Are antibiotics and/or antifungals going to interfere with the Organic Acids Test (OAT)?
Antibiotics and antifungal will not directly interfere with the OAT unless they contain apples, grapes, pears or cranberries. It is important that the patient and practitioner consider why the test is being administered in order to determine whether or not the patient should refrain from antibiotics and antifungals. For example, a practitioner may want to know if a certain therapy is effective. In this example, it would be perfectly acceptable to remain on the therapy during collection. Separately, a patient may want to understand their metabolic condition without the aid of therapy. In this case, it is best to remove the antibiotics or antifungals for 1-2 weeks prior to testing.
