If I've be strictly avoiding the sun due of burns, can they still run accurate inflammation test for Lupus?

Or will I have to expose myself to the rough big yellow orb in the sky :) I own Systemic Lupus, and have never be asked to expose myself to the sun before conducting tests. You are correct to avoid unnecessary exposure, and I would seriously question any medical procedure that requires you to do so. It sounds approaching your doing exactly what's necessary to protect yourself.
Take protection!!
