Are skin-prick allergy tests accurate/trustworthy? I still get occasional hives & worry about foods, but my allergy test showed no food reactions.

Are skin-prick allergy tests accurate/trustworthy? I still get occasional hives & worry about foods, but my allergy test showed no food reactions.

Hives - not allergy: Prick skin tests are helpful if positive and the patient has a history suggestive of allergy. They are insufficient to make a diagnosis of food allergy by themselves.

Occasional atypical lymphocytes present, & normochromic rbc's, along with LDH of 280 (normal high is 237) and swollen mediastinal lymphnodes, history asthma only, w/ chronic hives, what's this point 2?

Depends: These results can bee found if you are recovering from illness. Since you have a history of asthma with chronic hives, these findings can also be reactive to hypersensitivity. You should be monitored by repeat labs to see if these changes resolve with time. Follow with your PCP. ...Read more

Don't know: You need to consult an allergist. The problem may just be hives but given all of the other issues, one needs to rule out more serious conditions as well. At this time, it does not appear that your problem is related to anaphylaxis. ...Read more
