Karyotyping is a common method of human genetic abnormalities Chromosome analysis for the purpose of the entire set of chromosomes (metaphase), such as trisomies and / or structural defects such as deletions or within individual chromosomes to detect.

Here are both CGH and FISH and / or other techniques are used to the nuances to get better. To advance through the gene level via the optical analysis systems, molecular genetic methods are used more and more, however.

The classical karyotyping has proven successful in all areas of genetics over the years, from the prenatal diagnosis on the postnatal diagnostics to tumor cytogenetics, in particular in the classification but also in the follow-up of tumor occurrence has meaning.
