Yes, antiparasitics can possbily decrease the microbial burden and, therefore, the immune system's response to the parasite. The most conservative approach to Tickborne and Co-Infections testing is to discontinue all "kill protocols" (whether for parasites, microbes, yeast etc.) for 14 days prior to collecting a blood sample.
Can taking antiparasitic medications impact Vibrant's Tickborne and Co-Infections results?
