FAQs

POC results are typically available 6 days after Juno receives the maternal blood and POC samples (although up to 10 days may be required).

In some cases, embryos contain a mixture of cells, some having the correct number of chromosomes and others having an abnormal chromosome number. Such embryos are said to be ‘mosaic’. Some studies have suggested that mosaic embryos are less likely to produce a healthy pregnancy than those that have only normal cells in their biopsy specimen. However, other studies have provided contradictory information. The PGT[A]seq method used by Juno Genetics reveals when an embryo sample contains a mixture normal and abnormal cells. Any mosaic embryos detected during PGT-A will be indicated in the report issued by Juno. The choice of whether or not mosaic embryos are transferred to the uterus depends on the policy of the IVF clinic as well as national guidelines. It is recommended that transfer is considered only after consultation with a qualified healthcare professional.

If the proportion of samples that fail to give a PGT result is consistently higher than expected, this is almost always due to a problem with technique used for the cell washing and loading or, less commonly, with the embryo biopsy method. Scientists at Juno Genetics have decades of experience working with clinics in order to achieve optimal PGT results and can assist with troubleshooting. Problems are almost always solved after simple and easy to implement changes to procedure.

Many of the advanced PGT methods used by Juno Genetics are available nowhere else in the world. Consequently, it is necessary to send samples to the Juno laboratory (in Oxford, UK) in order to access the tests. In most cases, the time required for the shipping of samples, and for the complex laboratory procedures, means that embryos must be cryopreserved (vitrified) while the test is carried out. Embryos can usually be thawed and transferred during the following cycle.
