 PGH is often used to reinforce other methods of genetic testing, and is considered more accurate than certain more common PGD methods because it has been found to reduce risk of misdiagnoses.Studies have found that misdiagnoses due to allele dropout (ADO), one of the most common causes of interpretation error, can be almost entirely eliminated through use of PGH.Further, in the case of mutation due to translocation, PGH is able to detect chromosome abnormality to its full extent by differentiating between embryos carrying balanced forms of a translocation versus those carrying the homologous normal chromosomes.
