EFT = Endometrial Function Test
More information on this test is here:http://info.med.yale.edu/obgyn/kliman/infertility/dx/diagwelcome.html
Your RE would send the samples to Dr. Kilman at Yale University.
I'm currently 25 weeks pregnant with twins. This was my first cycle after doing the biopsy. We altered my progesterone protocol for this cycle based on the EFT results.
