Aldosterone pmol/L → ng/dL
Convert aldosterone from pmol/L to ng/dL
Converts units only; reference ranges depend on the laboratory, the assay and the patient.
What is the Aldosterone pmol/L → ng/dL?
This converter turns aldosterone from pmol/L, the SI unit used in UK reports and many European endocrine publications, into ng/dL, the unit of much of the US literature and of many published screening protocols. It divides by 27.75 (equivalent to multiplying by about 0.03604), derived from the molar mass of aldosterone, 360.4 g/mol.
When to use it
- Reading an aldosterone value from a UK or other SI-reporting letter in ng/dL
- Applying a study or protocol written in ng/dL to a result reported in pmol/L
- Recalculating an aldosterone/renin ratio after bringing both components into matching units
- Comparing serial results from laboratories that report in different units
When not to use it
- Results in nmol/L — multiply by 1000 first to get pmol/L
- Interpreting the result: reference intervals and screening thresholds depend on the assay, patient preparation, posture and guideline
How it is calculated
Aldosterone (ng/dL) = aldosterone (pmol/L) ÷ 27.75
Clinical pearls and limitations
- Converts units only; reference ranges depend on the laboratory, the assay and the patient.
- Dividing by 27.75 is the same as multiplying by 0.03604; dividing by about 28 gives a quick estimate.
- If a local report uses pg/mL or ng/L, multiply the ng/dL result by 10 to compare (1 ng/dL = 10 pg/mL = 10 ng/L).
- Renin activity (an enzymatic rate) and direct renin concentration are different measurements; a ratio cut-off defined with one cannot be applied to the other by unit conversion alone.
- A low renin makes the ratio very sensitive to the renin value near the assay's detection limit; many protocols therefore also require a minimum aldosterone concentration.
Frequently asked questions
How do I convert aldosterone from pmol/L to ng/dL?
Divide by 27.75. For example, 470 pmol/L ÷ 27.75 = 16.9 ng/dL and 190 pmol/L ÷ 27.75 = 6.8 ng/dL.
How do I get from pmol/L to pg/mL?
Convert to ng/dL and multiply by 10, or divide pmol/L by 2.775. For example, 470 pmol/L is 16.9 ng/dL, which is 169 pg/mL.
Does the aldosterone/renin ratio change when I convert aldosterone?
Yes — the numerical ratio changes with the units of both components. Converting only aldosterone and dividing by a renin value in other units produces a number that cannot be compared with any published threshold.
