ALBUMINURIA CATEGORIES IN CKD Category AER (mg/24 h) ACR (approximate equivalent) Termsa (mg/mmol) (mg/g) ACR, albumin-creatinine ratio; AER, albumin excretion rate; CKD, chronic kidney disease. a Formerly known as normoalbuminuria, microalbuminuria, and macroalbuminuria. b Relative to young adult level. c Including nephrotic syndrome (albumin excretion usually >2200 mg/24 h [ACR >2200 mg/g; >220 mg/mmol]). GLOSSARY OF TERMS FOR BLOOD PRESSURE MEASUREMENT Terms De nition Standardized of ce blood pressure This is the recommended method for measuring blood pressure in the current revised guideline. Blood pressure measurement following all guideline-recommended preparations as presented in Figure 2. The device used is not part of the de nition. Routine of ce blood pressure Blood pressure measured in the provider s of ce. Preparation before measurement and the device used are not part of the de nition. The values are often inconsistent between providers performing the measurements. In addition, it does not bear a reliable relationship with standardized of ce blood pressure. Manual blood pressure Blood pressure obtained using a manual auscultatory blood pressure cuff, instead of an automated method, with either a mercury or aneroid sphygmomanometer. Preparation before the measurement is not part of the de nition. Automated of ce blood pressure (AOBP) Blood pressure obtained in the provider s of ce using an automated device that is programmed to start only after a set resting period and measured several times with xed intervals between measurements. An average reading is then provided as the output. Preparation before measurement and attendance by the provider are not part of the de nition.
