Neuron-specific enolase (serum) unit converter

Marker of neuronal/neuroendocrine cell damage; used after cardiac arrest and in SCLC

Also known as: NSE, Enolase 2, Gamma-enolase

Converter

Enter a value in any unit and all other units fill in.

ng/mL = µg/L pg/mL µg/dL ng/dL

Worked example

8.5 ng/mL (middle of the reference range) = 8 500 pg/mL

Conversion formulas

pg/mL	pg/mL = ng/mL × 1000	ng/mL = pg/mL × 0.001
µg/dL	µg/dL = ng/mL × 0.1	ng/mL = µg/dL × 10
ng/dL	ng/dL = ng/mL × 100	ng/mL = ng/dL × 0.01

Good to know

Neuron-specific enolase (serum) is reported in ng/mL or µg/L. The page converts between the units only.

1 µg/L = 1 ng/mL; the two notations are interchangeable.
The range shown is a guide from the named source; targets and reference ranges differ between laboratories, methods and indications, so compare with the range on your own report.

Reference range

Unit	Adults
ng/mL = µg/L	0 – 17
pg/mL	0 – 17 000
µg/dL	0 – 1.7
ng/dL	0 – 1700

Frequently asked questions

How do I convert Neuron-specific enolase (serum) from ng/mL to pg/mL?

pg/mL = ng/mL × 1000. In the other direction: ng/mL = pg/mL × 0.001.

What is the reference range of Neuron-specific enolase (serum)?

For adults the range is 0 – 17 ng/mL (Severn Pathology (North Bristol NHS Trust): Neuron specific enolase). Reference ranges differ between laboratories and partly by sex and age; use the range printed on your lab report.

Which units are used for Neuron-specific enolase (serum)?

Common units are ng/mL, pg/mL, µg/dL, ng/dL.
