Mold Testing Explained: When, Why, and How to Do It Right
Author: Dr. Kolin Durrant, Integrative Care Director, Doctor of Acupuncture & Chinese Medicine
Mold is one of the most underestimated threats to physical health and wellbeing. While many associate mold with visible growth in damp corners, the true risks are often hidden. Mold spores can circulate invisibly through indoor air, settle in household dust, and contribute to chronic health conditions that are difficult to trace. Mold testing offers a scientific, evidence based approach to identifying exposure and initiating appropriate treatment or detoxification strategies.
Although the topic has gained attention recently, holistic health providers have long recognized the importance of screening for environmental toxicity as part of a whole person care model. This guide explains when to consider mold testing, why it matters, and how to approach it effectively, with a focus on both environmental assessments and clinical testing for biotoxin illness.
Why Mold Testing Matters for Health and Wellbeing
Indoor air quality is one of the most overlooked environmental factors influencing long term health. According to the U.S. Environmental Protection Agency, Americans spend nearly ninety percent of their time indoors, where pollutants such as mold can be two to five times more concentrated than outdoor levels (EPA Indoor Air Quality).
In some individuals, exposure to mold causes symptoms like sinus congestion, headaches, and fatigue. In others, particularly those with underlying immune or inflammatory conditions, it can trigger more serious issues such as shortness of breath, histamine reactions, neurological symptoms, or persistent infections. Mold exposure has also been linked to cognitive symptoms such as brain fog, poor sleep, mood changes, and trouble concentrating.
Mold testing is the foundational step in identifying whether you are living or working in an environment that may be contributing to illness. Without testing, any detox or treatment plan may fall short due to continued exposure.
Home Mold Testing Versus Clinical Mold and Biotoxin Testing
It is important to distinguish between testing your living environment and testing your body for mold related illness. Each serves a unique purpose:
Home Mold Testing
Environmental testing identifies whether you are currently living in or exposed to a contaminated environment. This includes air, dust, or surface testing performed inside your home, office, or building. These results guide decisions around remediation, relocation, or prevention.
The most comprehensive and accurate home testing currently available is offered by EnviroBiomics. Their test kits can screen for:
HERTSMI-2: A scoring system used to assess potential for mold related illness based on five highly toxigenic molds
ERMI: Environmental Relative Moldiness Index, offering a broader DNA analysis of indoor mold burden
Actinobacteria: Associated with chronic inflammatory responses and not typically detected through standard mold testing
Endotoxins and Mycobacteria: Microbial toxins associated with immune system dysregulation
These tests rely on dust sampling using a Swiffer or vacuum collection and are ideal for determining whether your living or working space is safe, especially if you have a history of water damage or unexplained symptoms.
Clinical Mold or Biotoxin Testing
Clinical testing evaluates how your body has responded to mold exposure. This may include:
Mycotoxin testing (urine based): Identifies mold toxins your body has absorbed and is attempting to eliminate
Inflammatory markers such as TGF beta 1, MMP9, C4a, and VEGF
Genetic susceptibility testing (HLA DR): Determines if your body is more prone to retain biotoxins
Visual Contrast Sensitivity (VCS) Test: A simple, non invasive test that evaluates the function of your optic nerve and neurological system. Mold exposure may impair contrast sensitivity due to toxin effects on capillary blood flow
These tests are interpreted by holistic or functional medicine practitioners to create a personalized detoxification and recovery plan.
When to Consider Mold Testing
You do not need to see or smell mold for it to be a problem. You should consider mold testing if:
You experience chronic fatigue, sinus issues, headaches, or unexplained inflammation
You have been diagnosed with chronic inflammatory conditions, mast cell activation, or autoimmune disease
Your home or office has a history of water damage, roof leaks, or HVAC problems
You are moving into a new residence or office and want to ensure it is free from contamination
You have tried conventional or holistic treatments without full resolution of symptoms
Early detection through mold testing can help prevent years of misdiagnosis, ineffective treatment, and deteriorating health.
The Science Behind Mold and Human Health
The medical literature increasingly supports the connection between environmental mold exposure and chronic illness. A 2020 study published in Frontiers in Immunology found that exposure to indoor molds disrupts immune regulation and triggers inflammatory cytokines in genetically susceptible individuals (Frontiers in Immunology – Immune Responses to Mold). The World Health Organization has linked mold contaminated indoor environments to asthma, chronic bronchitis, and other respiratory illnesses (WHO Guidelines for Indoor Air Quality: Dampness and Mould).
These findings support mold testing as a vital preventive and diagnostic tool, not just a response to visible contamination.
Benefits of Mold Testing
Protects your health by identifying a major environmental burden that may be contributing to symptoms
Supports detoxification by ensuring the body is not being re exposed during treatment
Improves clinical outcomes in both conventional and holistic therapies
Protects children, pets, and vulnerable adults from toxic exposure
Preserves property value by catching contamination before structural damage worsens
Whether testing your home or body, mold testing provides clarity and direction in your healing process.
Why Professional Mold Testing Is Recommended
While over the counter kits may seem convenient, they often produce limited or misleading results. Professional testing offers:
More accurate collection and laboratory analysis
Comprehensive identification of mold species and mycotoxin presence
Better data for interpreting long term exposure risks

At Saffron and Sage, we also incorporate mold and biotoxin testing into a larger framework of integrative care, including immune support, detox strategies, and nervous system regulation.
Mold in San Diego: Local Considerations
While San Diego is known for its dry, mild climate, many local homes experience moisture problems due to coastal fog, older buildings, or poor ventilation. Properties close to the ocean or constructed without modern building materials may harbor hidden mold, especially in crawl spaces, attics, or air conditioning ducts.
This makes mold testing an important part of preventive care for San Diego residents, even when symptoms are not severe.
The First Step in Healing: Know Your Environment
Mold is often invisible, odorless, and underestimated. Yet it can be one of the most powerful disruptors of health and recovery. Testing provides an objective foundation for taking action, whether that involves home remediation, relocating temporarily, or beginning a clinical detox protocol under medical supervision.
At Saffron and Sage, we believe that the environment you live in is just as important as the treatments you receive. When these two are aligned, healing becomes possible.
