The cost of screening to rule out secondary hypertension can vary and is generally around 1,000 to 1,500 RMB, depending on the hospital chosen and local policies. Ruling out secondary hypertension requires physical examination, laboratory tests (including routine blood, urine, kidney function), special tests (including renal artery ultrasound, radionuclide nephrogram, renal artery CT, and magnetic resonance imaging), etc., and the cost is about 1,000 to 1,500 RMB, and the specific cost should be referred to the local hospitals and policies. Secondary hypertension is the phenomenon of elevated blood pressure due to some identified disease or etiology. Clinical manifestations are mainly symptomatic manifestations of the associated primary disease, sometimes making hypertension the main symptom because other symptoms are not obvious. It is recommended that patients who want to know the exact cost of screening should go to the hospital for counseling and, if diagnosed, be treated promptly under the guidance of a doctor.
