Is there a genetic test for keloids formation?

Not that I am aware: Some people are keloid formers and others are not. Keloids are more likely to form in areas of high use as well. If you form keloids, consider a more balanced alkaline diet (you can google alkaline diet) . Acupuncture is amazing at reducing keloids! I am unaware of a genetic test. Most are expensive, usually not covered by insurance and not necessary when these other things work so well.
