ROUTE MAP TO SAFER HOME · SYMPTOMS · POSSIBLE EXPOSURE
Could something in your home be affecting your health or recovery?
Doctors treat the symptoms. But if the cause is hidden in your home, recovery stalls and treatments fall short. We connect your health history with the environment around you, identifying symptoms or exposure you may not have considered, so the real culprit is finally exposed. These apps provide you with the knowledge and information to make important choices.
OUR OBJECTIVE
From scattered facts to a clearer, evidence-led picture.
Review the facts and history, add observations and risk factors, identify potential exposure sources, and use proportionate evidence to confirm or exclude them and reduce risk. Give you and your healthcare professional a clearer data-driven record to support better-informed diagnosis and treatment decisions.
From Health concerns to Diagnosis and Decontamination — One clear Route
Whether you are a DIY homeowner or a healthcare professional, this site helps you identify possible exposure symptoms, find the likely source, know how and what to sample, interpret the results, plan your next steps and verify decontamination. Expand any step below. Guidance to support you and your healthcare professional. NOT MEDICAL ADVICE
Symptom mapping
Record health changes against occupancy and timeline to spot building-related patterns.
Exposure indicators
Common mold, damp and biotoxin exposure markers explained in plain English for DIY users and clinicians.
When to escalate
Clear guidance on which symptom clusters warrant testing or professional clinical review.
Discover · Observe · Prove
A fast-track route that looks beyond what is immediately visible. DOP helps you identify possibly hidden clues and symptoms, organise them, and use proportionate evidence to confirm or exclude a source — putting you in the driving seat before you spend on contractors or testing you may not need.
Discover
Identify possibly hidden clues — subfloors, cavity voids, HVAC ducts and aerosolized mycotoxins you may not have considered.
Observe
Record symptoms, chronology, moisture and exposure pathways so scattered facts become a structured, dated picture.
Prove
Use proportionate evidence — sampling, lab interpretation and the connected Parallax route — to confirm or exclude a source.
