This page explains how to prepare for a Trichophyton Mentagrophytes Allergy Test, what the test measures, and what to confirm with the collection lab. This test uses a blood sample to check for an allergic response to Trichophyton mentagrophytes, a common mold.

What this test looks at

The test measures the level of IgE antibodies your blood produces in response to Trichophyton mentagrophytes. Elevated levels can suggest an allergic sensitization to this mold. Results are interpreted alongside your symptoms and history.

  • Trichophyton mentagrophytes IgE
  • Total IgE
  • Other mold IgEs

Preparation checklist for the Trichophyton Mentagrophytes Allergy Test

Routine orders for this test rarely require special preparation. Confirm any timing or fasting details with the collection lab when you book.

  1. Confirm with the lab whether fasting is needed for your specific order.
  2. Stay hydrated before your appointment unless the lab tells you otherwise.
  3. Wear a short-sleeved shirt to make a blood draw from your arm easier.
  4. Bring a list of medications and supplements you take, including allergy medicines.
  5. Tell the collector about any recent illness, fever, or skin infection.
  6. Arrive a few minutes early to complete any paperwork.

Fasting, timing, sample type, and what to bring

Fasting

Fasting is generally not required for routine allergy blood testing, but some orders may combine other tests that need it. Confirm with your lab.

Best time to collect

A blood sample can usually be collected at any time of day. If other tests are ordered at the same time, the lab may suggest a morning appointment.

Sample type

Blood draw. The collector will explain the process before starting.

What to bring

  • Your printed lab order or requisition form — the ordering physician prepares it for you after you order, and you print it (or fax it from your account) before visiting
  • Your order confirmation email, in case the collection site asks to see it
  • Water to drink before the draw and a light snack for afterward, if your test requires fasting
  • A government-issued photo ID (most collection sites verify identity at check-in)
  • A written list of the medications and supplements you currently take
  • A short-sleeved or loose-sleeved shirt for an easy blood draw

You do not need an insurance card or a payment method at the collection site: the lab does not bill insurance, and you pay at order time, so there is no copay or deductible. The lab also provides the physician's requisition, so you do not need a separate doctor's referral.

Order process and what-to-bring details reflect the lab's published instructions, paraphrased in our own words. Confirm final requirements with the collection lab that will perform your draw.

What happens during the collection visit

A trained collector cleans the skin, usually on the inside of your elbow, and inserts a small needle to draw a blood sample. The sample is then sent to a lab for analysis, and the draw typically takes only a few minutes.

Details worth confirming with the collection lab before your visit:

  • Does my order require fasting?
  • When will results be available?
  • Should I stop any medications before this test?

Why the Trichophyton Mentagrophytes Allergy Test may be ordered

A clinician may order this test when you have ongoing skin, hair, or nail symptoms that could be linked to a mold sensitivity. It can also be part of a broader allergy evaluation.

What results mean

Reference ranges and reporting formats vary by laboratory, so results should be interpreted using the range provided with your report. Your clinician will explain what your result means for your situation.

General test information is compiled from publicly available reference material, including MedlinePlus (medlineplus.gov) and the Centers for Disease Control and Prevention (cdc.gov), and is reviewed for clarity. Preparation and what-to-bring details reflect the lab's published instructions, paraphrased into our own words. Preparation instructions, timing, and pricing vary by collection lab — always confirm them with the lab that will perform your draw.

Common questions

Frequently asked questions

Do I need to fast for this test?

Routine orders for this test rarely require fasting. If other tests are ordered at the same time, the lab may ask you to fast, so confirm with your collection lab.

How is the sample collected?

A blood sample is drawn from a vein, usually in your arm. The process is quick and done by a trained collector.

How long do results take?

Turnaround is typically one to three business days, though this can vary by laboratory. Ask your lab for the expected timeline.

Can I take my allergy medication before the test?

Ask your clinician or the lab whether your medications should be continued or paused. Do not change medications without guidance.
