ngmL

ngmL is commonly used as an abbreviation for nanograms per milliliter, a unit of concentration. The conventional notation is ng/mL, with a slash, but the compact form ngmL sometimes appears in tables, data files, or shorthand references.

This unit expresses how many nanograms of a substance are present in each milliliter of a solution. It is widely used in clinical chemistry, pharmacology, toxicology, and biomedical research to report drug levels, hormones, metabolites, and biomarkers.

Common measurement techniques include LC-MS/MS and immunoassays. The numeric values are context-dependent and require appropriate calibration and reference ranges. Therapeutic drug monitoring often reports drug concentrations in ng/mL (for example, tacrolimus trough levels in the range of several ng/mL).

Conversion note: 1 ng/mL equals 1 microgram per liter (µg/L).

Disambiguation: While ng/mL is the standard concentration unit, ngmL as a string may be encountered in data fields, product names, or informal usage. There is no single entity universally identified by ngmL.
