Figure 3

Relationship between the percentages of big big PRL (as determined by gel filtration chromatography) present in serum samples from 326 hyperprolactinemic patients (269 without macroprolactinemia and 57 with macroprolactinemia) and percentages of serum PRL precipitated by PEG. The horizontal line denotes the 50% limit for percentage of macroprolactinemia, and the vertical line is set to 49.2% of serum PRL precipitated by PEG (see Section 3).
