I have 347u/mL IgE total nd had specific allerfy tests and got dermatophagoides pter (d1) 1.8U/l class 2 , dermatophagoides farinae (d2) 1.5 U/l class 2, indicator 96U/l class 6. What do these 3 mean?

A total IgE test may be ordered when a person has periodic or persistent symptoms that may be due to an allergic reaction, especially when the potential allergen cannot be identified based upon the history of the symptoms and physical examination. IgE can also be increased with parasitic infections, so a total IgE test is sometimes used as a screening test if a parasitic infection is suspected.
An increased total IgE level indicates that it is likely that a person has one or more allergies. Allergen-specific IgE levels will increase after an exposure to a particular allergen, and then decline over time, thus affecting the total IgE level. If a person is allergic to a seasonal substance, such as pollen, then both the specific IgE and total IgE would be expected to be elevated during the time of year when the allergen is present. If someone is allergic to something that they are constantly around, such as mold in a house or cat dander, then the total IgE level may be persistently increased.
An elevated level of total IgE indicates an allergic process is likely present, but it will not detect the exact substance what a person is allergic to.
In your case, and based on the last three tests, you are allergic to house dust mite (Dermatophagoides pteronyssinus and Dermatophagoides farina); d1 and d2 are their test codes, respectively.
Studies of house dust-allergic individuals have shown that House dust mites cause symptoms such as perennial-type asthma, rhinitis (nasal itchiness, sneezing, runny nose) and conjunctivitis (eye redness, itching, and excessive tearing), often with nocturnal or early morning episodes.
These are very specific tests and need to be interpreted by an allergologist (allergy specialist) in order to ensue the right management plan, especially that house dust mite are ubiquitous and will continue to cause you allergy symptoms.
