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 example, the Identigene at-home test costs $149 and Genetic Profiles Corporation offers tests for $500 for a standard case and $730 for a case in which the biological mother's DNA is not available.
