Analysis of Infectious Chronic Endometritis (ALICE) is a test that detects pathogenic bacteria in the endometrium (uterine lining) so that the doctor can recommend treatment that is appropriate for the type of pathogenic bacteria found. Pathogenic bacteria cause chronic endometritis, which is associated with implantation failure and recurrent miscarriage. In cases of implantation failure or recurrent miscarriage, chronic endometritis can increase up to 66%.
