Confidentiality is built in — orders are private and results are accessed securely. Because individual sites vary, double-check the lab's own guidance on preparation, timing, and cost.

What it measures

  • Penicillin V-specific IgE — An antibody that can trigger immediate allergic reactions.
  • Total IgE — A general measure of allergic antibody levels in the blood.
  • Penicillin V IgG — An antibody that may indicate past exposure without allergy.
  • Penicillin V IgM — An antibody that can appear early after exposure.

Preparation

No fasting or special preparation is usually required. Tell your doctor about all medicines you take, especially antihistamines, as they may affect test results.

Results and what they mean

Results are reported as levels of specific antibodies, often with a reference range. A high level may suggest allergy, but only a clinician can interpret the results with your history. This is general information, not medical advice; discuss your results with a qualified healthcare provider.

Results are typically available in 1 to 3 business days after the blood sample is collected.

Is this test painful?

It is a standard blood draw, which may cause brief discomfort. There are no other side effects.
