It is usually ordered when a person has unexplained skin, respiratory, or systemic symptoms that may be triggered by formaldehyde exposure.

What it measures

  • Formaldehyde-specific IgE — Amount of allergic antibody (IgE) in your blood that binds to formaldehyde.
  • Total IgE — Overall level of allergic antibodies, which helps interpret the specific result.
  • Eosinophil count — Number of a type of white blood cell often linked to allergic reactions.

Who it is for

This test is typically ordered by an allergist, immunologist, or primary care clinician when a patient reports symptoms that may be related to formaldehyde exposure.

Preparation

No fasting or special preparation is needed. Tell your clinician about any medications you take, as some antihistamines may affect test results.

Results and what they mean

Results are reported as a level of formaldehyde-specific IgE, often as a number with a reference range. A clinician interprets the result along with your symptoms and exposure history. This information is not medical advice; only a qualified healthcare professional can diagnose an allergy.
