Petechiae rashes on upper chest. What could this be? I have had blood test for lupus and sjogren's syndrome but all came back negative except C3 level

Are they petechiae?: Real petechiae do not lose their color when you press down on them. With your dry eyes and joint pain, sjogren and lupus labs are in order. What's your platelet count, did you bleed badly during a dental procedure, and did your physician try something simple like a capillary fragility / tourniquet test? If it really petechiae without signs of clotting trouble, a dermatology consult is in order. ...Read more

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
