Basic and Optional Laboratory Tests for Primary Hypertension Basic testing Fasting blood glucose* Complete blood count Lipid profile Serum creatinine with eGFR* Serum sodium, potassium, calcium* Thyroid-stimulating hormone Urinalysis Electrocardiogram Optional testing Echocardiogram Uric acid Urinary albumin to creatinine ratio *May be included in a comprehensive metabolic panel. eGFR indicates estimated glomerular filtration rate. 8.1.2. BP Treatment Threshold and the Use of CVD Risk Estimation to Guide Drug Treatment of Hypertension Recommendations for BP Treatment Threshold and Use of Risk Estimation* to Guide Drug Treatment of Hypertension References that support recommendations are summarized in Online Data Supplement 23. COR LOE Recommendations I SBP: A 1. Use of BP-lowering medications is recommended for secondary prevention of recurrent CVD events in patients with clinical CVD and an average SBP of 130 mm Hg or higher or an average DBP of 80 mm Hg or higher, and for primary prevention in adults with an estimated 10-year atherosclerotic cardiovascular disease (ASCVD) risk of 10% or higher and an average SBP 130 mm Hg or higher or an average DBP 80 mm Hg or DBP: C-EO I C-LD 2. Use of BP-lowering medication is recommended for primary prevention of CVD in adults with no history of CVD and with an estimated 10-year ASCVD risk <10% and an SBP of 140 mm Hg or higher or a DBP of 90 mm Hg or higher.S8.1.2-3,S8.1.2-10 S8.1.2-13 *ACC/AHA Pooled Cohort Equations (http://tools.acc.org/ASCVD-Risk- to estimate 10-year risk of atherosclerotic CVD. ASCVD was defined as a first CHD death, non-fatal MI or fatal or non-fatal stroke.
