Can doxy 200x2 a day cause a false negative ana test? or a falsely normal esr test if blood was drawn two days after finishing treatment?
A doctor has provided 1 answer
It is possible that the condition being treated for with doxycycline could have caused elevated ESR, positive ANA, there are rare cases of doxycycline induced cutaneous lupus described.
