Genetic testing can yield false positives, as seen in a case where a person received conflicting results for a genetic mutation related to early-onset Alzheimer's. A study showed that 40% of the variations claimed by genetic tests were inaccurate, potentially leading to panic and unnecessary stress for customers. This highlights the need for caution when interpreting genetic test results due to the high likelihood of errors and the looming regulatory scrutiny. Additionally, concerns over cyber security in handling genetic data add to the risks associated with genetic testing.
