Staining and Slide Preparation Once the cells are harvested, they are treated with a hypotonic solution to expand them, then fixed and dropped onto glass slides. Cell Culture and Preparation After collection, the sample is transported to a laboratory and placed in a controlled environment to encourage cell division.

Detailed documentation ensures that findings are accurately recorded for future reference. Understanding how is a karyotype performed helps clinicians interpret the results and determine the most appropriate management plan for patients.
Staining with specialized dyes, often Giemsa, creates a visible banding pattern unique to each chromosome. Results are communicated to the referring physician, who explains their significance in the context of the patient’s medical history and symptoms.

A karyotype arranges these chromosomes in a standardized format, allowing geneticists to identify missing, extra, or rearranged material. In prenatal cases, amniotic fluid or chorionic villi are collected via specialized procedures.
