Arithmetic and unit-conversion tools
These may be affected by inputs, units, conversion rules, and rounding.
Medical Disclaimer
This page explains the medical-use boundaries of QuickMedCalc calculators. The site helps users view public medical formulas, scoring methods, and calculation rules. An output is not a patient-specific diagnosis, prescription, or treatment recommendation, and the site cannot replace an applicable guideline, local process, or professional judgment.

What this disclaimer means
This Disclaimer explains reasonable boundaries for using website output; it does not mean that a calculator has no reference value. It also does not replace the population, formula version, source, and limitation notes on each calculator page. The Terms of Use describe access and legal-use conditions, while the Privacy Policy explains data handling.
Intended audience
QuickMedCalc is primarily intended for healthcare professionals, clinical learners, students, and adults reviewing public medical formulas. Other adults may view the pages, but should not use an output to diagnose or treat themselves, change a medicine, or direct another person's treatment. Pediatric calculators do not make this a service directed to children. A minor should not independently submit patient-identifying or personal information.
Not patient-specific medical advice
Calculator output is not medical advice, a diagnosis, a prescription, a treatment plan, a monitoring plan, or a referral, triage, or disposition decision. Use of the site does not create a doctor–patient relationship or another professional-service relationship. An email response from QuickMedCalc also does not provide patient-specific medical advice.
Emergencies
QuickMedCalc cannot determine whether a person is experiencing an emergency. Do not delay seeking help while viewing a page or calculating a result. If a situation may be urgent, contact local emergency services or a qualified healthcare professional immediately. The email routes described on the Contact page are not emergency channels and should not be used for urgent medical questions.
Professional judgment and care decisions
A result cannot alone decide diagnosis, treatment, prescribing, dose, monitoring, referral, triage, or disposition. Healthcare professionals need to consider the complete history, examination findings, laboratory and imaging information, changes in the patient's condition, current evidence, local guidelines, institutional processes, patient preferences, and the person's specific circumstances. A calculator may assist as a reference but cannot replace that assessment. Other users should consult an appropriately qualified healthcare professional.
Sources, versions, and possible errors
Calculator pages are prepared from checkable original publications, currently applicable guidelines, official policies, regulatory or manufacturer materials, and other authoritative sources as relevant. The site seeks to identify the currently relevant version and clearly label historical or superseded models.
Guidance, policies, formulas, reference ranges, and interpretation standards can change. Source and implementation checks and automated tests cannot eliminate formula, coefficient, or threshold errors; unit-conversion or input-definition problems; outdated sources; omissions; implementation defects; or unclear explanations.
QuickMedCalc does not guarantee that every page is always complete, error-free, or current for every country, institution, patient, or clinical setting. These limits are why pages identify sources and versions and provide a correction route. Read the Sources and Review Process and use the Contact page to report a concern.
Inputs, units, timing, and data quality
Check the calculator name and version, intended population and exclusions, input source, units, the meaning of age, weight, and published sex variables, specimen type, measurement timing, observation window, missing or unassessable items, minimum and maximum values or model clamping, rounding and display precision, and page-specific limitations.
Incorrect, outdated, or mismatched inputs can produce an unreliable result. Unit conversion cannot make an unsuitable measurement or specimen applicable. Do not combine different time points or assay methods without a valid reason. A displayed result does not verify that an input came from a real patient, the intended specimen, or a correctly functioning device.
Formula and model limitations
Scores and prediction models
These may depend on derivation and validation populations, outcome definitions, time horizons, missing items, and external validation.
Reference-range tools
These may vary with the laboratory, assay, age, published sex variable, region, and local reference interval.
Guideline or policy tools
These may change with version, region, institutional process, and publication date.
Historical formulas
These may reproduce a specific publication or earlier version without representing current recommended practice.
Medication and dosing calculations
For medicine or dose calculations, independently confirm the medicine name, formulation, concentration, weight basis, route, interval, maximum dose, kidney adjustment, liver adjustment, allergies, contraindications, interactions, current product information, and local institutional policy.
An arithmetic result is not a prescription. QuickMedCalc cannot confirm that the product, concentration, or patient information is correct. Do not start, stop, or change a medicine from a calculator result alone. A qualified healthcare professional should verify the information before administration.
Thresholds and result interpretation
A result above or below a cutoff does not automatically establish a diagnosis, and a risk category does not automatically prescribe a treatment. The same number can have a different meaning in another population, time window, or clinical setting. A page should show a threshold, category, or treatment meaning only when it is genuinely defined by the original model or a currently applicable authoritative source. Even then, interpretation depends on the stated population and context. Neutral wording on a result card is not patient-specific advice.
Current review limitations
QuickMedCalc is developed and maintained by an independent developer. Medical content is not independently reviewed by a physician. AI and software tools may assist research, coding, testing, and editing, but AI is not a physician or an independent medical reviewer. Source and implementation checks are not physician review, and automated testing is not clinical validation. The independent developer remains responsible for publishing, maintenance, and correction decisions. Learn more on the About page and Sources and Review Process.
Regulatory status
QuickMedCalc does not claim that this website or its calculator pages have received medical-device clearance, approval, registration, filing, certification, or conformity assessment. In particular, it does not claim FDA clearance or approval, EU medical-device CE marking or conformity assessment, or NMPA medical-device registration or filing.
Software classification depends on the specific functions, intended use, target users, and applicable law. Do not present this site as a regulator-authorized autonomous diagnostic, treatment, or clinical-decision system. Some environments may require a system with applicable regulatory authorization. This page does not provide regulatory or legal advice.
Report an error or outdated source
Reports may cover a formula, coefficient, threshold, unit, input definition, intended population, time window, result explanation, citation, guideline or policy version, historical-model label, or technical or accessibility problem. Where possible, include the page URL, a clear description, and a supporting original or official source. Do not send patient-identifying information. Potential medical-safety issues are prioritized for verification, but no fixed reply or correction time is promised.
