The Witness Relaxin is a Rapid Immuno-Migration (RIM) test intended to determine pregnancy in canine and feline patients, as well as to distinguish between pseudo pregnancy and gestation. The RIM kit measures relaxin produced by the developing placenta(s) in plasma and serum samples. Whole blood cannot be used. The presence of significant amounts of this hormone is a reliable indicator of pregnancy. Relaxin can be detected in biological samples as early as 20 days after the luteinizing hormone (LH) surge has occurred. The percentage of pregnancies detected increases later in gestation as more relaxin is produced.
