The laboratory test mentioned is the measurement of Candida albicans IgE level. IgE refers to immunoglobulin E, which is an antibody produced by the immune system in response to an allergen.
This test is performed to determine the level of IgE antibodies specific to Candida albicans, a type of yeast that can cause infections in humans. Elevated levels of Candida albicans IgE may indicate an allergic reaction or hypersensitivity to this yeast. It can be helpful in diagnosing and monitoring conditions such as allergic bronchopulmonary aspergillosis (ABPA), a lung disease caused by an allergic reaction to fungi including Candida albicans.
Additionally, this test can be used to assess the effectiveness of treatment for Candida albicans infections or to identify individuals who may be at a higher risk of developing allergic reactions to this yeast.
