Worked example

11.1 pmol/L (middle of the reference range) = 36.9 pg/mL

Conversion formulas

pg/mL	pg/mL = pmol/L × 3.326	pmol/L = pg/mL × 0.3007
ng/dL	ng/dL = pmol/L × 0.3326	pmol/L = ng/dL × 3.007

Good to know

Vasoactive intestinal peptide (VIP) in plasma is reported in pg/mL or in pmol/L.

pg/mL × 0.3007 = pmol/L; 75 pg/mL equals about 22 pmol/L.
The sample must be drawn into a cooled tube and frozen quickly, because VIP breaks down fast.

Reference range

Unit	Adults
pmol/L	0 – 22.2
pg/mL	0 – 73.83
ng/dL	0 – 7.384
