I can't think of any medical procedure or drug that's 100% without risks. And, as far as risks go, 1 in 3000 is pretty good.

Given the benefits as a screening test, I'll take that risk. --- [0]: https://www.mayoclinic.org/diseases-conditions/stevens-johnson-syndrome/symptoms-causes/syc-20355936 https://www.mayoclinic.org/diseases-conditions/stevens-johns...
