Acne occurs when the pores on your skin become blocked with oil, dead skin, or bacteria. Each pore on your skin is the opening to a follicle. The follicle is made up of a hair and a sebaceous (oil) gland. The oil gland releases sebum (oil), which travels up the hair, out of the pore, and onto your skin. The sebum keeps your skin lubricated and soft. Acne can be caused by one or more problems in this lubrication process.
In between exposures, a person's IgE level may drop. Sometimes an individual has a condition that affects the immune system and will not produce normal amounts of immunoglobulins. In this case, a person could have an allergy that is not reflected by the total IgE test result.
The total IgE test measures the overall quantity of immunoglobulin E in the blood, not the amount of a specific type. It can be used to detect an allergic response in the body rather than a specific allergy. This test may compliment the information provided by allergy tests that detect allergen-specific IgE. How is the sample collected for testing?
