readyAveraging the readings…
What this is not. This summarises the numbers you enter. It is not medical advice, it cannot diagnose or interpret your readings, and it does not replace a clinician. Thresholds for home readings differ from clinic readings and vary by individual — use the values your own clinician gave you. Seek urgent medical care if you have symptoms such as chest pain, severe headache, breathlessness, or vision changes, rather than relying on any summary.
