Quick Answer
Elevated in active mold exposure and inflammation
Availability
request through clinician
Result Context Range
85–332 ng/mL
What This Helps Measure
Elevated in active mold exposure and inflammation
Which theories this can evaluate
This measurement is most useful when your pattern already suggests why it belongs in the workup.
What It Does Not Prove
One biomarker rarely settles the full question on its own. It is most useful when the pattern already suggests why it matters.

Visual Guide
How To Prepare
- •Blood draw; no fasting required.
- •Avoid intense exercise 24 hours before, as it can elevate levels.
How To Use This Test Well
Step 1
Book correctly
Request MMP-9 (Matrix Metalloproteinase-9) with required timing/prep (fasting and time-of-day when relevant).
Step 2
Capture the result exactly
Save numerical value, units, lab reference interval, and collection time.
Step 3
Interpret with pattern context
Compare results against symptom timing and related markers before changing plan.
What To Watch For
- →MMP-9 rises in many inflammatory states (infection, autoimmune, cancer), not just CIRS.
- →Normal MMP-9 does not rule out CIRS.
- →Results vary by lab; use same lab for tracking over time.
Result Context
normal
Within lab range; compare with your target context (85–332 ng/mL).
Result may be acceptable but still needs symptom correlation and trend review.
borderline
Near thresholds or inconsistent with symptoms.
Consider repeat testing, timing factors, and related markers before conclusions.
abnormal
Outside expected range or clearly discordant with baseline.
Use clinician-guided follow-up and structured differential workup.
What To Do Next
- •Use as one piece of a multi-marker panel, not a standalone diagnostic.
- •If elevated, rule out other inflammatory causes before attributing to mold.
