An method of performing a biopsy is provided. The method may include performing a biopsy procedure on one or more recovered blastocysts to remove one or more of trophectoderm cells or inner cell mass from the recovered blastocysts. The blastocysts are recovered via a method comprising placing a uterine lavage device having a fluid supply catheter configured to be placed trans-vaginally into a cervical canal of a human, the fluid supply catheter further configured to deliver fluid through the device to the uterus and aspirate fluid and entrain one or more blastocysts from the uterus to recover one or more blastocysts. The one or more of the biopsied trophectoderm cells or inner cell mass recovered from the one or more recovered blastocysts may be stored in a container comprising an electronic or other coding label including the biopsied cells and blastocyst identification information, and at least one molecular diagnostic assay test is performed on one or more of the biopsied trophectoderm cells or inner cell mass.
