• Serum total IgE blood test: every individual has immunoglobulin E. It is an antibody that is involved in the classic allergic reaction. The procedure measures the IgE in the blood. People with a high level of total IgE can develop allergy while others with average levels can also be susceptible to allergies. 
• Specific IgE blood test: doctors can recommend blood analysis, which comes within the ambit of serum total IgE. It is the IgE that works against individual allergens like grass pollen, peanut or penicillin, house dust, and others. In case individuals have skin conditions or take regular medicines, which interfere with the testing, an allergen blood test will be of some help. Moreover, they are a reliable option for children. The doctor will take the blood sample and send it directly to the laboratory. The lab then adds allergen to the model, and then the measurements are recorded.
• Food challenge test: people conduct this test with food allergies or possible medication. Sometimes, after performing a blood test and skin prick, the allergen is not diagnosed. It is here that the doctor will suggest an OFC or oral food challenge test. 

There are different kinds of oral food challenges, encompassing single-blind food challenges, comma open food challenge, and double-blind, placebo-controlled food challenge. Apart from this, insect sting tests and fire and sting are other reliable diagnostic procedures.
