###Human: Had an allergy blood test. Are the numbers ranging between 0 and 0. 75 kU/L normal? ###Assistant: Hello. Let me help you. The IgE value is within normal limits. Moreover, the total serum IgE values are not very indicative, rather specific IgE levels are important. Specific IgE levels should be inferred in relation to the particular allergen. Each allergen level may be different. Currently, the most accepted form of testing allergy is the skin prick testing which is the gold standard. We do specific IgE blood tests only on those patients in whose skin prick test is contraindicated like pregnant ladies, etc. Your specific IgE levels need to be assessed in relation to the allergen. Can you share with us the whole report? Can you describe your symptoms to us? Have you had this problem since long? What medicines are you currently on? Are your problems seasonal or perennial? Is there breathing trouble or skin problems also?
