Alum is a chemical commonly used in homes to purify water, as a food additive, and in antiperspirants. It is impossible to conduct a paternity test (DNA test) using alum and water.

Paternity testing requires DNA analysis technology, which requires the use of specialized equipment and techniques to compare genes. DNA cannot be extracted and analyzed using chemicals such as water or alum. Paternity testing is usually performed by

1. collection of DNA samples

The following samples are used in the paternity test

Cells are collected by rubbing the mucosa of the oral cavity (inside the cheek) with a cotton swab.
Blood sample.
Rooted hair.
Other cell samples such as nails and skin fragments.

These samples are then sent to a specialized DNA identification laboratory for analysis of the genetic information.

2. Process of DNA analysis

DNA is extracted from the sample and analyzed for specific genes to compare the DNA of the parent and child. In particular, we confirm the parent-child relationship by examining the pattern of genes passed down from parent to child. The analysis requires specialized equipment and techniques, and cannot be performed with alum or other substances available in the home.

3. Conclusion

It is impossible to conduct a paternity test (DNA test) using water or alum. If you wish to confirm the exact parent-child relationship, you must request a specialized DNA testing organization.
