Canine Pregnancy@Relaxin Rapid Test (Relaxin)

Catalog No.: JCA026D

¤  INTENDED USE

Relaxin is a specific hormone generated mainly by the placenta. It is usually used as an indicator of pregnancy status in female dogs. In pregnant dogs, relaxin can be detected from 15 days after the nidation of fertilized egg in the uterus wall. The Canine Pregnancy@Relaxin Rapid Test is a rapid test to detect relaxin in bitches that may be pregnant. The suggested detection period is 20-30 days after mating. Too early detection may lead to a negative result when relaxin in serum is too low. It is suggested to repeat the test after 1 week if a negative result was observed.

Assay Time: 5-10 minutes

Specimen: Serum, or plasma.

- Positive (+): The presence of both “C” line and zone “T” line. T line at G3 is considered as standard positive. T line < G3, is weak positive and indicates low CDV or CDV antibody level. T line around G4-G5, is strong positive. T line > G6, is very strong positive, indicates a contact with virus recently or in infection.

- Negative (-): Clear C line appears. No T line, or T line is weaker than G1. It indicates very low CDV or CDV titer. Failed immunization may happen.   

- Invalid: No colored line appears in C zone.
