Acremonium Kiliense C Acremonium IgG
It measures IgG antibodies to Acremonium kiliense to assess immune exposure patterns, with convenient ordering and clear results through Vitals Vault/Quest.
This panel bundles multiple biomarker tests in one order—your report explains how results fit together.
This test looks for IgG antibodies your immune system may produce after exposure to a specific mold-related fungus called Acremonium kiliense. It is not a “mold toxin” test, and it does not prove an active infection.
An Acremonium kiliense IgG result is most useful when you are trying to connect a pattern of symptoms and environment (home, workplace, hobbies) with immune sensitization. It can also help your clinician decide what follow-up testing makes sense.
Because antibody results can be influenced by timing and by other health conditions, the best next step is usually to interpret this test alongside your symptoms, your exposure history, and other labs—not as a standalone diagnosis.
Do I need a Acremonium Kiliense C Acremonium IgG test?
You might consider this test if you have ongoing respiratory symptoms that seem tied to certain buildings or environments, such as persistent cough, wheezing, chest tightness, shortness of breath, or recurring “flu-like” episodes after being indoors. Some people also pursue it when they have a known dampness or mold problem at home or work and want objective data to discuss with a clinician.
This marker is sometimes used as part of an evaluation for immune sensitization to environmental fungi, including conditions like hypersensitivity pneumonitis (an immune-mediated lung inflammation). If your clinician is already working up chronic sinus issues, asthma-like symptoms, or unexplained inflammatory symptoms, an organism-specific IgG can be one piece of the puzzle.
You may not need this test if your main concern is acute allergy symptoms like sneezing, itchy eyes, or hives right after exposure. Those are more often associated with IgE-mediated allergy testing rather than IgG.
Testing can support clinician-directed care and exposure planning, but it cannot diagnose mold illness, infection, or a specific building as the cause of your symptoms on its own.
This is a laboratory-developed test performed in a CLIA-certified lab; results should be interpreted in clinical context and are not a standalone diagnosis.

Key benefits of Acremonium Kiliense C Acremonium IgG testing
- Adds objective data when you suspect a damp-building or mold exposure pattern.
- Helps distinguish IgG immune sensitization questions from classic IgE allergy testing.
- Supports a clinician’s evaluation of immune-mediated lung inflammation when symptoms and imaging suggest it.
- Can be used to track changes after exposure reduction, remediation, or relocation when retesting is appropriate.
- Provides organism-specific information that may guide whether broader fungal antibody testing is worthwhile.
- Helps you interpret symptoms in context by pairing results with exposure history and other inflammatory markers.
- Creates a baseline result you can store, share, and trend over time in your Vitals Vault account.
What is Acremonium Kiliense C Acremonium IgG?
Acremonium kiliense is a species within the Acremonium genus, a group of environmental fungi that can be found in soil and in damp indoor environments. When you inhale fungal particles or fragments, your immune system may respond by producing antibodies.
IgG (immunoglobulin G) is the most common antibody class in your blood. An Acremonium kiliense IgG test measures whether you have IgG antibodies that bind to antigens from this organism. A higher result generally suggests your immune system has recognized this exposure at some point.
Importantly, IgG antibodies do not automatically mean you are “allergic,” and they do not prove active infection. In many cases, IgG reflects exposure and immune recognition, which may or may not be clinically relevant depending on your symptoms, timing, and other findings.
How this differs from IgE allergy testing
IgE testing is designed to evaluate immediate-type allergy, where symptoms such as sneezing, itching, hives, or asthma flares can happen quickly after exposure. IgG testing is more often used to explore longer-term exposure and immune sensitization patterns, including delayed or recurrent respiratory symptoms. The two tests answer different questions, and one is not a substitute for the other.
Where this test fits clinically
Clinicians may use organism-specific IgG results as supportive evidence when evaluating suspected hypersensitivity pneumonitis or other exposure-related inflammatory conditions. The diagnosis typically relies on a combination of history, imaging, lung function testing, and response to exposure avoidance—not antibodies alone.
What do my Acremonium Kiliense C Acremonium IgG results mean?
Low Acremonium kiliense IgG
A low or negative result usually means the lab did not detect a meaningful level of IgG antibodies to Acremonium kiliense at the time of testing. This can happen when you have not been exposed, when exposure was minimal, or when your immune system did not mount a detectable IgG response. A low result does not rule out symptoms from other molds, non-mold triggers, or a different immune pathway such as IgE-mediated allergy.
In-range (reference range) Acremonium kiliense IgG
An in-range result generally indicates no strong evidence of elevated IgG sensitization to this specific organism compared with the lab’s reference population. If you still have symptoms, your clinician may focus on other exposures, other fungal species, or non-environmental causes. “In range” does not guarantee that your environment is safe or that mold is not present; it only speaks to this one antibody measurement.
High Acremonium kiliense IgG
A high result suggests your immune system has produced more IgG antibodies to Acremonium kiliense than expected for the reference range, which is consistent with prior or ongoing exposure. Whether that exposure is clinically important depends on your symptoms, timing, and other findings such as imaging or lung function. Elevated IgG alone does not confirm hypersensitivity pneumonitis or an active fungal infection, but it can strengthen the case for deeper evaluation and exposure control steps.
Factors that influence Acremonium kiliense IgG
Antibody levels can vary with the intensity and duration of exposure, and they may change slowly over weeks to months after exposure reduction. Cross-reactivity can occur, meaning antibodies may partially react to related fungal antigens, which can blur organism-specific conclusions. Immune status matters too—immunosuppressive medications or immune deficiencies can lower antibody responses, while chronic inflammatory conditions can complicate interpretation. Lab methods and reference ranges differ, so it is best to compare your result to the range printed on your report and trend using the same lab when possible.

Frequently Asked Questions
What does an Acremonium kiliense IgG test measure?
It measures IgG antibodies in your blood that bind to antigens from Acremonium kiliense. The result reflects immune recognition of exposure, not a direct measurement of mold in your body or your home.
Does a high Acremonium IgG mean I have mold toxicity or a fungal infection?
Not by itself. A high IgG suggests exposure and immune response, but it does not prove toxin-related illness or an active infection. Your clinician typically considers symptoms, imaging, and other tests before making a diagnosis.
Is this the same as a mold allergy test?
No. Mold allergy testing usually focuses on IgE antibodies, which are linked to immediate-type allergic reactions. IgG testing is used more for exposure/sensitization patterns and can be supportive in certain inflammatory lung evaluations.
Do I need to fast before this blood test?
Fasting is not usually required for an IgG antibody test. If you are getting other labs at the same visit, follow the fasting instructions for the full set of tests you ordered.
When should I retest Acremonium kiliense IgG?
Retesting is most useful when there has been a meaningful change in exposure, such as remediation, relocation, or workplace changes, and you are tracking symptom response. Because IgG can change slowly, clinicians often wait weeks to a few months, depending on your situation.
What other tests are commonly ordered with this?
Depending on your symptoms, your clinician may consider additional fungal IgG antibodies, IgE allergy testing, inflammatory markers, or pulmonary evaluation such as spirometry and imaging. If digestive symptoms or autoimmune concerns are present, different companion tests may be more relevant.
