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 the 2017 AHA/ACC guidelines, and our glucose thresholds mirror the annual American Diabetes Association (ADA) Standards of Care.
Mathematical Rigor & Verifiable Formulas
Our A1C converter utilizes the peer-reviewed regression model established by the A1C-Derived Average Glucose (ADAG) clinical trial. MAP and pulse pressure calculations reflect standard cardiovascular hemodynamics.
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/AAPA/ABC/ACPM/AGS/APhA/ASH/ASPC/NMA/PCNA 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, Kuenen J, Borg R, Zheng H, Schoenfeld D, Heine RJ. Diabetes Care 2008;31(8):1473-1478.
Application: Established the official linear regression formula: eAG (mg/dL) = 28.7 × A1C − 46.7 and eAG (mmol/L) = 1.59 × A1C − 2.59.
American Diabetes Association (ADA) Standards of Care in Diabetes
Diabetes Care 2024;47(Suppl. 1):S1-S343.
Application: Defines diagnostic cutoffs: Normal A1C < 5.7%, Prediabetes 5.7%–6.4%, Diabetes ≥ 6.5%; Fasting normal 70–99 mg/dL (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: Standardized 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 biomedical informatics professionals to ensure alignment with newly released society consensus statements and guideline updates.
