Yes. No herbs or medicine like prazi or albendazole now. I'm following the test instructions. For the Meridian Valley Labs test it said to go a few days without digestive enzymes and anti fungals so I followed that and sent in the test today- started four days after prazi for three day test. For biohealth labs I'm following their instructions which say to wait two weeks after last antibiotic. So hoping to start that next Wednesday.
