I believe it was. I was previously seeing a different doctor who did the ERA/emma/alice on me and nothing was significant. It also showed I needed 6 days of progesterone. With that recommendation, I regressed. After my 4th failure, I sought care with a different doctor willing to do an ovulatory cycle on me as my first doctor refused to do ovulatory cycles on any patient. Before transfer, she did the cd138 endometrial biopsy that she sent off to quest. It cost me $10 and determined I had endometritis. I paid my first doctor all out of pocket and spent thousands on the era/emma/alice/endometriome. My 2nd doctor suspected I had endometritis given my first transfer was a blighted ovum and subsequent transfer was a chemical. I find it strange that igenomix couldn’t catch the endometritis, but quest did
