Food sensitivities are not the same as food allergies.  In fact, the reactions to food sensitivities are often delayed by 24 hours or more after ingestion.  This makes it very difficult to identify these types of delayed immune reactions. If you have IBS, heartburn or any other gastrointestinal complaints, headaches or migraines, inability to lose weight, fatigue, insomnia, eczema or any other skin condition, anxiety, depression, arthritis, or even some types of sexual dysfunction, then this test may help you to identify a cause.
