<s>[INST] My wife has been suffering from Urticaria for nearly 10 years. In order to get a list of triggers that cause this problem, we intend going through a comprehensive test. I would like to know names of reliable labs that conduct this test in any part of India. We are aware of some triggers that cause it for her: Most of the pain killers, e.g. Brufen; severe cold and hot weathers; some food items like, peanuts, beet root, brinjal; excessive physical strain. Would like to know more of this list through a proper test and diagnosis. Recently she has gone through an allergy test (Allergy Comprehensive Profile Adult) in Lal s pathology lab in Delhi, however, without any satisfactory result. The list came out of the test was quite small and limited - did not even include the triggers we have been already aware of. Came to know through some known contacts that there are labs in India that do these tests covering nearly 300 to 400 different types of potential triggers. However, couldn t source a good name - someone mentioned Nanavathi Hospital, Mumbai. Not checked with them yet. Would like to know if some one help us find a good lab. [/INST] hi lab like RANBAXY ,RELIGARE are doing allergy test with different allergen more then 200. it has branch all over india .so take contact no from net and ask them detail. there are different allergen like food ,inhale ,drug,chemical etc one thing i like to tell  u that urticaria is unpredictable condition and take 2 month to 20 yr to resolve so take only antihistamine tab for it ,do not take steroid regularly </s>
