Will medication affect my test results in any way?

There are a few types of medication that may stop your test from being accurate. Immunosuppressant medications can also affect the results of the testing, we advise that you check with our team prior to testing regarding medications. Antihistamines have been shown to affect results; we advise stopping antihistamine use for 3-5 days before taking your sample; however, we would recommend seeking advice from a medical professional before changing any medication.
