Opportunistic screening — this is not a diagnosis.
It does not replace medical assessment. The cut-offs come from PAPPS-semFYC, ESC 2024, ADA 2026 and the WHO. Any positive result needs confirming. No patient data leaves the browser. See the clinical content policy.
Check the unit before you type. The engine works in mg/dL and in % (DCCT), which is what Spanish labs report; UK labs report mmol/L and mmol/mol. Every convertible field has a unit selector, so pick yours — a glucose of 7 is diabetes in one unit and a severe hypo in the other, and both are perfectly plausible numbers.

Frequently asked questions
Does pharmacy screening replace a blood test from the doctor?
No. Screening at the counter is opportunistic: it picks up warning signs so you can refer, spots risky drinking, or applies a validated questionnaire (PHQ-2, AUDIT-C, Fagerström). Any positive result needs confirming clinically.
My lab reports mmol/L. Can I still use this?
Yes. Every convertible field has a unit selector, and the value is converted before it is scored — glucose and cholesterol between mg/dL and mmol/L, and HbA1c between % (DCCT) and mmol/mol (IFCC). This matters more than it looks: a glucose of 7 is diabetes in mmol/L and a severe hypo in mg/dL, and both are plausible numbers, so getting it wrong produces a confident wrong answer rather than an error.
When is a high blood pressure reading urgent?
A reading of 180/120 or above WITH neurological or visual symptoms, chest pain or breathlessness is a hypertensive emergency: send them to emergency care now. Above 180/120 with no such symptoms still needs urgent care the same day.
What do I do if someone screens positive on the PHQ-2?
Move on to the full PHQ-9 to grade the depression. If there is any thought of death or self-harm, that is an urgent mental health referral — and give them the local crisis line (116 123 for Samaritans in the UK and Ireland, 988 in the US).
What is SCORE2, and does it apply outside Europe?
SCORE2 (ESC 2024) estimates the 10-year risk of a fatal or non-fatal cardiovascular event in people without established cardiovascular disease. The thresholds here are for a low-risk region — Spain, and also the UK and Ireland: low under 2.5%, moderate 2.5-7.4%, high 7.5-14.9%, very high 15% or more. SCORE2 is not validated outside Europe.
