A fertility check is designed to assess reproductive health, not allergies. Allergies are immune-mediated conditions diagnosed via specific IgE, skin prick tests, or oral challenges. While some DNA tests can indicate genetic predispositions for lactose intolerance or celiac disease (strong evidence), histamine intolerance has weak support, and IgG food sensitivity tests are considered pseudoscience. A fertility test typically evaluates hormones, sperm quality, or genetic factors related to reproduction – not allergy markers. Therefore, it is not useful for allergy assessment. If you suspect allergies, consult an allergist. The evidence for using a fertility check for allergies is nonexistent or marketing-based.
