What is the likelihood of a false negative herpes type specific blood test with background of lupus (sle)?

What is the likelihood of a false negative herpes type specific blood test with background of lupus (sle)?

About 0% to 9%: Quest diagnostics' website states that their herpes type-specific IgG antibody test is 91-100% sensitive, so there are a few false negative results. A repeat test can be done 4-6 weeks later, if worried about a false negative. Lupus should not affect the result, but if a person is on strong immuno-suppressive therapy, his antibody production may be blocked, which may make test results unreliable. ...Read more

If it really petechiae without signs of clotting trouble, a dermatology consult is in order. ...Read more
