Educational information only
The information on this website is provided for general educational and informational purposes only. It is not medical advice, a diagnosis, a treatment plan, a prescription, or a substitute for an individualized assessment by a qualified health professional.
Reading, using, or communicating with this website does not create a physician–patient, clinician–patient, therapist–patient, pharmacist–patient, or other professional health-care relationship.
Do not use this website for emergencies
This website is not an emergency service and is not monitored for urgent medical requests. In the United States, call 911 or seek emergency care for a medical emergency. In another country, use the local emergency number or emergency service.
Examples of symptoms that may require urgent assessment include severe or rapidly worsening pain, heavy bleeding, fainting, difficulty breathing, rapidly progressive swelling, fever with significant pelvic or abdominal pain, confusion, or another serious acute reaction. This list is not exhaustive.
General information cannot account for an individual situation
Health decisions can depend on age, pregnancy, breastfeeding, menopause, allergies, medical history, examination findings, medications, laboratory results, immune status, diabetes, kidney or liver disease, and other facts that this website does not know.
Do not start, stop, delay, combine, or change a medicine, supplement, test, procedure, or treatment solely because of information on this website. Follow the current product label and the instructions of the professional responsible for your care.
Tests, products, and services have limitations
Home tests, laboratory tests, symptom checklists, pH strips, molecular panels, and microbiome reports can produce false-positive, false-negative, invalid, incomplete, or clinically uncertain results. Detection of an organism does not always mean that it is causing symptoms, and a negative result does not necessarily rule out disease.
Product descriptions, prices, availability, laboratory credentials, privacy terms, and service features can change. A link to a product, laboratory, company, study, or third-party website is provided for reference and does not constitute endorsement, certification, or a guarantee of safety, effectiveness, accuracy, privacy, or suitability.
Sources and updates
The website aims to use reliable sources and to identify important uncertainty, but medical knowledge, guidelines, product labels, and regulations change. Content may become incomplete or outdated. Publication or revision dates do not guarantee that every linked source remains current.
No guarantee of outcome
No result, symptom improvement, diagnosis, treatment response, ranking, laboratory performance, or health outcome is promised or guaranteed. Different people can respond differently to the same product, test, or treatment.
Limitation of liability
To the maximum extent permitted by applicable law, the website, its publisher, contributors, contractors, and service providers are not liable for loss, injury, damage, delay, expense, or other consequence arising from reliance on, use of, or inability to use the information on this website or a linked third-party service.
Nothing in this disclaimer excludes or limits liability that cannot lawfully be excluded or limited, and nothing in it removes rights that applicable law makes non-waivable.
Your responsibility
You are responsible for deciding whether and how to use the information, for obtaining appropriate professional assessment when needed, and for checking the current instructions, warnings, contraindications, and privacy terms of any product, test, or service.
