Plasma fibronectin concentration in normal subjects

Abstract
The plasma concentration of fibronectin was determined in 374 normal [human] subjects, newborn to 85 yr of age, by quantitative electroimmunoassay. The plasma fibronectin concentration was higher in males than in females and the concentration increased with age. No day-to-day or diurnal variation was found. Different stabilizers of blood did not influence the results.
