Below is a plain-language prep guide for the cladosporium herbarum allergy test, including sample type and timing basics. The Cladosporium Herbarum Allergy Test is a blood test that checks for an allergic sensitization to Cladosporium herbarum mold spores.
What the results reflect
It looks for Cladosporium-specific IgE antibodies in the blood. The level helps a clinician judge whether this mold may be behind your symptoms.
- Cladosporium herbarum IgE
- IgE antibody level
- Sensitization status
Preparation checklist for the Cladosporium Herbarum Allergy Test
In most cases nothing extra is needed. Ask your lab about any timing or fasting instructions before your visit.
- Ask your lab if fasting applies.
- Continue your usual medicines unless advised otherwise.
- Disclose allergy medications to the collector.
- Wear short sleeves for an easy draw.
- Bring your identification and test order.
Fasting, timing, sample type, and what to bring
Fasting
Fasting is not normally required for this IgE test; confirm with your lab.
Best time to collect
The draw can happen at any time of day, and a morning slot often helps with same-day processing.
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 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
- A government-issued photo ID (most collection sites verify identity at check-in)
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 small blood sample is drawn from a vein in your arm, taking about a minute. The lab tests for Cladosporium-specific IgE.
Details worth confirming with the collection lab before your visit:
- Ask whether fasting is required.
- Ask when results are ready.
- Ask if medicines affect the test.
Why a clinician may order this test
It is ordered when indoor or outdoor mold exposure brings on sneezing, congestion, or asthma-like symptoms. It may be part of a mold allergy panel.
Reading your results responsibly
Results are reported as an antibody level with ranges that vary by lab. Your clinician reads it with your symptoms and exposure history, because a positive test does not always confirm a clinical allergy.
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.
