It's not possible to do a secret DNA test without the knowledge of the person whose DNA is being tested.
Here's why:
- Legal and Ethical Considerations: DNA testing companies typically require consent from the individual being tested.
- Sample Collection: Obtaining a DNA sample without someone's knowledge is difficult and often unethical.
- Privacy Concerns: It's important to respect people's privacy and obtain their consent before testing their DNA.
If you're considering a DNA test, it's best to be upfront with the person involved and discuss the implications of the test.
