[1] [2] Karyotyping is the process by which a karyotype is discerned by determining the chromosome complement of an individual, including the number of chromosomes and any abnormalities.

Spectral karyotyping is an image of colored chromosomes. Spectral karyotyping involves FISH using multiple forms of many types of probes with the result to see each chromosome labeled through its metaphase stage. This type of karyotyping is used specifically when seeking out chromosome arrangements.
Spectral karyotyping (SKY) looks at the entire karyotype by using fluorescent labels and assigning a particular color to each chromosome. SKY is usually performed after conventional cytogenic techniques have already detected an abnormal chromosome. FISH analysis is then used to confirm the identity of the chromosome. [50]
Microfluorimetry has uses for many different fields including cell biology, microbiology, immunology, cell cycle analysis and "flow karyotyping" of cells. [2] In flow karotyping, isolated metaphase chromosomes are stained and measured in a flow microfluorometer. Fluorescent staining of chromosomes can also give distribution about the relative ...
Image: example of karyotyping showing a total of 46 chromosomes in the genome. Molecular cytogenetics combines two disciplines, molecular biology and cytogenetics, and involves the analysis of chromosome structure to help distinguish normal and cancer-causing cells. Human cytogenetics began in 1956 when it was discovered that normal human cells ...
ASI's clinical applications for laboratories include the scoring of chromosome analysis and karyotyping, fluorescent karyotyping, spectral karyotyping, karyotyping of multiple species, scanning and detection of metaphases and interphases, FISH review and analysis, matching of tissue FISH with H&E/ IHC, Brightfield whole slide imaging, IHC ...

G-banding, G banding or Giemsa banding is a technique used in cytogenetics to produce a visible karyotype by staining condensed chromosomes. It is the most common chromosome banding method. [1] It is useful for identifying genetic diseases (mainly chromosomal abnormalities) through the photographic representation of the entire chromosome ...
