Brief Summary:

Elevated aldosterone levels were also shown to contribute to the excess morbidity and mortality. Literature shows aldosterone and renin levels differ between ethnicity and gender. There is no established reference intervals for these two hormone levels in Asian community. We aim to establish reference intervals for plasma aldosterone and direct renin concentrations among Malaysians residing in Sarawak using the chemiluminescent immunoassay (CLIA).

This is a cross-sectional study which will be conducted among ambulatory patients, healthy blood donors and healthy volunteers. 300 participants who fulfil study criteria will be recruited after informed consent.

Socio-demographic data and anthropometric measurements will be recorded. Blood will be taken for plasma aldosterone, renin, serum potassium and creatinine. Urine will be collected for estimation of 24-hour sodium excretion. Aldosterone and renin reference intervals will be established partitioned for gender.
