Call Allergy Blood Testing in Laguna Niguel, CA
Blood testing measures antibodies in a sample; it does not diagnose an allergy on its own. This page explains how to prepare a clear history so the Laguna Niguel team can discuss whether a blood test would answer your question.
Clinical Overview
About Allergy Blood Testing in Laguna Niguel
A blood sample can show whether the immune system has made specific IgE antibodies to a substance. Many people have such antibodies without any symptoms, so a result is read together with what actually happened when the person was exposed.
Helpful preparation includes earlier blood results with their dates, a list of antihistamines or other medicines you take, and a plain account of the reaction you are worried about. Ask the office whether the medicines you take affect the type of test being considered.
Cheryl Carr, FNP-C, who lists food allergies and environmental allergies among her interests, and Vinay Mehta, MD, both work at the Laguna Niguel office. Call (949) 364-2900 on a weekday between 8:00 AM and 5:30 PM to ask whether blood testing can be arranged there.

Frequently Asked Questions
Allergy Blood Testing Questions in Laguna Niguel
Not necessarily. A positive result shows sensitization, which can occur without symptoms. The clinician interprets it alongside your history of reactions to decide whether it is clinically meaningful.
Blood tests are generally less affected by antihistamines than skin tests, but you should not change any medicine without asking. Call the Laguna Niguel office and confirm the instructions for your situation.
Bring complete reports with dates and reference ranges, not just a portal summary, along with a list of current medicines and a short description of the reaction that prompted testing.
