How do I convert Kynurenic acid (CSF) from ng/mL to nmol/L?

nmol/L = ng/mL × 5.286. In the other direction: ng/mL = nmol/L × 0.1892.

Which units are used for Kynurenic acid (CSF)?

Common units are ng/mL, nmol/L.

Neurology & psychiatry

Kynurenic acid in cerebrospinal fluid (neuroprotective NMDA antagonist)

Also known as: Kynurensäure (Liquor)

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

ng/mL nmol/L

10 nmol/L = 1.89 ng/mL

nmol/L	nmol/L = ng/mL × 5.286	ng/mL = nmol/L × 0.1892

Kynurenic acid (CSF) is reported in ng/mL or nmol/L. The page converts between the units only.

nmol/L × 0.1892 = ng/mL (exact factor 0.1892).
CSF values are only meaningful together with a blood sample taken at the same time; no established reference range is listed here.
