This page explains how to prepare for a Trichoderma Viride Allergy Test, what the test measures, and what to confirm with the collection lab. The Trichoderma Viride Allergy Test is a blood test that checks for an allergic response to Trichoderma viride mold spores.
Trichoderma Viride Allergy Test: what it measures
It measures the amount of specific IgE antibodies directed against Trichoderma viride mold spores in your blood. Elevated levels can indicate sensitization to this mold. Results are interpreted alongside your symptoms and history by your clinician.
- Trichoderma viride specific IgE
- Total IgE (if included)
- Other mold IgE allergens (if panel)
Getting ready for the Trichoderma Viride Allergy Test
For a typical order, no unusual preparation is needed before this blood draw. Confirm any timing or fasting guidance directly with the collection site.
- No special diet changes are usually required before this test.
- Stay hydrated by drinking water before your appointment to help with the blood draw.
- Take your regular medications unless your clinician advises otherwise.
- Tell the collection staff about any medications, supplements, or recent illness.
- Confirm the appointment time and any site-specific instructions with the lab.
Fasting, timing, sample type, and what to bring
Fasting
Fasting is generally not required for this allergy blood test, but some labs may have their own guidance. Confirm with your lab.
Best time to collect
This test can typically be collected at any time of day. If your clinician wants to compare results with prior tests, try to collect at a similar time.
Sample type
Blood draw. The collector will explain the process before starting.
What to bring
- Your order confirmation email, in case the collection site asks to see it
- 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
- 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
- Water to drink before the draw and a light snack for afterward, if your test requires fasting
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.
The collection visit, step by step
A healthcare professional collects a small blood sample from a vein in your arm using a needle. The sample is sent to a laboratory for analysis, and the draw usually takes only a few minutes.
Details worth confirming with the collection lab before your visit:
- Does this test require fasting or any timing restrictions?
- When should I expect my results to be available?
- Are there any medications I should pause before this test?
Why a clinician may order this test
A clinician may order this test when you have ongoing allergy symptoms and mold exposure is suspected. It helps determine whether Trichoderma viride specifically is contributing to your symptoms.
What results mean
Reference ranges and reporting formats vary by laboratory, so results should be interpreted in the context of your symptoms and history. Your clinician will explain what your specific values mean for you.
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?
Fasting is usually not required, but some labs may have specific instructions. Confirm with your collection site before your appointment.
How long do results take?
Turnaround is typically one to three business days, though this can vary by laboratory. Your ordering clinician will review and share results with you.
Can I take my regular medications?
In most cases yes, but certain medications may affect allergy testing. Ask your clinician or the lab whether any of your medications should be adjusted.
What does a positive result mean?
A positive result suggests sensitization to Trichoderma viride mold, but it does not by itself confirm an allergy. Your clinician interprets it with your symptoms and exposure history.
