Fasting, timing, sample type, and what to bring
Fasting
Fasting is typically not required for this IgE test; confirm with your lab.
Best time to collect
Any time of day is acceptable. Testing is often considered after known exposure to a damp or water-damaged space.
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 collector draws a small blood sample from your arm in about a minute. The lab measures Stachybotrys-specific IgE.
Details worth confirming with the collection lab before your visit:
- Ask whether fasting applies.
- Ask when results are ready.
- Ask if medicines affect the test.
Why the Black Mold (Stachybotrys chartarum) Allergy Test may be ordered
It is ordered when a person with mold exposure develops symptoms such as congestion, coughing, or asthma-like breathing changes. It can also be part of a broader mold allergy panel.
What results mean
The lab reports an antibody level with ranges that vary by lab. Your clinician reads it with your exposure history and symptoms, since sensitization does not always mean 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.
