Pear (f94) IgG4 details
What Pear (f94) IgG4 shows
This test measures IgG4 antibodies to proteins in pear. Your immune system commonly makes IgG4 to foods you eat regularly, so the result mainly reflects exposure to pear rather than an allergy. Food IgG4 tests are sometimes used to look at possible food sensitivities, and a higher result generally means more frequent or recent exposure. However, the link between food IgG4 levels and symptoms is debated, and this test does not measure the IgE antibodies involved in classic food allergy. Results are best discussed with a clinician alongside your symptoms and diet, rather than used on their own to cut out foods.
