The physician has ordered chromosomal analysis for a newborn baby. Which test does the nurse realize will most likely be performed with this baby?
1. karyotype
2. newborn screen
3. carrier testing
4. preimplantation genetic diagnosis
Correct Answer: 1
The karyotype provides an analysis of the number and structure of the chromosomes. Newborn screening is performed shortly after birth. It seeks to identify inborn errors of metabolism. Carrier testing is completed on asymptomatic individuals who may be carriers of one copy of a gene alteration that can be transmitted to future children in an autosomal recessive or X-linked pattern of inheritance. Preimplantation genetic testing involves the detection of disease causing gene alterations in human embryos just after in vitro fertilization and before implantation in the uterus.
