I have been diagnosed with primary hypertension. all my investigations are normal: Urine protein, Urine creatinine, urine noepinephrine and dopamine, Kidney Function Test, Liver Function Test and Thyroid Tests. My kidney scans are normal and eGFR is normal as well. electrolytes and fasting blood sugar are normal too.
But my renin is very high 291.10 ng/L (normal is 2.6-27.7). My aldosterone is normal so as with my aldosterone and renin ratio is normal. I was taking candesartan 32 mg a day for 1.5 years already but now shifted to 2 weeks exforge lowest dose. my worry is about my renin value why it is so high and what is the indication of it? what medication can be given to me in this case. thanks you very much for the answer.
