What it is:
This is a combined blood test that looks at both how hard the heart is working and whether there is any injury to the heart muscle.
Why it is beneficial to breeders:
Provides a more complete picture of heart health in one test
Helps identify hidden or early heart problems
Useful for screening breeding animals and high-value dogs
Supports faster, more confident veterinary decisions
Reduces the need for multiple separate tests
When breeders should use it:
As part of routine health screening for breeding animals
Before breeding or placing high-value dogs
When a dog has coughing, exercise intolerance, or abnormal heart sounds
When heart disease is suspected and clearer answers are needed
 
To summarize:
NT-proBNP + cTnI: A combined heart test that evaluates both heart strain and heart muscle damage for a more complete cardiac assessment.
