Unit Conversion for Aldosterone
5.4 ng/dL of aldosterone equals 54 pg/mL or approximately 150 pmol/L.
Conversion Calculations
Converting ng/dL to pg/mL
- To convert from ng/dL to pg/mL, multiply by 10 1
- 5.4 ng/dL × 10 = 54 pg/mL
Converting ng/mL to pmol/L
- To convert from ng/mL to pmol/L (SI units), use the conversion factor of 7.1429 1
- First convert ng/dL to ng/mL: 5.4 ng/dL = 0.054 ng/mL
- Then: 0.054 ng/mL × 7.1429 = 0.386 nmol/L = 386 pmol/L
- Alternatively, 54 pg/mL ÷ 360.4 (molecular weight) × 1000 = 150 pmol/L (approximate)
Clinical Context for Aldosterone Levels
Reference Ranges and Interpretation
- For primary aldosteronism screening using the aldosterone-to-renin ratio (ARR), plasma aldosterone concentration should be at least 10-15 ng/dL (100-150 pg/mL) in addition to an elevated ratio for a positive test 2, 3
- A level of 5.4 ng/dL (54 pg/mL) is below the typical threshold used for confirming primary aldosteronism 2
Testing Conditions
- Blood should be collected in the morning with the patient seated for 5-15 minutes immediately before collection 2, 3
- Patients should be potassium-replete before testing, as hypokalemia can suppress aldosterone production 2, 3
- Interfering medications (ACE inhibitors, ARBs, beta-blockers, diuretics) should ideally be discontinued when clinically appropriate, with ACE inhibitors and ARBs stopped for at least 2 weeks prior to testing 4
