5Strands is a company that offers at-home intolerance tests. They use a method called bioresonance imaging to determine your actual intolerance status. However, there are doubts about the scientific validity of 5Strands intolerance tests. It's critical to keep in mind that no at-home allergy test should be a substitute for a consultation with a veterinarian. It's always a good idea to share the outcomes with a healthcare professional.
