Abnormalities in your chromosomes help healthcare providers diagnose many health conditions.

How do you test for chromosomal abnormalities in adults?
A karyotype test examines blood or body fluids for abnormal chromosomes. Adults, children or babies still in the womb may need this test if they’re at risk for certain genetic conditions. Before choosing to have a karyotype test, talk with your healthcare provider about genetic counseling.
How much does a chromosome analysis cost?
The cost of genetic testing can range from under $100 to more than $2,000, depending on the nature and complexity of the test. The cost increases if more than one test is necessary or if multiple family members must be tested to obtain a meaningful result. For newborn screening, costs vary by state.

Does 23andMe test karyotype?
The technology 23andMe uses looks for specific typos (variants) in the gene instructions (called SNPs or Single Nucleotide Polymorphisms). This approach to testing, called genotyping, is not designed to identify all potential variants.
