Equine Chorionic Gonadotropins (eCG)

Sample Requirement

Turnaround Time

Serum

Same working day

Serum gonadotrophins (eCG) may be detected in mares where functional endometrial cups are present.  For accurate results, serum samples should be collected between 45 and 95 days since the last date of mating.  False negative results are unusual inside this period, but can occur in rare cases where eCG levels are below test 'threshold'.  False positive tests are more common and may occur when early foetal death has left residual functional cups.  In such cases the mare’s serum may remain eCG positive for the functional life of the cups, sometimes up to 100 days.
