I am NOT an expert, so do not wish to edit the actual article.
This statement is almost certainly incorrect "Non-artificial chimerism is so rare that there have only been 100 confirmed cases in humans.[citation needed]"
Various levels of human chimera have been found.
1) Human mothers get stem cells from their children

2) Twins exchange cells

3) Children gets cells from their mothers
https://www.nature.com/articles/s41467-021-24719-z
4) Children even get cells from their grandmothers.

The conclusion is that almost every human is a chimera at least at a very low level.
Also this statement is probably not correct. "By simply undergoing a DNA test, which usually consists of either a swift cheek swab or a blood test, the discovery of the once unknown second genome is made, therefore identifying that individual as a chimera."
If the chimeric cells involve the blood or immune system, perhaps. But that's a tiny fraction of your body cells. For example, see what level of testing was needed in this case.

Cheek, blood, hair all didn't show any sign of her chimerism. Only a sample from the cervex did. WetEV ( talk) 22:32, 5 August 2023 (UTC)

Support the April proposal to merge the new article, Human Chimerism, to here. Heavy overlap in scope, best merged to the existing article. Klbrain ( talk) 10:26, 16 June 2024 (UTC)
Support but count me out for actually implementing the merge as I don't have the required expertise to do so. Pichpich ( talk) 23:35, 24 June 2024 (UTC)
