DHEA-S µmol/L → µg/dL
Convert dhea-s from µmol/L to µg/dL
Converts units only; reference ranges depend on the laboratory, the assay and the patient.
What is the DHEA-S µmol/L → µg/dL?
This converter turns DHEA-S from µmol/L, the SI unit used in UK and other SI-reporting laboratories, into µg/dL, the unit on many reports in Germany, Austria, Turkey and the USA. It divides by 0.02714 (equivalent to multiplying by 36.85), the factor derived from the molar mass of DHEA sulfate, 368.5 g/mol.
When to use it
- Reading a DHEA-S value from an SI-reporting letter or study in µg/dL
- Comparing serial results when a patient changes laboratory
- Applying a µg/dL-based paediatric or gynaecological reference to a result reported in µmol/L
When not to use it
- Results in nmol/L — divide by 1000 first to get µmol/L
- Unconjugated DHEA or androstenedione, which have different molar masses
- Interpreting the converted value: reference intervals depend heavily on age, sex and assay
How it is calculated
DHEA-S (µg/dL) = DHEA-S (µmol/L) ÷ 0.02714
Clinical pearls and limitations
- Converts units only; reference ranges depend on the laboratory, the assay and the patient.
- Dividing by 0.02714 is the same as multiplying by 36.85; multiplying by about 37 gives a quick estimate.
- If the report gives µg/mL, the µg/dL value is 100 times larger — a frequent source of apparent hundred-fold discrepancies.
- Exogenous DHEA supplements raise DHEA-S; ask about over-the-counter products before interpreting a high value.
- Glucocorticoid therapy suppresses adrenal androgen production and lowers DHEA-S.
Frequently asked questions
How do I convert DHEA-S from µmol/L to µg/dL?
Divide by 0.02714 (or multiply by 36.85). For example, 6.2 µmol/L ÷ 0.02714 = 228 µg/dL.
What is 1 µmol/L DHEA-S in µg/dL?
1 µmol/L corresponds to 36.85 µg/dL, because 368.5 g/mol × 1 µmol/L = 368.5 µg/L = 36.85 µg/dL.
Why do DHEA-S results differ between laboratories even after conversion?
The unit conversion is exact, but immunoassays and LC-MS/MS methods are calibrated differently, and each laboratory sets its own age- and sex-specific ranges.
