There are certain genetic markers you can test for, but not all forms of autism appear in the tests we have today.

Then there's things like the folate blocking antibody (https://pmc.ncbi.nlm.nih.gov/articles/PMC4783401/) which you can do a blood test for, but again not all people with autism have the antibody.
