In an emergency
If you think you or someone else may be experiencing a medical emergency, including chest pain, difficulty breathing, signs of stroke, severe bleeding, or thoughts of harming yourself: contact your local emergency services immediately (999 in the UK, 911 in the US, 112 across the EU, 000 in Australia) or go to your nearest emergency department. Do not rely on this website.
Reference ranges are indicative only
Laboratory reference ranges vary between laboratories, testing methods, units and populations, and may differ by age, sex and pregnancy. The values shown on this site are typical adult ranges provided for orientation. The authoritative range for your result is the one printed on your own laboratory report.
Accuracy and currency
We make genuine efforts to keep content accurate and to base it on peer-reviewed sources, but medicine changes and errors are possible. We make no warranty that content is complete, current or error-free. If you spot something wrong, please tell us via our contact page.
External links
We link to external sources, including journal articles and health organisations, so you can verify what we say. We are not responsible for the content, accuracy or availability of external websites, and a link does not imply endorsement.

How we approach clinical accuracy
We are aware that health information on the internet is often inaccurate or outdated. To mitigate that risk, HealthReview content is written and medically reviewed by Suman Konda, a registered clinical pharmacist. Clinical statements are cross-referenced with peer-reviewed literature indexed on PubMed or from institutional reference works such as the NCBI Bookshelf and WHO technical documents. Where a source is used to support a specific claim, it is linked at the bottom of the page.
Despite these efforts, clinical knowledge evolves and errors are possible. Reference ranges, drug doses, and treatment guidelines can change as new evidence emerges. We review and update pages when new guidance is published or when a reader flags an inaccuracy. The "last reviewed" date on each article reflects the most recent editorial check.
If you believe any content is clinically incorrect, please contact us with the specific claim and your supporting source. Verified corrections are applied promptly.
Third-party sources and external links
This site links to third-party websites, including journal publishers, NHS resources, US National Institutes of Health databases, and Australian health authorities, so that readers can verify what we have written or read further. These links are not endorsements. We have no control over and are not responsible for the accuracy, availability, or content of external websites. A third-party website being linked here does not mean we endorse the entirety of its content or any products it sells.
International users
HealthReview is written with a global readership in mind and references clinical standards from multiple countries, including the UK, US, Australia, Canada, and India. Reference ranges, drug names, and clinical thresholds can vary between countries and between laboratories. The values presented are indicative. The authoritative guidance for any individual is the information on their own laboratory report and the advice of the clinician treating them in their local healthcare system.
Children and vulnerable users
This site is not designed for use by children under 13. Content is written for adult patients and their carers. If you are seeking health information about a child, please consult a paediatric healthcare provider. Nothing on this site constitutes advice for the diagnosis or treatment of conditions in children.
