implantation.
Interpretation should always combine the quantitative result with the patient's signalment, history, clinical signs, and any other laboratory findings. A single value is rarely diagnostic on its own; serial measurements often provide more useful information.
Reference Range
Reference ranges vary by species, age and laboratory method — always interpret against the kit IFU and your in-house validation.

FAQ
What does the Canine Relaxin test measure?
Migibio's Canine Relaxin test is a quantitative fluorescence immunoassay (FICT) run on the FIA680/FIA880 analyzer. It is intended as an aid in clinical assessment: Canine relaxin measurement supports early pregnancy confirmation after implantation. The exact specimen, sample handling, and reporting units are specified in the kit IFU.
When is relaxin testing most useful?
When clinical signs suggest a hormonal disorder, during breeding planning, or to monitor thyroid or adrenal function over time. Serial quantitative results are usually more informative than a single value. For dogs, use the result with the clinical history, physical examination, and any other laboratory findings.
