Frequently Asked Questions - KaryoLite BoBs™ Testing

KaryoLite BoBs™ Testing

What is KaryoLite BoBs™?

KaryoLite BoBs™ is a type of a specialized test called PGS (preimplantation genetic screening) used during IVF (in vitro fertilization), designed to improve the outcome of pregnancies. On either day 3 or day 5 of the IVF process, the KaryoLite BoBs™ test can be performed to identify any aneuploidies in the newly formed embryo. The physician then selects embryos with normal test results to transfer to the mother’s uterus for implantation.

Aneuploidy is a chromosomal abnormality that occurs during early development of the embryo, caused by random errors in cell division, resulting in too many or too few chromosomes. Human cells typically contain 46 chromosomes; if the embryo has any more or any less than 46 chromosomes, it usually fails to implant or results in miscarriage.

KaryoLite BoBs™ can detect aneuploidies such as:

Down SyndromeExtra copy of chromosome 21
Edwards SyndromeExtra copy of chromosome 18
Patau SyndromeExtra copy of chromosome 13
Turner SyndromeMissing copy of X chromosome
Klinefelter SyndromeExtra copy of X chromosome
Trisomy X SyndromeExtra copy of X chromosome
XYY SyndromeExtra copy of Y chromosome

*many aneuploidies are not listed above, as they are lethal in the first trimester and can never lead to a viable baby.

The KaryoLite BoBs™ testing is particularly beneficial for:

  • Couples where the mother is 35 years or older
  • Couples who have experienced multiple miscarriages
