Karyotype Test

Chromosome Analysis

What Affects the Test

Factors that can interfere with your test or the accuracy of the results include:

• Being treated for cancer. Chromosomes may be damaged by some types of cancer treatment.
• The area where the cells are collected. The results of a karyotype test may depend on whether the cells were collected from the amniotic fluid, the fetus, or the placenta.

Your health professional will discuss with you any factors that can interfere with your test and the accuracy of the results.
