Allergy testing: 6 months ago J's level for peanuts was 3.78 - and today we got the results back from his most resent blood work test and unfortunately his level went up to 4.09. (I believe the range goes from 0 to 9.5; 0 being no allergies and 9.5 being extremely allergic) The doctor will see him again in 6 months...oh the joys. No peanuts or any nuts for him...poor guy.
