In-Clinic Animal Pregnancy Test

Test applicable to: Dog and Cat
Sample: Serum and Plasma
Temporarily Discontinued 

FASTest RELAXIN is a rapid immunochromatographic assay for the detection of Relaxin in the plasma or serum of dog and cat. It is based on a simple “lateral flow” technique using two unique monoclonal antibodies. It offers a simple, reliable, inexpensive means of early pregnancy detection in the dog and cat.

Qualitative Detection Of The Pregnancy Hormone Relaxin 

Because detectable levels of Relaxin are only present in the serum or plasma of pregnant bitches and queens, FASTest RELAXIN can be used as an indicator for pregnancy and for monitoring pregnancy status if there is concern about spontaneous abortion or to exclude pseudopregnancy.
