Methodology & Clinical Sources
All calculation formulas, diagnostic thresholds, and patient educational guidance on BP Readings are strictly derived from peer-reviewed cardiology and endocrinology guidelines.
Core Editorial & Clinical Principles
Complete Integrity with Primary Guidelines
We never alter clinical cutoffs or invent proprietary stages. Our blood pressure classifications correspond strictly to international consensus guidelines, and our glucose thresholds mirror published standards.
Mathematical Rigour & Verifiable Formulas
Our HbA1c converter utilises the peer-reviewed regression model established by the ADAG clinical trial. MAP and pulse pressure calculations reflect standard cardiovascular haemodynamics.
Plain-English Communication for Seniors
Medical information must be understandable to be useful. We translate intricate physiological mechanisms into accessible language with high contrast, large typography, and zero confusing medical jargon.
Primary Clinical References & Published Guidelines
Every threshold on bpreadings.com is cross-referenced against these landmark publications:
2017 ACC/AHA Guideline for the Prevention, Detection, Evaluation, and Management of High Blood Pressure in Adults
Whelton PK, et al. Journal of the American College of Cardiology (JACC) 2018;71(19):e127-e248.
Application: Defines the 5 BP categories (Normal <120/<80, Elevated 120-129/<80, Stage 1 130-139 or 80-89, Stage 2 ≥140 or ≥90, Crisis >180 and/or >120).
Translating the A1C Assay Into Estimated Average Glucose Values (ADAG Study)
Nathan DM, et al. Diabetes Care 2008;31(8):1473-1478.
Application: Established the official linear regression formula: eAG (mmol/L) = 1.59 × HbA1c − 2.59 and eAG (mg/dL) = 28.7 × HbA1c − 46.7.
American Diabetes Association (ADA) Standards of Care in Diabetes
Diabetes Care 2024;47(Suppl. 1):S1-S343.
Application: Defines diagnostic cutoffs: Normal HbA1c < 5.7%, Prediabetes 5.7%–6.4%, Diabetes ≥ 6.5%; Fasting normal 3.9–5.5 mmol/L.
Measurement of Blood Pressure in Humans: A Scientific Statement From the American Heart Association
Muntner P, et al. Hypertension 2019;73(5):e35-e66.
Application: Standardised home blood pressure measurement protocol: 5 minutes rest, back supported, arm at heart level, multiple consecutive readings.
Review & Maintenance Cycle
Our clinical reference content is reviewed quarterly by healthcare professionals to ensure alignment with newly released society consensus statements and guideline updates.
