Normal dopamine figures can vary slightly across age groups. Dopamine levels can be measured with urine or plasma testing. With plasma testing, adults should have 10 to 20 nanograms of dopamine at any given time, depending on their activity level. Children ages 17 and younger should have less than 60 picograms.
