Nanograms per millilitre is abbreviated as ng/ml. Results of lab tests are frequently expressed in this unit of measurement. For instance, progesterone levels in human blood are measured in nanograms per millilitre in laboratory examinations.
The prostate gland produces a protein called prostate-specific antigen, which is quantified in nanograms per millilitre in the blood. The same holds true for determining the blood’s vitamin D content.
Sometimes ng/ml is used as the measuring unit in drug tests. For instance, the blood’s marijuana metabolites are measured in nanograms per millilitre during a marijuana drug test.
