Antihistamine and RAST Test-how long without??
Good morning! Well, I had planned on taking both my kids for their RAST test this morning at the outpatient lab at the Hospital but now we may have to wait....need some help from all of you!
Yesterday a.m. my son received his daily dose of Claritin for his seasonal allergies. I seem to recall my allergist telling me years ago that they cannont have any antihistamine's in their system or the RAST test will be null/void. BUT, I don't remember how long it has to be out of their system? A day? A week? My 7yr old DD is also getting her RAST done and she recieved Benedryl on Thursday due to a hives outbreak at school from peanut/nut traces. SOOOO...should I wait to take them?? Or can I still go today??
I called my Pediatritions office, because Allergist is closed on Saturday, and they had NO IDEA. I called the QUEST LAB at the hospital, they didn't know either. They transferred me to the Chemistry Lab to talk to a Chemist and he didn't know either! AUGHHHH> So frustrating!!!
If any of you know the protocol for how long without antihistamine before a RAST test, it would be very helpful. I would love to take them today, if I could, while Hubby is home to help.
